Hearo (Remote) — Founding Engineer — AI Product Intelligence Platform

Apply: https://yourhearo.netlify.app/

Hearo is building an AI platform that turns public internet conversations (Reddit, app reviews, online communities) into structured product intelligence. The goal is to help founders and product teams understand what users actually think about products by analyzing discussions at scale.

We’re looking for a founding engineer to help build the first version of the platform.

The core technical work involves ingesting large volumes of public conversation data, building reliable async data pipelines, and implementing retrieval-augmented generation (RAG) systems that transform noisy discussions into useful insights like product pain points, feature requests, sentiment trends, and competitor signals.

Tech stack is flexible but will likely involve Python or Node.js, Postgres, vector search (pgvector/Pinecone), and LLM APIs (OpenAI/Anthropic). Experience with backend systems, APIs, scraping, or data pipelines is especially valuable. Experience building LLM or RAG systems is a strong plus.

We’re looking for someone who enjoys early-stage product building and is comfortable owning systems end-to-end.

If this sounds interesting, apply here: https://yourhearo.netlify.app/

Spruce (London/Bristol, UK) — Lead Full Stack Engineer — £85–120k + equity — Hybrid

Spruce builds the operating system for heat pump installation businesses across the UK. The UK needs to install 600,000 heat pumps a year to hit net zero by 2050 — right now we're at ~100,000. We're building the software to close that gap, supporting 500+ installers and growing fast. Founded early 2024, VC-backed.

The problems are genuinely interesting: 2D floor-plan geometry and drawing tools, offline-first PWAs with sync conflict resolution, cross-company job sharing with RBAC permissions, underfloor heating physics and hydronics calculations, LiDAR integration, and solar and battery systems.

Stack: TypeScript, React, Node.js, PostgreSQL/PostGIS, Prisma, Docker, Konva, Tailwind.

You'd own slices of architecture and technical strategy, write high-leverage code on critical paths, and mentor a growing engineering team — while still spending most of your time hands-on.

Looking for someone strong in TypeScript across the full stack, who's product-minded and wants real ownership over what they build.

33 days holiday + 30 days/year working abroad. Hybrid (2 days/week in office). Nursery benefits.

Shorebird | Mid/Senior Software Engineer (Cloud) | REMOTE (North America) | Full-time | $150-220k + equity + benefits | https://shorebird.dev

Flutter is used by millions of devs (and nearly ⅓ of free apps submitted to AppStore), but is missing services for businesses. I built Flutter at Google. Now we’ve built a company selling services to 1000s of Flutter-using businesses globally, on track to profitability this year.

We serve 100s of millions of devices from our cloud, (2k+ RPS sustained), built mostly in Dart on Google Cloud + CloudFlare. We’re in the process of launching a series of CI offerings and have a lot of cloud development work ahead of us. You need production cloud experience, want to work at a startup, and be up for the challenge of owning, developing, and expanding Shorebird’s cloud infrastructure and backend services including code, configuration, architecture, and more. Previous Dart experience is not required.

Decise | Principal Engineer & Technical Strategist | Remote (US) | Fully Remote | Contract (1099)

Decise is a hands-on advisory and delivery firm that helps organizations unlock the full value of their technology and improve business profitability.

We work directly with executives to define what should be built, then we build it. Our work spans software engineering, data platforms, analytics, and customer-facing digital products. We often operate as fractional CIOs and CTOs, guiding both the strategic direction and the technical execution of our clients’ technology initiatives.

Our clients rely on us to turn complex business problems into working systems — not slide decks.

We are intentionally small and senior. Everyone on the team is a builder who can operate independently, solve complex problems, and deliver finished systems that people actually use.

White-glove service. Blue-collar grit.

We’re looking for a principal-level technologist who can move between engineering, architecture, and client strategy. Most of your time will be spent building systems and writing production code. The rest will involve working directly with executives to shape technical direction and ensure the work creates real business value.

Typical technologies we work with include React, Angular, Next.js, Node.js, Go, Snowflake, SQL, dbt, Domo, Streamlit, AWS, Vercel, and modern AI-assisted engineering tools. The exact stack varies by client; the ability to learn quickly and move confidently across technologies matters more than any specific tool.

Strong candidates typically have 10–15 years of experience building production systems and are comfortable operating both as hands-on engineers and as technical advisors to executives.

This is a long-term, full-time independent contractor engagement (1099). Everyone at Decise — including the founders — operates in this structure. Compensation is designed to be competitive with senior engineering roles at leading technology companies.

The fastest way to stand out is to show us something you’ve built: a production system, GitHub repository, application, or data platform you designed.

Trunk | https://trunk.io Tech Lead (CI & Test Data Platform) - San Francisco HQ and open to Relo Marketing Lead (Developers) - Remote friendly Developer Advocate - San Francisco HQ and open to Relo Sr Platform Engineer - San Francisco HQ and open to Relo

Trunk is an a16z funded (25M) Series A dev tools startup, redefining software development at scale. At Trunk, our mission is to help teams create high-quality software quickly.

The bottleneck has shifted downstream - to merge conflicts, flaky tests, inconsistent code quality, and dozens of other frictions that drain productivity and morale. Engineering teams that can stay focused on designing, implementing, and delivering software will build magical, high-quality projects - and they'll be happier doing it. We're building a CI Reliability Platform that empowers teams to land code faster and develop happier!

Our products:

  * Merge Queue: Ensure your PRs keep the builds you care about green at any scale.

  *Flaky Tests: Detect and eliminate Flaky Tests.

We're looking for senior backend engineers. You'd work across our SvelteKit app (Postgres, Redis, Docker, ClickHouse), Python ML inference on GPU clusters, and k8s clusters across multiple cloud and GPU providers.

Some recent projects:

- building canary deploys with cookie-sticky traffic splitting - implementing durable execution for long-running workflows - designing our public API with OpenAPI docs auto-generated from Zod schemas - implementing enterprise-grade authentication, authorization, and permissions - optimizing ML inference for our hosted image generation models

We care way more about first-principles and core engineering skills rather than specific shenanigans around programming languages or particular tooling—knowing a lot about old UNIX principles is a plus though.

You should be comfortable owning things end-to-end. Experience with GPU infra is a plus. Many of us have some kind of creative background, it helps when building tools for creatives but is not a requirement by any means.
