Staff Software Engineer, Platform
Luminai
Staff Software Engineer Working On Platform
As 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 Do
Design and maintain the core frameworks, libraries, and shared packages that product engineers build on every day
Own developer experience end to end, including local dev environments, build systems, CI/CD, test infrastructure, and time-to-first-commit for new hires
Build and maintain the tooling that keeps quality high without slowing anyone down: linters, formatters, static analysis, codegen, and automated checks
Find and remove the bottlenecks in how we ship, then re-architect foundational abstractions to hold up as the team and the product scale
Lead core technical initiatives that set the quality bar in the codebase
Define and scale experimentation, monitoring, reliability, and observability for production systems
Drive improvements to the core Luminai IDE to deliver a great experience for end users
Set sane defaults for how the platform handles access control, secrets management, and authentication, so the systems others build on are safe without extra effort
What We're Looking For
8+ years as a software engineer, including zero to one projects you drove from scratch
Track record of shipping high-quality code on hard problems
Experience building internal frameworks, libraries, or developer tooling that other engineers depended on, and a real interest in making them better
Direct experience designing high performance backend systems in production, with judgment about the architectural trade-offs involved
Working 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)
Bonus
Familiarity with frontend foundations (JS toolchain, bundlers, build systems). Not required, but useful for platform work that reaches into the client
