About The Position

Fazeshift is hiring its first senior engineer. You’ll be a technical cornerstone of the product — shaping architecture, shipping end-to-end features, and setting the bar for engineering quality as we grow. This isn’t a role where you maintain what others built; you’ll have significant ownership over what we build and how.

Requirements

5+ years of professional software engineering experience, with meaningful time spent owning production systems where correctness and uptime matter (payments, fintech, identity, fraud, infrastructure, or similar high-stakes domains)
Strong TypeScript skills across the full stack
Comfort with modern React patterns and Next.js Pages Router
Experience with relational databases and ORM-based schema management (Prisma or similar)
Solid instincts around API design, system reliability, and developer experience
Experience at an early-stage startup, or a strong desire to operate in that environment
Track record of mentoring engineers and raising the engineering bar on a team
High ownership mindset — you don’t wait to be told what needs to be done

Nice To Haves

Hands-on experience with Inngest, or other event-driven/workflow orchestration tools
Experience scaling a SaaS product from early users to meaningful ARR
Background in fintech, revenue operations, or B2B SaaS

Responsibilities

Design and build full-stack features across the Next.js frontend and backend API layer
Lead end-to-end on schema design, migrations, and backfills across Prisma and MySQL, and design rollouts that are safe to deploy
Set the bar for engineering practices on the squad through system design reviews, incident response, runbooks, and observability
Mentor other engineers through code review and architectural guidance
Collaborate directly with founders on product direction and technical trade-offs
