COMPANY:CultureTestSteven.com
REPORTING TO: CTO, CultureTest
LOCATION: London
This role sits within CultureTest, a venture within theSteven.com ecosystem - one of the companies we are building and backing as we scale the infrastructure behind high-performing teams.
Most hiring decisions rely on CVs, interviews and gut feel - all weak signals that rarely predict how someone will actually behave inside a company. As teams scale and founders step back from hiring, the decisions that matter most often get made with the least structure.
CultureTest introduces company-specific, scenario-based behavioural screening early in the hiring process. Instead of generic personality tests, we help teams evaluate candidates against how their company actually works, before interviews shape perception.
Culture Test are early-stage, working directly with customers, shipping quickly and iterating based on real usage.
Own the front-end experience end to end - designing and shipping the interfaces hiring teams and candidates interact with every day - and help define how CultureTest builds product as the platform scales.
As the first dedicated frontend engineer, you'll take ownership of the existing frontend, build in Next.js and TypeScript, and have the opportunity to contribute across the whole stack over time. You'll work closely with the CTO to shape frontend architecture, product decisions and engineering standards, with a high level of autonomy and real influence over both the product and the engineering culture.
