Senior Platform Engineer (UI/UX and Integrations)

About Refractal

Refractal is an AI security company building the infrastructure organisations need to defend against autonomous AI threats. 2026 has shown that generally capable intelligence is here. The challenge now is modernising security to stop AI-enabled threats, whether they come from internal agents going rogue or from attackers using AI to become more dangerous.

Refractal was founded on cybersecurity and AI expertise from MIT, Microsoft, NASA and the U.S. Navy. Our product lets organisations detect AI-enabled threats at low cost without sacrificing detection quality. We take a practical approach to AI risk, combining proven cybersecurity methods with frontier AI security research.

Today, we work with governments and organisations that can't afford to get security wrong. We're backed by leading deep-tech and cybersecurity investors and are growing the team to deliver on this mission.

The role

You'll own the parts of the Refractal platform that customers see and connect to: the operator console, and the integrations that link Refractal to customers' AI tools and security stack. You'll work closely with our product designer and set front-end and integration standards in Podgorica with our London team.

What you'll do

• Build the operator console in React and TypeScript, turning designs into fast, accessible interfaces for security and compliance teams.

• Work with our product designer on workflows for policy authoring, triage, investigations and audit reporting.

• Build and maintain integrations with customers' AI platforms and security tools, including SIEMs, identity providers and observability platforms.

• Design the APIs and SDKs that customers use to connect their agents and tools to Refractal.

• Make integrations reliable through testing, monitoring and clear setup documentation.

Success in your first six months

• Console workflows you built are in customers' hands and measurably easier to use.

• Priority integrations are live, documented and supported.

• The front-end and integration standards you set are in use across the Podgorica team.

About you: essential

• 6+ years in software engineering, with deep front-end experience in React and TypeScript.

• A strong eye for UI and UX, and experience turning designs into polished, data-heavy interfaces.

• Experience building integrations with third-party APIs, including authentication, rate limits and error handling.

• Working knowledge of a backend language, ideally Python.

• Clear communication with designers, engineers and customers.

Nice to have

• Experience with SIEM, identity or observability platforms such as Splunk, Okta or OpenTelemetry.

• Experience building security or compliance products.

• Montenegrin, Serbian, Bosnian or Croatian.

Our values

Radical transparency. We believe the best work happens when everyone feels able to give and receive honest, constructive feedback.

Public service. We see AI security as a form of public service. Getting the AI transition right means putting the right infrastructure in place to manage the threats that come with it, and our work helps protect the institutions and services society depends on.

Fail fast. We test ideas early, seek feedback and learn quickly. We experiment rapidly and change course when something isn't working, without compromising on security.

Pragmatism, not dogmatism. We choose approaches based on how well they solve the problem. That means combining established cybersecurity methods with frontier AI research, questioning our assumptions, and changing our minds when the evidence changes.
