This role starts as a hands‑on senior engineer and technical lead, with a clear path into broader engineering leadership as we scale.
The Role You’ll operate as a senior individual contributor while providing technical leadership to a small, growing team. You’ll partner closely with the CTO on architecture, product delivery, and team development, without stepping away from the code.
As the company grows, this role is expected to evolve into a formal leadership position with increasing scope across technical direction, hiring, and team development.

Provide day‑to‑day technical guidance and mentorship to engineers
Collaborate with the CTO on architecture and system design decisions
Contribute to scalable, performant, and maintainable systems
Establish and uphold engineering standards, best practices, and documentation
Support hiring and onboarding as we grow the team
Leverage modern tools, including AI, to improve development efficiency and workflows

Backend: Go (Golang)
Tooling: Vite, SWC, Jest, ESLint, Prettier
Styling: Sass, CSS Modules
Database: PostgreSQL (Kysely)
Infrastructure: AWS
We prioritize performance, type safety, and developer experience across the stack.
What We’re Looking For Core Experience
Strong full-stack development experience with modern JavaScript/TypeScript and backend systems
Proven ability to own and ship production features end‑to‑end
Experience mentoring or guiding other engineers (formal or informal)
Solid understanding of scalable architecture and engineering best practices
Strong communication skills and ability to collaborate cross‑functionally
Nice to Have (Not Required)
Experience with Go or interest in learning it
Exposure to fintech, blockchain, or regulated environments
Startup or high‑growth company experience
Experience with secure application design or infrastructure
