Principal Software Engineer, SOC Experience

Responsibilities

• Be the engineering face of the team and a trusted technical leader across the department. In cross-functional conversations with other engineering teams, product, or leadership, represent the team's technical perspective clearly and credibly. Drive alignment on key decisions.
• Balance technical rigor with pragmatism. Push back when taking a shortcut creates real risk, but also push back against over-engineering when the goal is discovery or prototyping. Make sound tradeoff decisions across requirements, reliability, performance, and cost.
• Keep the team moving. Break down ambiguous requirements into work that can actually be executed, surface and clear blockers before they become delays.
• Shape the team as well as the code. Give direct feedback, help engineers grow into solving harder problems, and model the kind of judgment and accountability expected.
• Raise the floor and the ceiling through code review, pairing on problems, and creating leverage through better patterns, tooling, and shared understanding.
• Shape how AI is built into the product. Design and ship agentic investigation capabilities that help analysts triage and report faster, with accuracy, safety, and auditability.
• Prototype through hard problems. Dig in first on uncertain challenges, derisk, prove out the approach, then hand it off clearly.
• Own the team's technical architecture and influence architectural direction across the system. Define long-term technical strategy for data models, interfaces, and contracts.

Requirements

• 15+ years of experience developing complex software products
• 8+ years of programming in Ruby on Rails
• BS or MS in Computer Science or Engineering, or equivalent experience
• Experience with AWS, Azure, or other public cloud environments
• Experience with relational databases such as Postgres and with in-memory datastores such as Redis
• Experience building production systems with LLMs, using agents, tools, evaluation, guardrails, and common, proven patterns
• Experience with AI coding tools, such as Claude Code
• Deep backend expertise and a track record of scaling production systems
• Solid frontend fundamentals (Hotwire, Turbo, and Stimulus), but able to reason outside that box
• Proven ability to build and maintain large, highly parallel systems and design for concurrency, throughput, and correctness under load

Nice-to-Haves

• Mentoring senior engineers
• Cross-functional collaboration with product, UX, and SOC stakeholders
