Senior Full Stack Developer, CoLab Software

• This is a role for someone who likes difficult problems and meaningful ownership
• We’re looking for someone who enjoys understanding the full system — from infrastructure and services to the customer experience sitting on top of them
• You’re a strong backend engineer who’s comfortable contributing across the stack when needed
• You care about building reliable systems, but you also understand that great software only matters if it solves real customer problems
• You know how to balance speed, scalability, and maintainability without becoming dogmatic about any of them
• You enjoy owning problems end-to-end
• You’re curious about both systems architecture and product experience
• You communicate clearly and collaborate well across disciplines
• You hold a high technical bar while staying pragmatic and low ego
• 7+ years of experience building production software applications
• Strong backend development experience with modern languages such as Python and Javascript
• Experience building and maintaining APIs, distributed systems, and cloud-based applications
• Frontend experience with modern frameworks such as React and TypeScript
• Database experience with Postgres and DynamoDB
• Strong understanding of system design, scalability, and software architecture
• Experience working with relational and/or distributed data systems
• Ability to communicate technical concepts clearly across technical and non-technical audiences
• Comfortable operating in fast-moving environments with evolving priorities
• Frequently cited statistics show that people who identify with historically marginalized groups are likely to apply to jobs only if they meet 100% of the qualifications. We encourage you to help us break that statistic and apply even if you don’t meet every single qualification—your potential is what matters most to us

Desirable

• We’re looking for a Senior Full Stack Developer who naturally gravitates toward backend systems and infrastructure, but enjoys owning product experiences end-to-end
• At CoLab, full stack developers are deeply involved in shaping the product — not just implementing tickets
• You’ll work closely with Product, Design, AI, and fellow developers to solve complex technical problems that directly impact how engineering teams collaborate and make decisions
• Depending on the team you join, your work could involve building scalable APIs, improving system reliability, designing data-heavy workflows, integrating AI-powered capabilities, or developing intuitive frontend experiences for highly technical users
• The work is often ambiguous. Priorities evolve as we learn
• You’ll be expected to make thoughtful technical decisions, communicate clearly, and move work forward without waiting for perfect direction
• Some developers prefer staying narrowly specialized. That’s not this role
• Design, build, and maintain scalable backend services, APIs, and data systems
• Contribute to frontend application development using modern web technologies
• Collaborate cross-functionally with Product, Design, AI, and Engineering teams to ship high-impact product improvements
• Improve system reliability, observability, performance, and developer tooling
• Help shape technical direction, architecture decisions, and engineering best practices
• Investigate and resolve complex production issues across the stack
• Prototype quickly, gather feedback, and iterate based on customer and business needs
• Mentor developers through collaboration, code reviews, and technical discussions
