Principal Software Engineer

• Partner with Product to uncover underlying user needs, challenge assumptions, and turn ambiguous problems into practical solutions. 

• Design and build intuitive interfaces, maintaining coherent workflows, and a consistent user experience as the product evolves. 

• Lead features and substantial refactors across the stack, understanding dependencies, and managing the consequences of changes beyond the immediate implementation. 

• Own the correctness and security of your work, including AI-assisted output, through meaningful testing and verification. 

• Improve resilience and observability so failures can be detected quickly, contained, and resolved efficiently. 

• Mentor engineers through collaborative problem-solving, technical guidance, and code review, developing their ability to work independently. 

• Drive improvements to architecture, tooling, and engineering practices that reduce complexity, shorten feedback cycles, and improve product quality. 

What You'll Bring 

• Strong hands-on experience building production applications with TypeScript, React, and Node.js. 

• Practical UX/UI design skills, supported by solid HTML and CSS fundamentals. You can explain how your design choices help users understand and complete their work. 

• Experience independently delivering complex features and substantial refactors in established codebases. 

• Sound data modeling and SQL skills, with an understanding of how changes affect stored data, calculations, and reporting. 

• Strong software engineering fundamentals, including data structures, algorithms, state, and memory behavior. You can reason about correctness and performance trade-offs and apply that understanding across languages. 

• Clear technical communication and experience helping other engineers develop their judgment. You can challenge a decision constructively and revise your own position when the evidence warrants it. 

Bonus Points 

• Experience developing and testing Rust applications. 

• Experience with systems or performance-sensitive development in languages such as C++, Go, C#, or Java, involving memory allocation, shared data, and copying costs. 

• Experience building interfaces with Tailwind CSS. 

• Experience translating security, data integrity, and compliance requirements into practical engineering controls, including work with SOC 2 or GxP-regulated systems and 21 CFR Part 11 where applicable.
