About The Role

Join a product-focused engineering team at a bootstrapped AI platform studio building tools that bring AI to the heart of the SME sector. As a Senior Full Stack Engineer, you'll own complex architectural challenges — from large-scale data synchronisation to secure sandbox infrastructure — helping scale the platform to its next major milestone.

What You'll Do

• Own the most complex architectural problems across the platform, including multi-terabyte data synchronisation 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 synchronise and index terabytes 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 for fast custom integrations so new systems can be connected in hours.
• Collaborate on technical roadmaps and align on architectural decisions with the development team.
• Debug production incidents, identify root causes, and implement durable fixes.
• Mentor junior engineers and drive code quality through thorough, constructive reviews.
• Continuously improve development processes and engineering standards.
  
  

What We're Looking For

• 7+ years of professional software engineering experience.
• Strong hands-on proficiency with React, TypeScript, PostgreSQL, Docker, and CI/CD pipelines.
• Experience with tRPC or an equivalent type-safe API communication framework.
• Experience with Kubernetes and modern container orchestration at scale.
• Proven track record designing and scaling complex software architectures for high-growth products.
• Experience synchronising large datasets, handling high-volume LLM/API call processing, and building secure multi-tenant systems.
• Experience designing and implementing secure, multi-tenant sandbox environments.
• Strong sense of product ownership with genuine attention to user experience.
• Enthusiasm for mentoring engineers and actively shaping engineering culture and standards.
• Comfortable moving quickly and learning in a fast-paced environment.
