Principal Software Engineer, Data Infrastructure

Required

• 8+ years of experience building large-scale backend/distributed systems and shipping high-quality systems to production. Strong preference for candidates who have experience with building developer platforms.
• 4+ years acting as a tech lead: setting direction, driving execution, and growing engineers at multiple levels
• Deep proficiency in Go or a similar compiled language (Go strongly preferred). Experience with CQRS & Event Sourcing is a plus
• Experience with NoSQL databases at scale (DynamoDB, Cassandra, or similar)
• Experience with or strong interest in AI/ML platform integration — pipelines, agentic workflows, HITL workflows or similar
• BA/BS in Computer Science, Engineering, or a related technical field — or equivalent experience
• A hands-on technical leader. You can zoom out to own the architecture and zoom in to write the hard code. You don't choose between leading and building — you do both.
• A platform thinker. You design for reuse, velocity, and reliability. You understand that your customers are other engineering teams, and you build with them in mind.
• Comfortable with ambiguity. You thrive on open-ended, gnarly problems. You can break them down, build alignment, and drive them to resolution — without waiting for perfect requirements.
• A team-player & multiplier. You are collaborative & strive to make everyone around you better — through rigorous code & architecture reviews, clear technical communication, and a genuine investment in the growth of the people you work with.
