Security Engineer

Relay is a digital banking platform that gives self-made business owners the tools and know-how to be great with money—bringing clarity, confidence, and control to every dollar earned, so they can turn hard work into lasting success. We do this by replacing financial guesswork with real visibility, transforming cash flow from a constant source of stress into a clear signal owners can use to run stronger, more resilient businesses.

Our mission is to increase the success rate of small businesses. Traditional banking has been a growth limiter rather than a growth enabler. We're changing that. Relay is the all-in-one, collaborative money management platform. We're building for employer SMBs and their finance function, and delivering a human-centric customer experience.

Relay is entering an exciting new chapter of growth, and we're looking for a Security Engineer to join the purple team in our security organization. This is a rare early-career opportunity to work across both offensive and defensive security with the mentorship and support to grow quickly.

As a Security Engineer on Relay's purple team, you'll help design and run exercises that test our defenses, surface vulnerabilities, and drive real improvements. You'll work closely with senior security engineers who will coach you through the harder problems, and you'll take increasing ownership of your own workstreams as you build depth.

What You’ll Be Doing

• Help plan and run security simulations, and contribute to the security awareness program that comes out of them

• Review how sensitive customer and financial data is accessed in Relay's admin dashboards, and help implement improvements

• Contribute to strengthening security for our developer environments, including tooling, packages, and access to production

• Work alongside delivery, IT, and business teams to turn test findings into tangible fixes, and follow them through to done

• Develop and manage Cyber Awareness exercises, including internal phishing attacks

• Research emerging threats (e.g. AI misuse, supply chain risks, identity and access challenges, Shadow IT) and help the team figure out what they mean in Relay's context

• Share what you find in a way that educates and drives action, building your voice in Relay's security culture

Who You Are

• You have roughly 2–4 years of experience in security, or in an adjacent technical role (IT, infrastructure, software engineering, SOC) with meaningful security exposure
