Job description

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

This role is primarily for the DEMS Ingestion team which is responsible for the upload of evidence files both from 3rd party clients as well as Axon devices such as Body Worn Cameras. We deal with large throughput upload requests (~Terabytes) and have an increasing need for a strong grasp of multi-cloud architecture (AWS & Azure).

The team largely is a backend focused team leveraging mainly GoLang and Scala. Cloud technologies include blob storage, CDNs, stateful APIs, multi-part file upload, end-to-end encryption, SQL, event driven infrastructure, and caching. We are also making increasing use of AI to accelerate our development process through improved quality guardrails.

An ideal candidate would be a strong backend engineer with a mind for system design across multi-cloud infrastructure. They should be a strong communicator of complex technical details and able to consider a wide range of use‑case scenarios and risks in their designs.

They should also possess well developed leadership soft skills as this role is expected to lead other engineers and act as a force multiplier for the team as whole. They should have a strong technical foundation that others on the team can rely on and be approachable and willing to help their team grow.

What You’ll Do

Location

This role is based out of our Seattle Office and follows a hybrid schedule.

We rely on in‑person collaboration and ask that team members work onsite Tuesdays through Fridays, with the flexibility to work remotely on Mondays, unless there is an approved workplace accommodation.

We believe that connection fuels innovation, and our in‑office culture is designed to foster meaningful teamwork, mentorship, and shared success.
