Staff Software Engineer, Platform

Staff Software Engineer Working On PlatformAs a Staff Software Engineer working on Platform, you will play a foundational role in designing, implementing and spearheading the core platform development. The platform is used by organizations worldwide to deploy and scale executable AI automations in mission critical production environments. As a senior member of the engineering team, you are expected to have a strong proficiency in fundamentals of software engineering and exceptional ability to drive technical projects in ambitious technical environments. You will help define, architect and improve key system foundations that allows the overall engineering team to execute effectively and deliver a stellar platform experience for users within a high growth team.What You'll DoDesign and maintain the core frameworks, libraries, and shared packages that product engineers build on every dayOwn developer experience end to end, including local dev environments, build systems, CI/CD, test infrastructure, and time-to-first-commit for new hiresBuild and maintain the tooling that keeps quality high without slowing anyone down: linters, formatters, static analysis, codegen, and automated checksFind and remove the bottlenecks in how we ship, then re-architect foundational abstractions to hold up as the team and the product scaleLead core technical initiatives that set the quality bar in the codebaseDefine and scale experimentation, monitoring, reliability, and observability for production systemsDrive improvements to the core Luminai IDE to deliver a great experience for end usersSet sane defaults for how the platform handles access control, secrets management, and authentication, so the systems others build on are safe without extra effortWhat We're Looking For8+ years as a software engineer, including zero to one projects you drove from scratchTrack record of shipping high-quality code on hard problemsExperience building internal frameworks, libraries, or developer tooling that other engineers depended on, and a real interest in making them betterDirect experience designing high performance backend systems in production, with judgment about the architectural trade-offs involvedWorking familiarity with a modern infrastructure stack (Kafka, Kubernetes, or similar)Solid grasp of security fundamentals for backend and cloud systems (authN/authZ, secrets management, encryption)BonusFamiliarity with frontend foundations (JS toolchain, bundlers, build systems). Not required, but useful for platform work that reaches into the client
