Software Engineer, AI Coding Tasks (Contract)

Headquarters: New York City URL: https://sanctuary.computer We are hiring a Head of Technology for the garden3d creative collective, to lead engineering at Sanctuary Computer and garden3d in the era of agentic computer code. Original job posting link About garden3d We are worker owned creative collective, innovating on everything from brands and IRL communities to IoT devices and cross platform apps. We share profit, open source everything, spin out new businesses, and invest in exciting ideas through financial and/or in-kind contributions. Our client roster includes Google, Stripe, Figma, Hinge, Black Socialists in America, ACLU, Pratt, Parsons, Mozilla, The Nobel Prize, MIT, Gnosis, Etsy & Gagosian. We’re the software team behind innovative products like The Light Phone & Mill, and we operate a global, decentralized community space collective called Index Space. We think of our garden3d as collective for creative people, prioritizing a happy, talented, and diverse studio culture. We work on projects that bring value to our world, and we balance deep care for the work we do with a genuine curiosity about life outside of our jobs. Sanctuary Computer - Development At Sanctuary Computer we’re building a different type of technology shop – one that prioritizes close collaboration between the client and the craftsperson. Our projects range from design-forward websites, to robust web apps, to native mobile development. XXIX - Design When we started XXIX in 2013, we set out to create a different kind of design studio and we’ve thrived because we continually ask what a creative practice can be. We’re building a radically different kind of organization that values autonomy, growth, transparency, and shared responsibility. Index - Community Index is network of physical spaces all around the world, Index provides space for the exchange of knowledge and tools. We nurture trust within the creative community through generosity and abundance of ideas and care. garden3d TK — Media At garden3d, we’re in the early stages of building an experimental media company exploring emerging themes related to the evolving landscape of technology, design and culture. We aim to monetize this outlet, publish books, produce screenplays, and release music. Plus, our partner organizations Lightphone Mill IngredientAI ⛰️ The Head of Technology Role The garden3d Head of Technology has one mandate: everything we build works, holds up in production, and gets built the smartest way available to us. We are a house of brands - Sanctuary Computer (development), XXIX (design), Index Space (community), USB Club (digital community), and the garden3d umbrella itself - and a lot of what all of them ship runs on software we wrote. Working in close partnership with our founder & president Hugh Francis, this person sets the engineering standard, and builds the culture that holds it. You can be based anywhere. A lot of our people are in New York and there's some gravity here, but we already work across timezones and we would happily hire in Europe, Singapore, Chicago, or wherever you are. If you're the right person, we want to hear from you. This role works with studio leads, developers, designers, project managers and clients across every garden3d vertical. This person can move between a Rails migration, a Next.js app, a firmware release plan and an agent loop in the same week, and raise the bar on each of them. They span all of garden3d, but their home base is Sanctuary Computer, where roughly 70% of their time goes. Our development studio is where the engineering standard gets set, and where it either holds or slips: architecture, code review, estimation, and the hardest technical calls on our biggest projects. The other 30% goes to garden3d's broader technology story: how we ship product for USB Club, build with agents across the collective, which tools and platforms we bet on, and what we build for ourselves. They are also how we get better people. Our work is only as good as the engineers making it, so this person hunts for exceptional talent, sells them on us, and sets them up to do the best work of their careers. The ideal candidate looks at a worker-owned collective with four studios, an open P&L and clients like Google, Stripe, Brooklyn Museum and The Nobel Prize, and sees an engineering practice they can propel among the best in the world. Responsibilities & Mandates ️ Systems that hold up We build web apps, native apps, data pipelines, content platforms and connected devices for clients who can't afford for them to fall over. This person has engineered complex systems for a long time, and it shows in the architecture they draw before a line is written. They own the technical blueprint on our most important projects, and they make the hard calls on the rest: what to build, what to buy, and what to leave out. All in on agentic development The way software gets built changed, and we intend to be ahead of it. This person is already deep in it: loop engineering, agents running against evals, agents that open their own PRs, and the guardrails that make all of that trustworthy. They make agentic development the default way Sanctuary Computer works, and they can tell the difference between a demo and a system a team can rely on. Practical engineering We strongly prefer convention over configuration, boring technology, and platforms that let a small team ship a lot. TypeScript is the default language, Rails and Phoenix handle what they're best at, and we'd rather deploy to a platform like Render or Heroku than run our own infrastructure. This person practices value engineering: the simplest thing that works, built well, at a cost the client is glad to pay. Code quality at Sanctuary Computer Sanctuary Computer is where our engineering standard lives, so this is where most of their energy goes. They set what good code review looks like, keep our senior developers sharp on architecture and quality, and make sure that bar holds without slowing the team down. Hiring and empowering the very best They are a magnet for exceptional engineers. They know where to find them, how to convince them, and how to give them enough room to do their best work while still holding them to the standard. People who work for this person should get visibly better, and should say so. Estimation, scoping and delivery They make sure our teams can reliably estimate and story point the work ahead, and that we deliver at a pace that meets the dates we promised and protects our margins. When an estimate is wrong, they find out why and fix the process. The technical voice in new business Our clients include Google, Stripe, Figma, Mozilla and The Nobel Prize. This person joins new business calls as the trusted technical consultant, scopes the work, writes the technical side of proposals, and can explain a hard tradeoff to a client's CTO and their CEO in the same meeting. Hardware sense We're the software team behind The Light Phone and Mill, so a good share of our work touches devices. This person doesn't need to be a firmware engineer, but they understand how hardware works, where it constrains the software, and how to plan a project that spans both. The garden3d technology story Across the collective, they decide which tools and platforms we bet on, how every studio uses agents, and which internal tools are worth turning into products. When someone at garden3d asks "how should we build this?", this person has the answer, or knows who does. Culture They model garden3d's values of partnership, curiosity, and accountability. The engineers they lead do the best work of their careers here, because the feedback is honest, the recognition is earned, and the craft rubs off Special Projects In addition to day to day responsibilities, here’s an idea of some of the projects this role may spearhead or support in coming years → • Making agentic development the default way Sanctuary Computer builds, with loops and evals the whole team trusts • Setting the shared technical conventions every garden3d studio builds from • Landing the kind of flagship engineering engagement that changes what people think we do • Hiring the next generation of the engineering team, across every garden3d studio • Turning the internal tools and agents we build for ourselves into products • Partnering with the Head of Design so our own studio websites are as well engineered as they are designed Qualifications This is a great opportunity for someone looking to make a significant impact in a growing, dynamic company. Based on the responsibilities of this role, we think the right candidate has the following experience and skills: Must have: • 12+ years building software, at least three of them leading engineers inside a studio, agency, startup or founder-led company • Deep experience engineering complex systems, shipped and run in production: distributed services, data pipelines, multi-platform pr...
