DAT | Engineering Manager, Senior Engineering Manager | Seattle, Portland, Denver | Hybrid 2-3 days/week | Full-time | $192k - $261k

I'm hiring for both EM and Senior EM levels building the automation layer for freight pricing, matching, onboarding, and settlement. Lead 1-3 teams (FTE + contractors), own delivery end-to-end, ~8 yrs exp typical. I expect all managers to be technical and be able to help unblock the team, though your day-to-day wont be in the code.

Interesting problems: trust/fraud at marketplace scale; legacy-data-meets-modern-stack; and all kinds of problems that come with powering hundreds of billions of dollars worth of transactions every year.

AI/LLM: We are leaned in, but still hold humans responsible for what they push and expect everyone to review and understand llm output before asking other humans to look at a thing.

Culture: I am deeply familiar with Google's project oxygen/aristotle and am building a culture where our teams can do great work with minimal bs.

Location: Must be local to one of our three locations (Seattle, Portland, Denver)

Primary Tech: Node/TS, React, GraphQL, Kafka/redpanda, k8s, AWS, etc

Prophet Town LLC | Various Software Engineering Roles | US – Remote and Hybrid | English fluency required | Full-time | $150K-$260K annual total comp (multiple)

We are a people-first, boutique tech agency creating on-demand teams and software solutions for long-standing clients. These clients trust us to practice engineering excellence as though we were members of their own staff. Our leadership team is ex-Fortune 100 with software engineering backgrounds: we’re still coding. Notable recent projects include a gigantic ERP migration for Anduril, and working with Surge Labs to help develop some of the frontier LLM models themselves (yes, seriously). This is a remote-first agency, but some projects involve onsite work.

I’m the founder and CEO, and I’m trying to do what I call “enlightened business”. I take responsibility for both staff and clients, and I look for people who approach their work with a similar sense of ownership. Applicants must meet a high bar - I personally review every hire. In return you’ll get:

  * Flexibility and a low-bureaucracy environment
  * Clients that won’t treat the vendor like “the B Team”
  * The chance to act as a code architect, not just implement tickets
  * Exposure to a wide variety of industries and modern challenges
  * Me as your personal champion and advocate

We’re currently especially seeking:

  * Back-end, Front-end, and Full-Stack Software Engineers, Tiers 3 and 4

Tier 3 roles are typically 5-10 years experience with $150-$180K total comp.

Tier 4 roles are 11-20 years experience, $215-$260K total comp. Higher tiers exist, and we always welcome exceptional applications.

Though not yet universal, many of our clients are now demanding senior/staff engineers with success using modern agentic approaches. Be ready to explain where current models work well and where they do not.

Please apply using this Google Form: https://forms.gle/R5b8FaGEM7CSJzsC7

Also because posting some visibility has been popular with you guys: * We got 170 responses to our July HN Who's Hiring, and made 3 offers. * We're hoping to hire about 5 people before August 31, even though we're starting a little late.

We're hiring a Principal Engineer, backend-heavy role (85-90% backend), to own architecture across multiple teams and help set technical direction as we scale.

Stack: TypeScript, Node.js, GraphQL, PostgreSQL, AWS, React/Next on the frontend.

You'd be:

Owning delivery on systems spanning multiple teams Driving adoption of AI coding tools (we use Claude Code) with real usage across the team, not just experimentation Mentoring senior engineers, influencing technical decisions without needing to go the management track Working closely with product and business leadership on technical strategy

Looking for 15+ years of experience, real hands-on TypeScript backend depth (Node.js, NestJS, or similar), and ideally some exposure to healthcare, fintech, or another regulated-data environment, though that's a plus, not a hard requirement.

Hybrid, 4 days/week in our SoHo office.

Tessellate | Full Stack Engineer | Hybrid | Nashville, TN | Full-time

Tessellate is pre-seed and early — this is a real chance to help build a startup from the ground floor, led by second-time founders. There are genuinely hard, interesting data challenges under the hood that push us to lean into AI and machine learning as part of the product itself. We expect our engineers to be AI-native: using the most advanced AI and cloud tooling to ship quality software at pace. Startups aren't for everyone — but you'll learn a great deal, own outcomes that matter, and share in the upside if we win.

We're hiring an associate to mid-level product engineer to build alongside our small team and ship features across the product — from a mobile-first frontend through the Python API and the data beneath it. This is a build-and-ship role: your week is spent turning product ideas into working, tested, shipped features that physicians use.

You won't be alone at the edges. We have fractional senior support for our infrastructure and a dedicated data engineer for the claims layer, so you can lean on real depth where you need it and stay focused on moving the product forward. What we need from you is momentum on the product itself.

