Software Engineer II

AI overview

Contribute to the development and modernization of a secure digital evidence platform used by law enforcement and defense, focusing on reliability and cross-technology collaboration.

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 Software Engineer II on the Evidence Local team, you’ll help build and evolve Axon’s on-premises and hybrid digital evidence platform, used by agencies that require full control over highly sensitive data.
Evidence Local underpins how video, audio, and other digital evidence is securely ingested, processed, stored, and retrieved in regulated environments such as law enforcement, government, and defense. These are mission-critical systems where reliability, security, and correctness are essential.

This is a hands-on backend role focused on building and modernising distributed systems and APIs. While parts of the platform are built in different backend languages, the team prioritises strong backend engineering fundamentals over expertise in any single stack. Engineers regularly work across multiple technologies, collaborating closely to modernise existing services, design new capabilities, and continuously improve system resilience, performance, and reliability.

Work Location

This role is based out of our London office and follows a hybrid model. We value in-person collaboration and ask team members to work onsite Tuesday through Friday, with flexibility to work remotely on Mondays (unless an approved accommodation applies). Our in-office culture is designed to support collaboration, mentorship, and shared ownership.

What You’ll Do

  • Design, build, and maintain backend services and APIs that support Evidence Local’s on-prem and hybrid deployments.
  • Contribute to both new development and the modernisation of existing systems, improving scalability, reliability, and maintainability.
  • Participate in architecture discussions around availability, security, data integrity, and performance.
  • Work on systems that handle high-throughput data ingestion and long-lived workloads.
  • Write clean, well-tested production code and participate in code reviews and design sessions.
  • Leverage AI-accelerated development tools thoughtfully as part of your daily workflow using them to speed up iteration, explore solutions, and improve quality, while applying strong engineering judgement to everything that ships
  • Collaborate with product managers, QA, and platform teams to deliver reliable, observable features.
  • Own features end-to-end — from design and implementation through deployment and production support.
  • Participate in incident response, retrospectives, and continuous improvement of engineering practices.
  • Bring a thoughtful, quality-first mindset to systems people depend on in real-world, high-stakes environments.

What You Bring

  • 3+ years of professional software engineering experience, primarily in backend roles.
  • Strong experience with one or more backend languages (e.g. C#, Java, Go, Python, etc.).
  • Solid understanding of distributed systems, RESTful APIs, and service-oriented architectures.
  • Experience working with SQL and/or NoSQL data stores.
  • Familiarity with cloud, hybrid, or on-prem environments (Azure experience is a plus).
  • Ability to reason about performance, reliability, fault tolerance, and security.
  • Experience with testing, CI/CD pipelines, and supporting production systems.
  • A collaborative mindset and comfort working in cross-functional teams.

Nice to Have

  • Across multiple backend languages (such as C#, Java, or Python)
  • Background modernising legacy systems or working in long-lived platforms.
  • Exposure to on-prem or hybrid deployments and security-sensitive environments.
  • Familiarity with messaging systems, background processing, or event-driven architectures.
  • Experience with observability tooling (logging, metrics, alerting).
  • Interest in AI-assisted development tools and workflows.
  • Passion for building trustworthy, mission-critical systems.

Benefits That Benefit You

  • Competitive base salary and RSUs
  • Pension plan with matching contributions
  • Private health insurance and cash plans
  • 30 days paid holiday plus UK public holidays
  • Enhanced maternity and paternity leave
  • GymPass subscription
  • Life assurance and income protection
  • Career growth, learning support, and wellness resources
