We invest in continuous learning, value ownership, and encourage engineers to work closely with both product and business stakeholders. Our team is distributed, with hubs in major global tech centers.\nRole Overview\nWe’re looking for a Principal Engineer who wants both technical depth and product impact. This is not a “pure architect” role; you’ll be in the code, shaping systems, and setting the bar for engineering quality.\nYou’ll own major initiatives end to end: define the problem, design the architecture, choose the technologies, drive the implementation, and shepherd systems safely into production. You’ll be trusted with high autonomy and expected to turn ambiguous business needs into clear, scalable solutions.\nKey Responsibilities\nLead end-to-end delivery of product and platform initiatives, from early problem framing through deployment and ongoing support.\n\nEstablish technical direction that balances immediate delivery with long-term scalability.\n\nDesign and implement robust systems across both frontend and backend layers.\n\nCollaborate closely with cross-functional partners while maintaining strong individual ownership.\n\nMake informed trade-offs between speed, maintainability, and performance.\n\nContribute high-quality code and set standards through thoughtful reviews.\n\nNavigate ambiguous problem spaces and turn incomplete requirements into concrete solutions.\n\nIntroduce pragmatic engineering practices suited for a fast-moving environment.\n\nContinuously improve system performance, reliability, and security as usage grows.\n\nTake responsibility for production systems, including monitoring, incident handling, and post-incident analysis.\n\nDocument architectural decisions and technical approaches to support future team growth.\n\nProvide guidance and mentorship to other engineers as the team expands.\n\nEvaluate tooling and infrastructure decisions, including build-versus-buy considerations.\n\nRequirements\nExtensive experience (10+ years) in software development with a strong breadth across frontend and backend systems.\n\nDemonstrated ability to lead and deliver complex initiatives independently in high-growth or startup environments.\n\nDeep expertise in JavaScript and TypeScript.\n\nStrong experience with modern frontend frameworks such as React or equivalent.\n\nSolid backend experience, particularly with Node.js and Go.\n\nStrong database knowledge across relational and non-relational systems, including performance optimization.\n\nExperience building APIs (REST and/or GraphQL) and designing service-oriented architectures.\n\nFamiliarity with major cloud providers and distributed system patterns.\n\nHands-on experience with CI/CD, infrastructure automation, and production operations.\n\nExperience working with containerization and orchestration tools.\n\nExposure to event-driven architectures and messaging systems.\n\nStrong system design skills and an understanding of trade-offs in evolving products.\n\nAbility to operate effectively with limited guidance and shifting priorities.\n\nClear communication skills, especially when bridging technical and business contexts.\n\nExperience leading migrations, refactors, or platform evolution is a strong asset.\n\nSuccess Indicators\nYou deliver critical systems independently that perform reliably in production.\n\nYour architectural decisions enable both rapid development and future scalability.\n\nEngineering output improves due to clarity, ownership, and reduced friction.\n\nProduction environments remain stable, and issues are resolved efficiently when they arise.\n\nYou become a trusted technical authority within the team.","description_format":"text","description_chars":3727,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Continuous
