Job Description

As a Senior Software Engineer on the 3P Search team, you will lead the design and evolution of the systems that connect Axon Records to external law enforcement databases and third-party partners. This team operates at critical system boundaries. We own secure, compliant integrations with NCIC and other state and federal databases, as well as partner-facing APIs that expose Axon Records data to CAD vendors and internal Axon systems. These systems must be correct, reliable, auditable, and resilient in the face of external dependencies. In this role, you will take ownership of complex backend systems that handle sensitive search workflows and partner integrations. You’ll translate regulatory, operational, and product requirements into well-architected solutions, ensuring that reliability and compliance are built in from the start - not retrofitted later. As a senior engineer, you are expected to raise the technical bar for the team—leading system design, anticipating failure modes, improving observability and operational rigor, and mentoring engineers as we scale Axon Records’ external search and integration capabilities.

Job Responsibility

  • Own the design and implementation of complex backend systems supporting NCIC search and third-party integrations
  • Design and evolve partner-facing Records APIs, including versioning strategies, data models, authentication, and contract stability
  • Lead system design discussions, clearly articulating tradeoffs across reliability, scalability, compliance, and maintainability
  • Anticipate and mitigate failure modes across distributed systems with external dependencies (timeouts, retries, idempotency, backpressure, etc.)
  • Improve observability, auditability, and operational tooling for search workflows and partner integrations
  • Own the design and delivery of end-to-end search workflows, spanning backend systems for NCIC and third-party integrations and frontend applications that initiate and display search results
  • Coordinate technical work across engineers and partner teams to deliver cohesive, end-to-end integration solutions
  • Set and uphold a high technical standard through thorough code reviews, design reviews, and a focus on correctness and operational excellence
  • Participate in and improve on-call practices
  • lead incident reviews and drive systemic reliability improvements
  • Mentor engineers through technical guidance, pairing, and constructive feedback
  • Contribute to planning and execution of projects spanning multiple services, APIs, or integration surfaces

Requirements

  • 9+ years of professional software engineering experience
  • A bachelor’s degree in Computer Science, Engineering, or a related technical field (or equivalent practical experience)
  • Demonstrated experience owning full stack systems end-to-end in production environments
  • Experience designing and operating complex, cloud-based distributed systems in production
  • Strong system design skills, including the ability to reason clearly about reliability, consistency, compliance, and external integration tradeoffs
  • Experience creating and evolving APIs or services consumed by external partners or other engineering teams
  • Demonstrated ability to operate effectively in ambiguous or high-risk system boundaries and drive clarity through technical leadership
  • Experience leading technical projects and coordinating work across teams
  • Strong collaboration and communication skills, working effectively across engineering, product, compliance, and partner teams

Nice to have

  • Experience building highly reliable, audit-heavy systems with strict correctness requirements
  • Experience integrating with enterprise third-party platforms
  • Experience improving operational tooling, observability, and incident response processes
  • Experience contributing across the full stack when needed

What we offer

  • Competitive salary and 401k with employer match
  • Discretionary paid time off
  • Paid parental leave for all
  • Medical, Dental, Vision plans
  • Fitness Programs
  • Emotional & Mental Wellness support
  • Learning & Development programs
