Senior Full Stack Engineer
About the Role
This is a senior engineering role on a product-focused team building a secure, scalable AI platform for the SME sector. You will own complex architectural challenges end-to-end, helping grow a platform that already serves a large and rapidly expanding user base across hundreds of companies.
What You'll Do
Own the most complex architectural problems on the platform, including multi-terabyte data synchronization and secure sandbox infrastructure.
Architect, build, and ship high-quality full-stack features using React and TypeScript, with a focus on long-term scalability and UX.
Design and implement systems to synchronize and index large volumes of client data while enforcing strict permissions.
Build infrastructure to process millions of LLM calls per month with high reliability and security.
Implement scalable, secure code sandbox solutions capable of spawning thousands of sandboxes per day.
Create base infrastructure and tooling for fast custom integrations so new systems can be connected quickly.
Collaborate on technical roadmaps and align on architectural decisions with the broader development team.
Debug production incidents, identify root causes, and implement durable fixes to keep the platform stable.
Mentor junior engineers and raise the bar through constructive, thorough code reviews.
Continuously improve development processes, code quality standards, and overall team performance.
What We're Looking For
7+ years of professional software engineering experience with a strong full-stack background, including clearly demonstrated frontend work.
Production experience with React, TypeScript, PostgreSQL, Docker, and CI/CD pipelines.
Hands-on experience with tRPC, Kubernetes, and modern frontend tooling.
Proven ability to design, scale, and maintain complex software architectures for high-growth products.
Experience operating large-scale, reliable, and secure systems such as large dataset synchronization, high-volume API or LLM processing, or secure multi-tenant infrastructure.
End-to-end ownership of substantial initiatives from conception through delivery and ongoing operation.
Motivation and ability to mentor engineers, conduct thorough code reviews, and shape engineering standards.
Strong product ownership mindset with attention to user experience and long-term product success.
