As a Senior Full Stack Engineer, you will own complex architectural challenges and help scale a platform already used by thousands of teams toward its next major growth milestone. Your work will directly shape the reliability, security, and user experience of a product with real business impact. WHAT YOU'LL DO

• Own the most complex architectural problems across 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 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 to enable fast custom integrations with new systems.
• Collaborate on technical roadmaps and align on architectural decisions with the development team.
• Debug production incidents, identify root causes, and implement durable fixes to keep the platform stable.
• Mentor junior colleagues 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 clear track record of full-stack work, including demonstrated frontend contributions.
• 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 systems: 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 operation.
• Genuine motivation to mentor engineers, conduct thorough code reviews, and shape engineering standards.
• Strong product ownership mindset with attention to UX and long-term product success.
• Comfortable learning quickly and thriving in a fast-paced, high-growth environment.
