Senior Full Stack Engineer

Who we are:

Hernandez Apps is a 15-person team running a niche online store for vintage audio parts. Our audience is small but loyal: about 40,000 newsletter subscribers who actually open it. Experiments run constantly, and most product decisions follow A/B test results.

What this job is:

This role opened up because a team member is relocating. You'll join a team of four engineers shipping weekly to a product used by operations staff and customers. Hybrid: two days in the office in San Jose, the rest from home.

What you'll do:

• Create and maintain REST or GraphQL endpoints
• Help junior developers get unstuck through pairing and review
• Turn wireframes and Figma mockups into working, responsive screens
• Refactor older code when you touch it rather than working around it
• Integrate third-party services such as Stripe, Twilio, SendGrid or Auth0
• Write automated tests at the unit, API and browser level
• Investigate bugs reported by support and fix them at the right layer

About you:

• 5+ years of full stack development experience
• Ability to work with little supervision and ask questions early
• Strong JavaScript or TypeScript plus experience with React, Vue or Angular
• Familiarity with Git, code review and CI pipelines
• Server-side experience in Node.js, Python (Django, FastAPI) or C# (.NET)

Pluses:

• Prisma, TypeORM or SQLAlchemy
• Some exposure to React Native

Pay and benefits:

Salary: $220,000 - $245,000/year

• Profit sharing
• Vision insurance
• Free parking
• Referral program
• Three weeks of PTO to start
• Professional development budget

Start: Immediately.
