Principal Engineer - Merchant Experience Platform
This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Principal Engineer based in United Kingdom.
As a Principal Engineer stepping into an Architect-level role, you will shape the future architecture of a large-scale Merchant Experience platform.
You will own the technical direction of the pillar and influence engineering strategy across multiple teams.
The role combines deep hands-on technical expertise with architectural leadership, mentoring, and cross-team collaboration.
You will tackle complex challenges involving scalability, performance, distributed systems, integrations, and domain modeling.
You will work closely with fellow architects and engineering leaders to establish consistent standards, practices, and technical guardrails.
You will also champion Domain-Driven Design and help teams turn architectural vision into robust, scalable solutions.
This is an opportunity to have broad technical influence in a global, collaborative, and cloud-native engineering environment.
Accountabilities
- Own and share accountability for the technical direction, architecture, and solution design within the Merchant Experience pillar.
- Make and guide key architectural decisions, reviewing technical and design documentation to ensure alignment with broader platform strategy and engineering standards.
- Contribute to organization-wide engineering strategy and standards through participation in architecture-focused initiatives and councils.
- Support engineering teams during implementation by creating proofs of concept, clarifying architectural decisions, and resolving complex design challenges.
- Investigate and address architecture-related challenges across performance, scalability, integrations, distributed systems, and other critical areas.
- Mentor engineers and technical leaders on architecture, design techniques, coding standards, and engineering best practices, extending technical influence across multiple teams.
- Collaborate with architects and engineering teams to establish cohesive architecture practices, guardrails, and standards, and drive their adoption.
- Act as a subject-matter authority for Domain-Driven Design and architectural best practices, educating and mentoring teams to promote consistent, high-quality solutions.
