Senior Software Engineer

TypeScriptReactNext.jsMySQLSF · Senior · Seed

About the Role

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.

What You’ll Do

  • 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

What We’re Looking For

  • 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 Have

  • 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

Our Stack

TypeScript · Next.js · tRPC · Prisma · Zod · Inngest · MySQL

What We Offer

  • Competitive salary and meaningful equity

  • Full benefits (medical, dental, vision)

  • Flexible PTO

  • Direct impact on product and company direction from day one
