Deep Core Technology | Founding Engineer | REMOTE (MUST LIVE IN CANADA) | Full Time | Salary: $105,000 - $125,000 CAD + equity

Company: We’re building a geologic modelling software, based on reasoning, to help mining and mineral exploration companies work faster. Our goal is to create a way to enable open-ended, interpretive geologic problem solving to be done programmatically, changing the way to explore for hard rock and critical minerals. Currently in active fundraising.

Role: You are the founding engineer on the team, joining co-founder (Neil, CEO) and myself (Jeff, CTO) as first employee. You’ll have a deep influence over systems and architecture. You will have ownership through the entire stack from the database, through geostatistical backend services, through 3D rendering on the client side.

Work rooted in agentic systems, so an understanding of the internals of things like Claude Code, and a broader understanding of orchestrating agents to complete complex discrete tasks is important.

You:

- Fluent in Typescript, Python, and framework/tooling agnostic (Currently using things like NextJS, Supabase, Cesium)

- Eager to learn about mining domain knowledge around the software.

- Ownership of the codebase, and the systems that support the software (project management, CI/CD, monitoring, etc.)

- Strong engineering fundamentals around architecture, systems and security.

- Open to doing a yearly month abroad with Neil and I. Last year, it was Oaxaca, Mexico.

Apply: Shoot me an email at jeff@deepcoretech.com with a resume, and a short blurb about yourself. If you include a 1 minute video/Loom, I'd love to see it. Must be eligible to work in Canada without a VISA requirement. We are located in Squamish, BC.

Wand | Senior Windows C++ Engineer | REMOTE (US Eastern timezone overlap required) | Full-time

Wand (40M+ gamers) builds the augmentation and intelligence layer for PC gaming — real-time game-state reading powering a unified ecosystem across desktop, web, and native in-game overlays. Contextual help, interactive maps, and video clipping delivered exactly when a player needs it, without alt-tabbing out of the game.

We're hiring a senior IC to own meaningful parts of the native infrastructure underneath all of that. This is platform-team work at the seam between Windows, third-party game engines, and our product. You'll make architecture calls the rest of engineering lives with for years, and you'll measure success by what other teams shipped on top of your foundation — not by what you personally wrote. Recently shipped: a plugin system for safe in-process extensions; current work includes a Lua scripting layer on top of it.

What we're looking for: - 7+ years C++, meaningful time on tools/engines/platform systems where your users were other engineers - Deep Windows native: Win32/64, DLL lifecycles, hooking, IPC, process/thread management, WinDbg/Process Monitor - Strong concurrent programming — you spot races and ordering bugs in review without a checklist - Plugin/extensibility experience: you've designed an interface someone else built on, and lived with the result - Outcome-oriented, low-ego

Bonus: Unreal/Unity internals, full-stack TS/Electron down to C++, scripting/SDK layer (Lua/AngelScript/DSL), OBS or video capture internals, gRPC/Protobuf/FlatBuffers.

Fully remote, competitive comp + equity.

Full-Stack Engineer with 3+ years of experience building production-ready React/TypeScript systems for SaaS, fintech, AI workflow, and data-heavy products.

I’m strongest in frontend-focused full-stack work: polished React/Next.js product interfaces, dashboards, auth flows, protected routes, API integrations, database-backed features, Stripe billing, deployment, QA, and debugging the production issues behind the UI.

Recent projects include MindPad AI, Flowstate, AtlasBrief, GeoRisk, and EchoRoom. These are not basic portfolio clones — they include real auth, payments, persistence, AI-assisted workflows, dashboards, billing logic, team flows, and deployed production-style architecture.

I’m looking for remote Frontend Engineer, Full-Stack Engineer, React Engineer, or Software Engineer roles where I can own real product work end-to-end and contribute quickly.

AES (associatedenvironmentalsystems.com) | Summer Software Engineering Intern | REMOTE (US, with occasional Boston-area days) | $30-40/hr | Full or part-time | June 15 – Aug 22, 2026

"The senior lead doesn't write code from scratch. Neither will you."

