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

Axon is on a mission to protect life. As part of that mission, Axon Assistant is changing how public safety professionals interact with technology - delivering real-time translation, policy guidance, and AI-driven support across voice, mobile, and web platforms. It's a product that demands reliability, speed, and clarity - in the moments when it matters most.

As a Senior Software Engineer I, you'll play a central role in building the backend systems that bring Axon Assistant to life. You'll work across real-time APIs, LLM-integrated services, and edge-to-cloud pipelines to help first responders get intelligent, actionable support exactly when they need it. You'll contribute to architectural decisions, mentor other engineers, and help us scale a product that will operate globally and in high-stakes environments.

You're someone who loves writing clean, scalable services - but who also thrives in ambiguity and is motivated by solving problems that don't yet have clear answers. You care about system design, performance, and shipping features that support real people doing critical work. And you bring enough experience to know when to challenge, when to align, and how to build software that lasts.

What You'll Do

• Design and build scalable, fault-tolerant backend services that support real-time AI experiences across Axon devices, mobile apps, and web interfaces.
• Collaborate with Applied AI teams to integrate large language models and related services into production systems - with a focus on latency, reliability, and observability.
• Contribute to and lead architecture discussions, including model orchestration, caching strategies, data storage patterns, and compute optimization.
• Write production code (Node.js, Python, or similar), review pull requests, and promote engineering best practices across the team.
• Collaborate cross-functionally with product, design, and client teams to deliver intelligent, usable features on a fast-moving roadmap.
• Improve how we operate: help shape sprint rituals, incident response, system monitoring, and long-term platform health.
• Mentor and support other engineers, helping grow a strong engineering culture built on trust, ownership, and execution.

What You Bring
Required Skills

• Bachelor's degree in Computer Science, Engineering, or a related field.
• 6+ years of professional software development experience, ideally in backend or platform teams.
• Strong proficiency in backend service development in Node.js, Python, Go, or similar languages.
• Experience designing and operating cloud-native systems (AWS, Azure, or GCP) with a focus on scalability and resilience.
• Familiarity with AI/ML systems, or demonstrable ability to quickly ramp up in highly technical, ambiguous domains.
• Strong knowledge of REST APIs, distributed system design, and performance optimization.
• Experience with both SQL and NoSQL data stores, caching layers, and observability tooling (e.g., Prometheus, Datadog).

Nice to have:

• Experience deploying or integrating LLMs or NLP models in production systems.
• Comfortable balancing short-term execution with long-term architectural thinking.
• Passion for building highly-available systems that power mission-critical experiences.
• Interest in or exposure to real-time systems, edge computing, or high-trust user domains (e.g. healthcare, defense, finance).

Benefits that benefit you

• Competitive base salary and RSUs
• Comprehensive pension plan with matching contribution
• Private health insurance & cash plans
• 30 days paid holiday + UK public holidays
• Enhanced maternity/paternity leave
• GymPass subscription
• Life assurance & income protection
• Career growth support and wellness resources
