Lead Software Development Engineer - Infrastructure

Required

• Deep technical leadership experience — you've owned architectural strategy for high-scale, distributed systems, made the hard calls, and built the judgment that comes from living with the consequences.
• Expertise in large-scale data processing (Spark or a similar distributed framework), and the ability to explain the "why" behind an architectural choice, not just defend the what.
• Real fluency with AI-assisted and agentic ways of working. You already build, debug, and operate systems with LLMs and agent tooling as part of your process — this isn't a skill you're bolting on; it's how you work now. This is to say that, with the judgment you have, you can point at infrastructure and developer tooling and move fast.
• A love of learning and the ability to ramp up quickly on new stacks. We build in Clojure — we care far more about your ability to apply deep architectural principles to a new language than about prior Clojure experience.
• A demonstrated history of mentorship: you've coached senior engineers and built technical practices that outlast any single project.
• Comfort translating technical trade-offs into outcomes that serve the business and the platform's long-term health, working across a wide range of partners to get there.
• The ability to turn ambiguity — company-level strategic uncertainty, competing priorities, an unclear problem — into a concrete, executable engineering plan. People come to you when something's genuinely hard, and you cut through the complexity fast.
• Amperity’s work model operates on four in-office days each week and one designated remote workday on Wednesdays. We value the collaboration, connection, and learning that come from working together in person.