We're a tiny team building a field-service-management platform for AES, an environmental-test-chamber manufacturer. One senior lead, one part-time backend specialist, and we're hiring a summer intern. The product is pre-production with active user feedback driving the build — you'll ship features that real service coordinators and field technicians will use day-to-day.

The bar is NOT raw coding ability. We use Claude Code for all code generation. The bar is the ability to direct an AI at production engineering and catch it when it's wrong: schema literacy, diff-reading, end-to-end ownership.

Stack: Next.js 14 (App Router, RSC, Server Actions), TypeScript strict, Prisma + Postgres, Tailwind + shadcn/ui, NextAuth, Twilio, Anthropic SDK, Playwright. ~100K lines of TS with `any` banned by lint.

Must-haves: a track record building with AI tools (link your best AI-built work — a PR, a deployed project, or a repo, ideally with a CLAUDE.md), at least one shipped end-to-end project that runs somewhere a stranger can use, schema/data-flow literacy, clear written communication, strong academic record. TypeScript fluency NOT required from scratch.

Eligibility: US person, able to pass standard background check. We can't sponsor visas or hire F-1/OPT for this role.

Logistics: 20–40 hrs/wk flex, Mon–Fri, remote with occasional in-person days at AES Chelmsford MA or our coworking space in Waltham MA. W-2, paid hourly. Apps close June 8.

No leetcode. No whiteboard. Show us your best AI-built work — a PR, a deployed app, or a repo. Apply: https://tally.so/r/44pNxX

Uber | https://www.uber.com/ai-solutions | Senior Product Engineer | Full Time | Amsterdam, The Netherlands | Hybrid

We’re building a complex data labeling platform for AV and robotics teams working with multi-sensor data: images, point clouds, sequential data, and 3D scenes.

We’re hiring a Senior Product Engineer to help us ship the core web product faster and improve the quality of customer-facing labeling workflows.

Tech stack: Vue/React, TypeScript, Three.js/WebGL/WebGPU, TinyBase, Django.

You can help us solve problems like: - Making 2D and 3D annotation workflows faster, more precise, and easier to use - Designing point cloud tiling, autosave, undo/redo, review, filtering, and issue-tracking workflows that hold up under real labeling operations - Improving performance where milliseconds matter: rendering, local state updates, preloading, and geometric operations - Shaping API contracts, data models, permissions, background jobs, and operational tooling as the platform scales

This is a senior role with high ownership on a small team. To apply, please reach out to bert@segments.ai (we recently got acquired by Uber) with a resume and mention HN in your application.

neocom | Senior Frontend Engineer | Onsite | Munich, Germany | Full-time

We at neocom are building shop agents for online retailers. Customers can chat naturally, get clear guidance, and find the right product faster, just like talking to a great, opinionated salesperson in a physical store or like chatting with an LLM, that actually knows about the products in the shop and has an opinion about them.

Stpkr Technologies | Noida, India (Delhi NCR) | ONSITE | Multiple roles

Stpkr Technologies is hiring for the following roles to build the next generation of wearable devices.

We are currently looking for the following 4 roles but we are also open to interviewing any candidates who feel like they will do their best work here - even if your skillset/experience doesn't fit the current defined roles. Our current team doesn't fit the conventional mold, and we don't expect our future hires will either. If you don't fit the advertised roles, just send us a mail per the same process with whatever job title would fit you the best.

Work is in person near Noida Sector 18, walking distance from Sector 18 Metro Station. We prefer in office work, but we are super flexible overall, it will be hands down one of the best work environments you can get. Pay is competitive, and there are opportunities to earn meaningful equity down the line. We prefer current and recent undergraduates for our roles. If you are still in college we welcome you to apply nonetheless provided you can work as an intern for us in person. Super-flexible overall and all of our current team started out as interns.

Hiring across OS, full-stack, and hardware. AI policy across all roles: you should be able to do the work without AI, and much faster with it.

