About the role

Key responsibilities & impact

Set the technical direction and design quality within your team, making the local trade-offs between scope, speed, and quality.
Ensure your team's systems are highly reliable, observable, and operationally ready.
Own the software development lifecycle, keeping the team inside our engineering guardrails or explicitly logging exceptions.
Partner with your Engineering Lead and the Director of Technical Strategy to keep your team's technical decisions aligned with Numan’s broader vision.
Lead a team that owns problems from initial shaping right through to measuring the live result.
Ensure every engineer can explain *why* their work matters to the customer and exactly which metric it aims to move.
Use feature flags, incremental rollouts, and rapid rollbacks to test signals before committing to heavy technical investments.
Partner with Product and Design to co-author OKRs, manage a short 2-4 week portfolio of bets, and decide the order of implementation.
Hire, line-manage, and mentor your engineers. You will own their performance, personal growth, and career development.
Own the health, efficiency, and psychological safety of the team, ensuring an honest environment where people thrive.
