Count | Senior Software Engineer | REMOTE (UK/Europe/US East Coast) | Full-time | £100–140k (or local equivalent) + Equity | https://count.co

Count is an infinite, real-time canvas where SQL, Python, and low-code query cells live side-by-side with visualizations and freeform whiteboarding. It replaces the traditional linear notebook with a collaborative space for modeling, analysis, and presentation.

Under the hood, we've built a custom WebGL rendering engine, data visualization library, graph-based modeling layer, and horizontally scalable compute engine (DuckDB-based) that dynamically shifts execution between browser and server to minimize latency and reduce database load.

You'll help evolve the core platform: integrating agentic workflows into data exploration, pushing the performance limits of our distributed execution layer, and building powerful new analytics experiences used daily by customers. You'll have high autonomy and ownership over major parts of the product and technical roadmap, from architecture through production.

Tech stack: TypeScript, Python, Node.js, WebAssembly, WebGL, Apache Arrow/Parquet, DuckDB, Kubernetes, React.

Spacelift | Remote (Europe) | Full-time | Senior Software Engineer | $80k-$110k+ (can go higher)

We're a VC-funded startup (recently raised $51M Series C) building an infrastructure orchestrator and collaborative management platform for Infrastructure-as-Code – from OpenTofu, Terraform, Terragrunt, CloudFormation, Pulumi, Kubernetes, to Ansible.

On the backend we're using 100% Go with AWS primitives. We're looking for backend developers who like doing DevOps'y stuff sometimes (because in a way it's the spirit of our company), or have experience with the cloud native ecosystem. Ideally you'd have experience working with an IaC tool, i.e. Terraform, Pulumi, Ansible, CloudFormation, Kubernetes, or SaltStack.

Overall we have a deeply technical product, trying to build something customers love to use, and have a lot of happy and satisfied customers. We promise interesting work, the ability to open source parts of the project which don't give us a business advantage, as well as healthy working hours.

If that sounds like fun to you, please apply at https://careers.spacelift.io/jobs/3006934-software-engineer-...

You can find out more about the product we're building at https://spacelift.io and also see our engineering blog for a few technical blog posts of ours: https://spacelift.io/blog/engineering

Waypoint AI | Senior Backend, Fullstack, Frontend | Prague + REMOTE (CZ) | Full-time | Equity

We're building Chip — an AI support engineer that autonomously triages, routes, and resolves complex technical support cases. Think: a teammate that reads every Jira ticket, every Intercom thread, and every runbook, then actually acts on them.

Czech-American B2B startup, raised $3.1M. Already in production with Volvo, ClickHouse, and others.

We're a small eng team where early architectural decisions still matter. We use AI daily as a collaborator (Claude Code) — not as a gimmick, but because it genuinely makes us faster. We value craft, ownership, and shipping in small slices.

Stack: Django + Django Ninja, Postgres, Dramatiq (background jobs), React/Next.js/TypeScript/Tailwind.

Hiring for three roles:

Senior Backend Engineer (AI Systems) — Own APIs, data pipelines, and durable workflows. LLM product experience (evals, cost/latency, vector search) is a plus. https://mywaypoint.ai/open-positions/senior-backend-engineer...

Fullstack Engineer — Backend-heavy with enough frontend to be dangerous. End-to-end ownership from schema to UI. https://mywaypoint.ai/open-positions/fullstack-engineer

Frontend Developer — Build interfaces that make complex AI feel simple. React/Next.js/TS/Tailwind. Product-minded, not just pixel-pushing. https://mywaypoint.ai/open-positions/frontend-developer

Office in Prague 7 (Holešovice), remote-friendly. Competitive CZ-market comp + meaningful equity.

To apply: joinus@mywaypoint.ai — include a project you shipped end-to-end and how you use AI tooling in your workflow. Mention HN.

Starbridge | Senior Engineers (Kotlin/Java/React/Typescript) | NYC or Remote | Full-time | starbridge.ai Starbridge is building an AI platform that turns large-scale public and enterprise data into reliable sales insights. We are early, moving fast, and building from zero to one, so this role will have huge ownership and product impact.

Product Engineer: (React/Typescript) who would work closely with product and design to build user-facing parts of the platform. You will craft performant, stable frontends that explain technical concepts to non-technical users and help us iterate fast based on customer feedback.

AI Engineer: Applied AI plus strong software engineering. You will build, evaluate, and deploy LLM-driven features like deep document analysis and interactive chat, working with models from OpenAI, Anthropic, and Gemini. Expect hands-on Python, ML system design, experimentation, and production reliability. Bonus for RAG depth and frameworks like LangChain, LlamaIndex, or Hugging Face.

Backend Engineer: (looking for Kotlin/Java/Scala experience). You'll work across the backend: building enterprise integrations, large-scale scraping and parsing pipelines, and systems that let users apply LLMs to millions of documents to generate insights at scale.

We're looking to build our in-person team in NYC but also open to remote!

Apply: https://starbridge.ai/careers and mention HackerNews or email recruiting@starbridge.ai with your resume.

Mondrio | Software Engineer (Founding Team) | REMOTE (Brazil) | 3-Month Trial-to-Hire

B2B SaaS pricing is still guesswork. We’re building the AI-powered monetization operating system to fix it. We are pre-seed, lean (4 people), and shipping to live customers.

The Experience: This is a unique "fast-track" for an ambitious junior/mid-level engineer. You’ll skip the corporate ladder and learn to build an AI-native company from the ground floor. You will own features end-to-end—no managers, no layers.

AI-Native Workflow: We are all-in on Claude Code for scoping and shipping. You get a seat on Day 1. If you aren't already 10x-ing your output with AI tools, we’ll teach you. It’s the most essential skill for the next decade of engineering.

The Work:

Integrations: Build OAuth 2.0 flows and data sync pipelines for pilot customers.

Northstar Module: Build a strategic intelligence module from scratch (DB, Backend, Frontend integration. We have most of designs already).

AI Personas: Use LLMs to turn raw customer data into actionable pricing strategy.

Stack: Python 3.12 (Typed), FastAPI, MongoDB/Beanie, React/TS, Gemini/Claude, Claude Code, Google Cloud, Docker, Pulumi

Who You Are: You write clean, typed Python and can navigate a React component. You use AI tools (Cursor/Copilot) to move fast but remain the pilot. You care about the "Why" behind the product.

Process: Intro call → Technical session → Founder chat. Decision in ~7 days.

Apply: Send a link to something you’ve built to manon@mondrio.com

Vidably | Founding Engineers and Designer | San Francisco (SF) | Full-time | Onsite

(I only have one JD posted publicly, but I'm hiring broadly for eng + design): https://www.linkedin.com/jobs/view/4330646312

I'm founder of Vidably and just closed a $1.5M pre-seed last week.

AI agents are about to orchestrate trillions in commerce, but today they shop on thin data: product specs, studio photos, and text reviews. Agents need evidence, not marketing. Today, the most influential product evidence lives on TikTok and Reels, outside the surfaces brands control and agents can use. Vidably puts verified buyer video directly onto e-commerce product pages through a lightweight widget. We capture that video post-purchase and link it to real purchasing outcomes. Every video is SKU-linked and structured so shopping agents can reason over it.

We're already seeing organic pull from creators and expansion from brands.
