Location: London Office/Hybrid (1–2 days on site) Schedule: Full-Time The Role Most security roles protect data. This one protects evidence. Asset Reality builds mission-critical infrastructure for clients in law enforcement and government, operating in environments where records are examined adversarially and the stakes are high. You will join a small engineering team as a working engineer with deep security expertise. This is not an advisory role and it is not a governance role. You will ship production code alongside the rest of the team — Go services, Postgres, React, all on AWS — and you will be the person who makes sure that what we ship stands up to adversarial scrutiny. Security here is not a separate function reviewing the team's work from the outside. It is a discipline embedded in how the team designs, builds, and operates the product. You will set the standard for that.
