Principal Engineer, Technical Assessment

About the role

Proxify is Europe's largest network of vetted software developers and needs a Principal Engineer, Technical Assessment to design how it evaluates applicants. The role is a senior, individual-contributor position reporting to the VP of Assessment, owning the direction end-to-end: what is evaluated, how and how it scales. It is remote in Europe, with visits to the Stockholm HQ a couple of times per year, and requires English at C1 level or higher.

Key responsibilities

• Own technical vetting across engineering roles and seniority levels, turning strong on-the-job performance into clear, measurable signals.
• Design evaluations: build interviews, tests, work simulations and scoring guides, including formats that do not exist yet.
• Rethink evaluations for the AI era, deciding what matters when engineers work with AI agents daily.
• Use AI in the work itself: build and maintain technical content, improve consistency between interviewers and support better decisions at volume.
• Prove what works by connecting evaluation results with engagement performance, filtering signal from noise, A/B testing and scaling what works.
• Set the standards and quality controls for fair evaluations across thousands of applicants a month.

Required profile

• A strong hands-on software development background and deep expertise in at least one technical area.
• Strong analytical, data-driven skills, with an understanding of reliability, consistency, bias and predictive value.
• Hands-on use of AI-assisted development tools and a practical view of where technical evaluation should go.
• Communication skills to set direction and influence people without formal authority.
