About the Role
This is a senior engineering role at a bootstrapped AI platform studio focused on bringing AI tools to the SME sector. You'll join a small, product-focused engineering team building secure, scalable infrastructure and intuitive UX for a platform already used across hundreds of companies — with ambitious growth targets ahead.
What You'll Do
-
Own complex architectural challenges 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 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 for fast custom integrations, enabling new systems to be connected in hours.
-
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 maintain platform stability.
-
Mentor junior engineers and raise the bar through constructive, thorough code reviews.
-
Continuously improve development processes, code quality standards, and team performance.
What We're Looking For
-
7+ years of professional software engineering experience with React, TypeScript, PostgreSQL, and the surrounding ecosystem (Docker, CI/CD).
-
Proven track record designing, scaling, and maintaining complex software architectures for high-growth products.
-
Hands-on experience with tRPC or an equivalent type-safe API communication framework, Kubernetes, and modern frontend tooling.
-
Experience with relational data modelling and query performance optimisation in PostgreSQL.
-
Experience operating at scale: synchronising large datasets, handling high volumes of LLM/API calls, 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 and long-term product success.
-
A passion for mentoring engineers and actively shaping engineering standards and processes.
-
Comfortable learning quickly and thriving in a fast-paced, high-growth environment.
