Job description

Senior Full Stack Software Engineer
Our client is looking for an experienced software engineer with a founder mindset to take a critical role in our rapidly growing early-stage startup. We believe software will be built 10x faster with teams leveraging the perfect combination of AI agents and collaborative tools. The platform we've built makes this future vision a reality, leading our company to an inflection point of growth. This role is an opportunity to join us early as we prepare to scale up in our market.

Responsibilities

  • Be a critical part of technical and product roadmap, we expect all of our engineers to be act like owners of the business, making decisions with a founder-like mentality

  • Build products across our stack (using Typescript, Node, and more) that enable our customers to build web apps 10x faster

  • Embrace our AI-first culture at every level. Find creative and novel ways to leverage AI at every part of the stack, from the React designer AI, to our network of asynchronous development agents, and for our own development processes

  • Collaborate directly with our team and customers to ship high leverage features, while iterating as fast as possible

  • Have a blast working at a quickly growing startup!

Looking for someone who:

  • Bachelor's Degree or equivalent experience

  • Has professional experience building full-stack applications (at least 4 years of professional full-time development experience, React experience a plus)

  • Is extremely talented and good at what you do (You execute complex tasks in half the time of your peers)

  • Has professional experience building and owning production-grade products in real life (not pet projects or projects for clients)

  • Has a very product and customer focused mindset

  • Has been bitten by enough code quality and maintenance issues in production codebases/systems to be opinionated on how they should be built

  • Is self-driven and can roll with the punches in a fast-paced environment where priorities and requirements may change frequently

Bonus points if you:

  • Are an ex-founder OR worked at an early-stage startup previously (Series A or earlier)

  • Have an eye for visual design (or past experience in product design, Figma, etc)
