Senior Full Stack Engineer | Join the team behind a $3.2B smart-home exit, now taking on food waste | SF Bay Area (Hybrid) | $185K–$210K base

We've partnered with a Bay Area hardware company on one of the most exciting missions in climate tech: eliminating waste, starting with food. The pedigree is serious: the founders previously created one of the defining products of the smart-home era, a company acquired by Google for around $3.2 billion, and they have brought the same design obsession to food waste. The market has responded. Their home product is already in tens of thousands of kitchens, and with a commercial launch landing in 2027, next year is set for real growth. They are backed at Series C by a heavyweight group of climate and tech investors, including Breakthrough Energy Ventures and Amazon's Climate Pledge Fund.

This is a senior individual-contributor seat with real technical leadership attached, reporting to the Director of Software Engineering. You'll set the direction for your project area, write the code that anchors it, and lift the engineers around you. There's no frontend or backend divide here: everyone builds full stack and leans to their strengths, and teams form around projects, not layers. You'll go deep on one project, then rotate onto new parts of the codebase over time. What sets the team apart is how they build. AI-assisted development is central, not a novelty, and as a senior hire you'll be expected to use tools like Claude Code fluently and raise the bar for how everyone else does. And because it's a hardware company, your code runs on real devices, built alongside the firmware engineers who make them.

The Role

As a Senior Full Stack Engineer, you will:

• Own the design and delivery of full-stack web applications end to end, holding the plans and flagging risk early.
• Write clean, durable code across the web stack, and support the native mobile side when needed.
• Make AI-assisted tools a natural part of how you write, review and ship, and set the standard for the team.
• Mentor engineers, run sharp code reviews, and keep the quality bar high.
• Partner closely with your product manager on constraints and tradeoffs, without owning the roadmap yourself.
• Champion testing, CI/CD and deployment, and keep what you ship fast, secure and reliable.

About You

• You have 5+ years of professional software development, most of it full stack.
• You know a modern frontend framework well (React, Vue, Angular or SvelteKit). The team is on SvelteKit; strong experience elsewhere transfers, so it's preferred rather than essential.
• You're strong on the backend with TypeScript and Node.js, comfortable with serverless like AWS Lambda, and solid across SQL, NoSQL and AWS.
• AI-assisted workflows such as Claude Code or Copilot are already part of your daily practice, not occasional use.
• Your architecture fundamentals are sound and your debugging instincts are sharp.
• One of these fits you: a senior full-stack engineer from a product-led startup, an engineer from a hardware or connected-devices company who has worked with firmware teams, or a strong generalist who has put AI-assisted development at the centre of how they build.
• You're based in the San Francisco Bay Area and comfortable with a hybrid pattern.

The role pays a competitive base plus a potential equity grant, and the team is keen to move quickly. If reducing waste through beautifully built technology sounds like a mission worth your time, and you want to do it on a team where AI-assisted development is simply how the work gets done, apply now or send your CV directly to will@inventurerecruitment.com.
