Sr. Software Engineer, Fullstack - Remote

This is a senior engineering role, but it's a genuine step up for someone ready to move beyond junior work. You'll own the design and delivery of large-scale systems that serve Fortune 100 companies and millions of employees daily. That scale, paired with real responsibility for architecture decisions, will accelerate your growth faster than most early-career paths.

Your day-to-day: design and build multi-tenant cloud services with a focus on availability and fault tolerance. You'll set engineering standards for the team, review work, and help other engineers level up. This is backend and frontend work — you'll touch the full stack and make decisions about how systems fit together.

You're a fit if you have solid fundamentals in backend and frontend development, can reason about distributed systems, and genuinely care about code quality. A portfolio or GitHub showing real projects matters more than any credential. You should be comfortable working remote and prefer clarity over hand-holding.
