Role Description As a Principal Software Engineer, you will be a technical leader and individual contributor who sets the bar for engineering excellence across the organization. You’ll design and deliver complex, high-impact systems, mentor engineers, and partner closely with product, design, and executive leadership to shape the technical roadmap. This is not a people-management role, but a deeply technical position for software developers who still love writing code while influencing architecture and strategy at the highest level. What does a typical day look like for the Principal Software Engineer? - Architect, build, and own large-scale distributed systems, containerized applications, services, and platforms that are reliable, performant, and maintainable. - Lead the most technically challenging and business-critical projects end-to-end. - Define and evolve technical strategy, standards, and best practices across the entire engineering organization. - Drive cross-team initiatives (e.g., performance, reliability, security, and developer productivity). - Mentor and level-up engineers through design reviews, pair programming, and technical guidance. - Collaborate with product and business leaders to translate ambiguous problems into clear technical solutions. - Identify and mitigate technical debt while pushing the boundaries of what’s possible. - Stay ahead of industry trends and bring innovative ideas into the company. Qualifications - U.S. citizenship and ability to obtain a government clearance. - 10+ years of progressive professional software engineering experience. - At least a bachelor's degree in computer science or a related field (or equivalent experience). - Proven track record of designing and shipping large-scale, highly available microservices-based applications using modern tech stacks (i.e. Nuxt, Vue.js, Python). - Strong experience leveraging AI tools and frameworks to develop and manage MCP servers, integrate AI capabilities to drive significant productivity gains, and implement appropriate oversight, governance, and quality controls. - Strong experience with AWS solutions and managing containerized workloads using Kubernetes. - Proven expertise with relational database design & architecture (MSSQL, Postgres, Redis). - Deep expertise in one or more domains: backend systems, infrastructure, data platforms, machine learning infrastructure, high-performance services, etc. - Strong computer science fundamentals (algorithms, data structures, system design). - Experience leading complex technical projects across teams. - Excellent communication skills - you can explain complex technical concepts to engineers and non-engineers alike. - Demonstrated ability to balance speed and quality; you ship fast without sacrificing long-term maintainability. Requirements - Experience scaling systems. - Background in startups or high-growth environments. - Experience with Rust. - Hands-on experience implementing applications that use PKI authentication. - Experience with Physical Access Control Systems (PACS). - A history of raising the bar at previous companies (i.e. open-source contributions, published technical writing, or conference talks). Benefits - Health, dental, and vision coverage. - Health Savings Account plan. - 401(k) plan with a generous employer match. - Unlimited PTO policy. - Seven company holidays. - A week-long break at the end of each year.
