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.

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. AI has made writing code 10x faster, but shipping is still painfully slow. 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.

Frontend: Typescript, React, Next.js, AWS Backend: Typescript, Node, AWS Data pipelines: Dagster, Python, polars CI/CD: GitHub Actions

Trayd | Engineers + Product / Ops Roles | NYC (ONSITE) https://buildtrayd.com

https://jobs.ashbyhq.com/trayd

Trayd is building the financial operating system for commercial construction. Contractors still run payroll, compliance, and job costing across spreadsheets and legacy software. We replace that stack with a single platform that automates payroll, union compliance, time tracking, and job costing.

Construction payroll alone moves ~$260B annually in the U.S., and most of the industry still runs on outdated tooling. We’re rebuilding that infrastructure from the ground up.

Small, senior team with high ownership. Engineers own systems end to end and work directly with leadership and customers.

Stack: TypeScript, React, Next.js, React Native, Node.js, Postgres

Location: NYC (SoHo office), fully in person.

For US roles, you can expect regular raises & bonuses, equity, and benefits including: health insurance, 401k matching (Vanguard), annual learning stipend, unlimited PTO, parental leave, and more. I take about 4-5 weeks vacation a year, in addition to ~3 weeks worth of company holidays (federal holidays + the week of Christmas to New Years.)

Folks in other countries can also expect a strong benefits package, but I'm not as versed on the details.

Additionally, you get a 5-week sabbatical after 5 years of employment - I took mine about a year ago, and it was fantastic.

To apply, please submit your info on the website, and our recruiting team will get in touch with you. If you have questions, feel free to reply here or contact me directly. (I'm an engineer on the iOS team, but I'll do my best to answer questions.)
