Why this role exists We’re looking for a full-stack

Lead Software Engineer

with

deep frontend expertise

who strengthens how user-facing software is designed, built, and evolved, while

helping other engineers grow their frontend capability through active coaching .

This role exists because strong frontend engineering requires

seniority, judgment, and experience . Many of our teams are backend-heavy, and this position provides hands‑on expertise to improve frontend quality, reduce risk, and raise confidence in frontend decision‑making across the department.

You will be a senior individual contributor within a Scrum team,

leading primarily in your specialist area rather than through formal team leadership . Your impact comes from high-quality execution, clear technical reasoning, and active coaching of other engineers.

Act as a

frontend subject‑matter expert

within your Scrum team and across the department.

Take ownership of complex, frontend‑heavy features and improvements.

Influence technical decisions through clarity, experience, and well‑reasoned trade‑offs.

Build high-quality full‑stack software

Design and develop full‑stack solutions with a strong emphasis on frontend architecture, usability, performance, and maintainability.

Work extensively with

AngularJS, React, and TypeScript , while collaborating effectively across backend and integration layers.

Improve existing frontend codebases pragmatically, steadily reducing complexity and technical risk.

Mentor and upskill other engineers

Dedicate part of your time to

actively mentoring and coaching engineers

across the department.

Support backend‑focused engineers in strengthening their frontend skills through:

Pair programming

Design and code reviews

Hands‑on guidance in real production codebases

Propose concrete improvements and trade‑offs at feature level to avoid late surprises.

Collaborate effectively within and across teams

Work closely with engineers, Product Owners, and QA to deliver coherent, user‑centred solutions.

Support shared ownership of code without becoming a bottleneck or gatekeeper.

Contribute constructively to technical discussions while operating within agreed architectural boundaries.

Operate in a modern cloud environment

Develop and maintain software running on

Azure ,

Kubernetes , and

Windows‑based platforms .

Work comfortably with

REST and SOAP APIs , distributed systems, and

SQL Server .