Earl | AI product engineer | London | On-site 4 days/week | Fixed term to Dec 2026

We’re hiring an AI-native engineer to work with Earl on a live project inside a Premier League football club. This is not an AI strategy role, and it’s not a chatbot demo job. You’ll work directly with people inside the club's commercial team, find valuable problems, and build production AI systems that are actually used.

We’re looking for someone who can move from vague problem → technical design → working product quickly.

You do not need football experience.

You do need strong product judgement, the ability to work directly with non-technical users, and evidence that you’ve actually shipped things.

We’re particularly interested in people who build with AI as their default way of working, rather than conventional engineers who have recently added an LLM API to their CV.

To apply, send me:

- A short intro - 2-3 things you’ve built What you personally did - How you currently use AI to build software - Location and availability

Strong candidates will do a paid practical working session.

Odin | Senior Design Engineer, Senior Platform Engineer — Edge Systems | Remote (US) | Full-time

Odin is the workforce visibility and compliance platform for critical infrastructure. We protect the world’s largest construction projects, data centers, and critical assets—from groundbreaking through post-turnover—by unifying physical access control, workforce compliance, video monitoring, and drone surveillance in one command center. We’re already on 500+ active projects with 100K+ workers, securing over $100B in construction value.

We’re hiring two hands-on senior builders:

1. Senior Design Engineer: Research, design, and build the interfaces people use to run jobsites. You’ll establish Odin’s design language and production design system, create coded prototypes with mocked states, and implement responsive, accessible screens across desktop, tablet, and mobile. We’re looking for someone whose portfolio demonstrates customer research, strong product and interaction judgment, and substantial production frontend engineering.

2. Senior Platform Engineer — Edge Systems: Build the software connecting jobsites to Odin’s cloud. You’ll work with cameras, access-control readers, rugged devices, local compute, and constrained networks. You'll own device integrations, video and event ingestion, buffering, synchronization, remote deployment, diagnosis, and recovery. We’re looking for production experience with edge or distributed systems, intermittent connectivity, third-party hardware or protocols, and software operating beyond a conventional cloud environment.

Our stack includes TypeScript end to end, Node.js and GraphQL, React and CSS, React Native and Expo, Postgres, Kubernetes on GCP, and Datadog. Design Engineering uses Figma and Claude Design. Edge Systems integrates with technologies including CCURE 9000, Avigilon, HID, Zebra, Esper, and Iru.

Both roles require strong ownership, operational maturity, mentoring, and using AI to accelerate work without outsourcing judgment. These are individual-contributor roles and include periodic jobsite travel.

Sitewire | Full-Stack Software Engineer | Full-Time | $130-200k USD | 0-0.1% Equity | Remote (US only)

I'm the head of engineering at Sitewire, a construction finance platform that helps lenders and real estate investors track projects, automate work verification, and speed up payments. Our small, fully-remote team has built a profitable product that's expanded organically 3x per year, mainly through word of mouth. We're now looking to roughly double the size of our engineering team as we enter our next phase of growth.

We're looking for smart, pragmatic full-stack engineers who operate with a high degree of autonomy and ownership. This is not a ticket factory: you'll be working directly with our PM to turn product briefs into new platform features and will have a hand in shaping the architecture and design of the things you build.

Our current stack is React and React Native on the client side with Postgres as our database. Our web app and API are currently powered by a Ruby on Rails monolith that we're gradually migrating off of. You don't need experience with Rails and it's not what we're hiring for: we're looking for React experience + solid backend engineering experience with any modern language.

Our interview process is pretty simple: a phone screen/behavioral interview, a 1-hour coding challenge that you can complete as either a live session or a take-home (your choice), and a presentation on a project you designed and feel particularly proud of (or think is particularly interesting).

If you're interested, please fill out this form and I'll be in touch: https://forms.gle/diVa5ScKJLYnW7u38

Joulent | Founding ML Platform Engineer, Energy Intelligence | San Francisco | HYBRID | Full-time | equity

We deliver multi-gigawatt power to AI data centers, and this is the founding hire on the team that forecasts load and market prices. You own the whole spine: ISO/RTO market feeds, weather and plant telemetry through feature store, serving, drift detection and the model gateway.

Not a scale problem — the data is rich, not petabyte. Feeds land late and get revised after the fact without ever throwing an error, so the failure mode is a price series quietly wrong for three weeks behind a forecast that looks fine. The work is trust infrastructure: lineage, freshness SLAs, point-in-time correctness, eval gates that can block a model.

Python, SQL, Airflow, containers, IaC. 5+ years on production data and ML platforms; energy background welcome, not required.

Looking for: expert-level kdb+/q, engine internals, query planning/optimization, C API extensions, performance analysis. Nice to have: exposure to hardware acceleration concepts.

Apply: email amir@silicon45.com with your resume and a short note on 1-2 performance-critical kdb+ systems you personally built or optimized.
