About The Position

Join Axon and be a Force for Good. At Axon, we’re on a mission to Protect Life. We’re explorers, pursuing society’s most critical safety and justice issues with our ecosystem of devices and cloud software. Like our products, we work better together. We connect with candor and care, seeking out diverse perspectives from our customers, communities and each other. Life at Axon is fast-paced, challenging and meaningful. Here, you’ll take ownership and drive real change. Constantly grow as you work hard for a mission that matters at a company where you matter. Your Impact As a Staff Software Engineer on Axon's Real-Time Operations (RTO) team, you will make a direct impact on our mission to Protect Life. RTO builds the situational awareness software that emergency responders and security operations teams rely on in the moments that matter most, and the experiences they touch have to be fast, reliable, and trustworthy under real pressure. Fusus, our real-time crime center and operations platform, is growing fast: from local public safety agencies into the enterprise space, and from the US into international regions including the UK, Australia, and Europe. That growth means many market verticals, regulatory environments, and customer workflows converging on a shared platform. We need a technical leader who can define how we build client experiences that scale to millions of users across all of them. In this role you will own the client architecture and frontend foundations strategy for RTO. You will define how we develop, compose, and ship client experiences so that Axon can deliver unique, vertical-specific workflows at scale on a common foundation. You will reason from first principles about how the system should work, not just how it works today, and you will set the technical direction that lets feature teams move fast without fragmenting the platform.

Requirements

10+ years of professional software engineering experience, with a track record of technical leadership at the Staff or Principal level.
Bachelor's Degree in Computer Science, Engineering, or related field
A first-principles thinker who reasons about systems from the ground up rather than by analogy to what already exists, and who can frame the right long-term architecture amid ambiguity.
Proven experience designing and building systems that scale to millions of users, with depth that spans the full stack rather than the frontend alone.
Deep frontend expertise: strong command of TypeScript and modern frameworks (Angular and/or React), and experience defining frontend architecture at scale (modular package ecosystems or module federation, shared component libraries, build and delivery systems).
Experience building configurable or extensible platforms that serve multiple customer segments, verticals, or regions on a common foundation.
A track record of improving reliability and performance of production systems at scale, including observability, load-time and error-rate reduction, and resilience.
Demonstrated, daily use of AI-assisted engineering tools across the development lifecycle, with the judgment to validate output against quality, security, and performance standards.
Strong, structured communication and the ability to influence engineering and product leaders across team and pillar boundaries.
A customer-obsessed mindset, with the ability to walk in the user's shoes across diverse markets and balance competing business and engineering priorities.
A high standard of excellence and a genuine curiosity for raising the capabilities of the engineers around you.

Responsibilities

Define the client architecture strategy for RTO: how we build, compose, and ship client experiences so Axon can deliver unique workflows and experiences at scale across a broad set of market verticals and international regions.
Shape how the platform supports configurability and extensibility, so vertical- and region-specific experiences can be built on a shared foundation rather than forked or rebuilt for each market.
Set and evolve the frontend architecture that underpins this strategy, including module boundaries, shared component and platform libraries, build and delivery systems, and the patterns that let many feature teams own and ship their code safely and independently.
Steward cross-cutting platform concerns that span every client experience: auth and session management, logging, metrics, localization and internationalization, accessibility, and UI cohesion across products and regions.
Drive client reliability, performance, and quality at scale, owning the bar for load times, error rates, observability, and resilience for mission-critical real-time experiences serving a rapidly growing global user base.
Lead the use of AI-assisted engineering across the client development lifecycle, establishing reusable workflows, review protocols, and quality gates that make AI adoption practical and safe across teams.
Review key designs and architecture from engineers across RTO and partner teams, enforcing a high bar on availability, performance, maintainability, and usability.
Mentor and grow senior engineers, acting as a force multiplier who develops the next set of technical leaders for the organization.
Partner closely with product, design, and engineering leaders to translate roadmap goals across verticals and regions into sound technical strategy and durable architecture.
