Our client is looking for a Tech Lead for the TSS Journeys cluster within the Product Journey Tribe. This is not a people‑management role. The Tech Lead is the technical conscience of the team and the right hand to the Solution Architect, ensuring that architectural decisions translate into concrete guidance, implementation standards and consistent delivery across internal teams and external vendor teams.
The ideal candidate combines strong stakeholder management, persuasive communication, coaching, and the ability to steer vendors in a complex multi‑team technical environment.

Responsibilities:
Architecture & Technical Leadership

Translate architectural vision into practical implementation standards and guardrails.
Co‑own the domain architecture together with Solution Architects, Product Owners and Lead Analysts.
Ensure correct implementation of architectural decisions in the codebase.

Quality & Engineering Excellence

Enforce standards for security, maintainability, testability, scalability and observability.
Perform architecture‑level code reviews and ensure high‑quality engineering outcomes.

Vendor Steering & Multi‑Team Alignment

Challenge and guide vendor teams to ensure alignment with the company's technical standards.
Operate effectively within a multi‑vendor, multi‑team landscape.

Cloud & Platform Enablement

Support teams in cloud adoption (AWS, GCP) and container platforms (OpenShift/Kubernetes).
Provide practical guidance bridging theory and hands‑on engineering.

Modernisation & Innovation

Reduce technical debt and drive modernization initiatives.
Introduce and promote cloud‑native and AI‑driven solutions.
Organize coaching, training and knowledge‑sharing sessions.

Stakeholder & Business Communication

Communicate effectively with Product Owners, Business Analysts, architects and senior stakeholders.
Balance priorities between the companies, navigating a complex and sometimes political environment.

Delivery & Release Optimisation

Improve delivery pipelines, release management, and patching processes.
Support teams through ongoing large‑scale transformations.

This Role Is NOT :

Not a team lead or scrum master — you don't manage people, sprints, or backlogs
Not a solution architect — you work alongside the SA as their technical sparring partner, not in place of them
Not a business analyst — you challenge BAs and consulting FAs on technical feasibility; you don't own functional analysis
Not a project manager — your authority comes from technical expertise and the quality of your guidance, not from a reporting line
