Staff Engineer (Full Stack)

The Opportunity

We’re a small, dedicated team with big ambitions — and we’re looking for a Staff Engineer (Full Stack) who’s ready to help us scale fast and think even bigger.

You won’t just ship features — you’ll help define the architecture, culture, and velocity of our product development team. You’ll be hands-on in the codebase, leading by example, and helping Capio evolve into a high-performing, scalable platform used by thousands.

If you love the thrill of building fast, owning outcomes, and influencing the direction of a company from the ground up, this is your place.

What you’ll be doing every day:

• Lead full-stack development efforts — from designing scalable backend systems to crafting seamless front-end experiences.
• Partner with leadership to shape the product direction and technical roadmap.
• Collaborate with engineering leaders to make critical architectural decisions around performance, scalability, and reliability.
• Mentor and collaborate with a team of dedicated engineers, fostering speed and quality in equal measure.
• Build clean, efficient, and maintainable code across the stack (React, Node.js, TypeScript,, AWS — or whatever gets the job done).
• Thrive in a fast-paced startup environment where initiative, creativity, and execution matter most.

What you bring to the table:

• A builder’s mindset — bias toward action, curiosity, and constant iteration.
• Strong product sense — you care about user experience as much as elegant code.
• Great communication skills. (Yes, everyone writes that - but we really mean it.)
• Demonstrated ownership and pride in the quality of the software you work on, and the way that it succeeds in meeting the needs of its users
• Knowledge of a variety of programming paradigms and languages, design patterns, tech stacks and frameworks - and the trade-offs entailed in choosing among them
• Ability to explain and defend an informed opinion while maintaining an open mind
• Experience with engineering practices and processes which promote incrementalism, frequent delivery and tight feedback loops - without sacrificing quality

Ideally, you also have experience with some of:

• Node.js, Typescript or Javascript, React.js
• AWS services e.g. S3, Dynamo Db, Lambda
• AI/ML and data products and building AI-powered products end to endData storage systems e.g. relational databases (Postgres, Redshift), ORM libraries, document-based data stores (Dynamo DB)
• Test automation including unit testing, integration testing and end-to-end testing
• Knowledge on integration patterns, concepts and implementation
• Dev Ops, Observability, Infrastructure as Code
• Data engineering (e.g., data modeling, pipelines, orchestration, denormalization/transformations)
• AI tooling (e.g., model integration and serving, vector databases/embeddings, prompt tooling, evaluation/observability)
• Designing and delivering production-grade AI features and systems

Why join Capio:

• Impact that matters: International education affects millions of students worldwide, and you’ll play a key role in shaping its future.
• Autonomy and ownership: Your ideas won’t just be heard, they’ll drive our growth strategy.
• Have a massive impact on the company’s direction and growth from day one.
• Fast-paced momentum: We’re scaling quickly, and you’ll be at the center of it.
• Mission-driven team: Work alongside people passionate about innovation, education, and making a global difference.
