Senior Full-Stack Engineer

Level: Senior

Experience: 5+ years

Location: Remote

Own features end-to-end across our client projects — from API design through to a shipped, production-ready interface.


What you'll do

Design and build full-stack features across React/Next.js front ends and Node.js or Java back ends

Own technical decisions on assigned client projects, from architecture through deployment

Review code from other engineers and set technical direction within your project team

Work directly with clients during scoping and delivery, not just internally

Mentor mid-level engineers on system design and code quality

What we're looking for

5+ years building production web applications end-to-end

Strong TypeScript and React experience, with comfort on the back end (Node.js, Java, or similar)

Experience designing APIs and data models from scratch, not just consuming them

Comfortable working directly with clients, not just behind a project manager

Track record of owning a feature or system from design through production

Nice to have

Experience with Next.js App Router specifically

Exposure to AWS or another major cloud provider

Consulting or agency background working across multiple client codebases
