Who we are?
We are a software Consultancy, who provide highly skilled consultants to support client business needs. We work within private and public sectors, including financial services, government, healthcare, property, education, oil & gas, broadcasting, gaming and renewable energy organisations. We are continuously growing as a business, with new client wins and have multiple offices located in the UK, Poland and in Canada.
About the Role

As our Engineering Practice continues to grow, we are looking for a Principal Frontend Consultant to help shape its future. This is a senior leadership role that sits at the intersection of technical strategy, people development, and client impact.

You will work closely with our Head of Engineering to define and uphold frontend engineering standards, lead our Communities of Practice, develop the engineers around you, and act as a trusted technical partner to our clients. At the same time, you will remain hands‑on - taking on Tech Lead responsibilities within client engagements when needed and leading by example in craft.

This is not a purely managerial role, nor a purely technical one. It requires fluency across both and the credibility to operate at the Principal level in all three pillars of our framework: client work, internal collaboration, and technical specialism.

What You’ll Be Doing

Technical Strategy & Standards

Define and own frontend engineering standards across the practice — architecture patterns, testing philosophy, accessibility compliance, and performance benchmarks

Contribute to the broader engineering strategy alongside Heads of Practice and other Principals

Establish what good looks like across Core Web Vitals, WCAG compliance, and developer experience — and embed those standards into delivery processes across all engagements

Stay credibly hands‑on: lead by example in complex architectural challenges, performance problems, and high‑stakes delivery moments

People Leadership & Development

Line manage engineers up to Senior level — supporting their growth, contributing to performance reviews, and providing clear, evidence‑based guidance

Mentor engineers across the practice, not just your direct reports — actively developing the next generation of Senior and Principal‑level talent

Define and maintain the hiring bar for frontend engineering; lead and shape our interview process

Foster a culture of collaboration, continuous learning, and high standards

Community of Practice Leadership

Lead the Frontend Engineering Community of Practice — set the agenda, drive output, and ensure it creates real value for the engineers involved

Champion best practices in frontend development across the practice: component architecture, testing, accessibility, performance, and developer tooling

Collaborate with Principal Consultants across Delivery, UCD, QA, and DevOps to align strategy and drive cross‑functional improvements

Drive internal initiatives that produce lasting, measurable improvements to how we work

Client Engagement & Delivery

Act as a trusted technical advisor to senior client stakeholders — translating business challenges into scalable frontend engineering approaches

Lead or materially contribute to technical proposals, architecture sessions, and pre‑sales conversations

Take on Tech Lead or Senior Developer responsibilities within client engagements, setting technical direction and ensuring engineering excellence throughout the delivery lifecycle

Handle complex and challenging client situations with confidence and composure — including escalations and high‑pressure delivery moments

Contribute to the retention and growth of client accounts through the quality of your technical leadership and relationships

What We’re Looking For

Experience & Background

8+ years of experience in frontend software engineering, with meaningful time at Senior Consultant level or equivalent

A track record of technical leadership on complex, client‑fac­ing engagements — not just strong individual contribution

Demonstrable experience mentoring or managing engineers and helping them grow

Prior experience in a consultancy or agency environment is strongly preferred

Technical

Deep expertise in modern frontend development — component architecture, state management, build tooling, and the wider ecosystem

Strong, practical knowledge of accessibility (WCAG 2.1 AA as a baseline), web performance (Core Web Vitals), and testing across unit, integration, and E2E

Able to make high‑quality architectural decisions in complex, ambiguous environments and articulate the trade‑offs clearly

Comfortable contributing hands‑on in critical delivery situations — this is not a purely strategic role

Proven ability to lead Communities of Practice and shape engineering culture, not just participate in it

Strong stakeholder management and communication skills — equally comfortable talking to engineers and to senior client decision‑makers

Collaborative by nature — works closely across disciplines (Delivery, UCD, QA, DevOps) and brings people with them
