[Remote] Senior Full Stack Engineer

Remote, USA Full-time Posted 2026-06-16

Note: The job is a remote job and is open to candidates in USA. Improbable is a company focused on building and scaling AI and Web3 ventures. They are seeking a Senior Full Stack Engineer to design and build production-grade products, including consumer apps and developer technologies, while owning the full lifecycle from prototyping to deployment.

Responsibilities

  • Design and build production-grade products end-to-end—back-end through UI—across consumer apps, developer-facing technologies and internal platform tooling
  • Build the high-performance back-ends and services these products depend on
  • Create developer technologies—SDKs, APIs, CLIs, libraries and starter kits—that make the platform easy to build on
  • Build internal tooling and platform infrastructure that raises the velocity of the whole team
  • Work self-directed: watch the ecosystem and the team's needs, spot gaps and propose and build what moves things forward
  • Work with DevRel, Marketing and BD so what you build lands with users and developers and fits go-to-market

Skills

  • Strong TypeScript across the full stack—this is the core of the role and our app stack
  • Some Golang where it fits
  • Build high-quality, production-ready frontends
  • Strong back-end engineering—APIs, services and the data layer behind them
  • Genuine interest in crypto and on-chain products
  • Strong ownership and self-direction—you generate ideas, not just execute them
  • Able to turn the dial: prototype fast and loose to prove a feature out, then shift into steady-state mode to harden what's worth keeping—tests, edge cases, reliability
