Overview
Staff Software Engineer role at Axon. Axon is on a mission to Protect Life and is seeking a technical leader to contribute to Axon Assistant, helping shape the future of how public safety professionals interact with intelligent systems.
What You’ll Do
* Lead technical direction and architecture for key systems powering Axon Assistant across backend, mobile, and edge-device surfaces.
* Design and build high-performance, fault-tolerant services for AI feature delivery, real-time communication, and intelligent user interaction.
* Evaluate and integrate LLMs and other AI/ML models for production — ensuring safe, performant, and explainable applications of language technologies.
* Own complex decision-making processes, including model selection vs. deterministic logic, latency, data retention, cost, and user trust considerations.
* Collaborate with PMs, Applied AI teams, and UX engineers to align technology decisions with user experience and product strategy, ensuring fluid, contextual interactions.
* Write and review production code (Node.js, Python, or equivalent) and mentor engineers in high-quality engineering practices.
* Lead cross-functional technical investigations, root cause analyses, and high-risk launches with ownership and clarity.
* Bring order and momentum to ambiguous requirements while preserving long-term architectural health.
What You Bring
* 10+ years of software engineering experience, including 3+ years in Staff-level or equivalent roles.
* Proven experience designing and delivering complex backend systems, ideally in distributed or real-time environments.
* Hands-on experience building and deploying AI/ML-powered systems, especially with LLMs, NLP services, or multimodal interfaces.
* Deep understanding of cloud infrastructure, service reliability, and secure system design (AWS, GCP, or Azure).
* Advanced fluency in backend languages such as Node.js, Python, or Go, with a focus on scalable, testable design.
* Strong architectural thinking and judgment — ability to navigate ambiguity and drive consensus.
* Experience with real-world deployment constraints, including multi-region scaling, privacy compliance, and observability.
* Ability to influence, mentor, and lead across engineering boundaries without formal authority.
Nice to Have
* Experience building assistant-style interfaces or integrating LLMs in production settings.
* Background in regulated domains or high-trust environments (e.g., public safety, healthcare, financial services).
* Contributions to open-source AI tooling or relevant community work.
* Familiarity with on-device compute constraints, edge inference, or hybrid client/cloud architecture.
Benefits That Benefit You
* Competitive base salary and RSUs.
* Comprehensive pension plan with matching contributions.
* Private health insurance and cash plans.