Android Systems Engineer (AOSP/BSP) - Everything at the OS layer. You've rooted phones, flashed custom ROMs, broken and fixed Linux for fun. Comfortable in C/C++. GitHub with kernel-adjacent or LineageOS-type projects a plus. Stack: Android, Linux, C, C++, Java. _Filter: send us something you built where you had to fight the OS or hardware.

Full-Stack Engineer (Apps + Backend + ML) - Everything at the platform layer. Generalist who ships end-to-end. Skill check: can build a crude-but-working facial recognition system (camera → model → DB → backend). (using existing facial recog models) Bonus for weird/constrained hardware work or running ML on edge devices. Stack: Android, Java, Python, TypeScript. _Filter: send the most useful thing you've built and used (no CRUD slop). Even better if you still use it for yourself.

Hardware Engineer - Bring-up/Debug/Integration - Take EVT/DVT boards and make them work. Comfortable with J-Link and IDE debugging, reading schematics and reference designs. KiCad/Altium/EasyEDA hobby work would make you ideal. PetaLinux experience or hunger to learn it. ECE undergrad fine. _Filter: photo of a board you designed or debugged, plus what went wrong.

Hardware Engineer - Power/RF/Wireless - Make the power and RF paths behave on EVT/DVT boards. Hands-on with schematic capture, layout, soldering, scope/logic analyzer. Given two unknowns, you pick one and start measuring. _Filter: sensor fusion work, how noise behaves across protocols, and SPI debug chops.

Founder's Office - Work closely with the founder and the rest of the team to manage the day to day and long term affairs of the company, the Man Friday of the company. Must have a decent degree of technical knowledge (we are a tech company after all) and be efficient at administrative tasks as well as management. Speed and learning ability are prized here, there will not always be a clear path to the work you have to do here, so you will have to figure some of it out on your own.

To apply, contact arnav@stpkr.in with the subject line "HN - Human" and a brief intro for further communication. Attach any documents you deem useful there. Please include the role you are applying for at the top of the email if it is one of the above mentioned, otherwise whatever role fits you best. Shortlisting will be online, interviews will be in person. We are hiring quickly, expect to hear back from us within 2-3 days of applying. If you don't, assume you will not. Thanks for your time!

Opaxa | Founding Full-Stack Engineer | San Francisco | Full-time | $200K–$300K + founding equity | opaxa.ai

Opaxa is the AI agent platform that runs restaurant back-office operations. Not another dashboard — agents that take the work off the operator's plate and act: build the schedule and push it to action, place the order with distributors, audit the invoice for overcharges, draft the review reply. The operator approves what matters; the rest gets done.

The unfair part: the founder owns and runs a 40-location restaurant company with over 750 employee's — so Opaxa's first customer is a real, operating restaurant group with real data and real stakes from day one. Deep domain expertise is built in, and your work runs in real restaurants immediately, not after a six-month hunt for a design partner. Well-funded.

A working prototype is already built. Now I'm hiring a founding full-stack engineer to take it from prototype to production: own the architecture, the agent runtime, the backend, and the integrations the agents act through (Toast, Paycom, Sysco, and more), set the technical bar, and grow the team behind you.

You'd work directly with me — I own product, customers, and the domain; you own the AI and the build. We'd be hiring additional engineers and account managers within the first year.

You're a fit if you: - have shipped agentic systems to production — plan-and-act, not chatbots or wrappers - are a strong full-stack builder (Python and/or Node, Postgres, real infra) - use the latest AI tooling (Claude Code / Cursor) as your default want to own a whole product as the first engineer, and eventually lead

Stack: React/TypeScript, Python/Node, Postgres, the Anthropic API, integrations across the restaurant stack.

To apply: email me at colton@opaxa.ai with the most impressive agentic system you've personally shipped — what it did, what you owned, and what made it hard — plus your resume or links. I read every one and reply. Please write it yourself; if it's clearly AI-generated, I'll pass.
