Principal Software (Data) Engineer - £105,000 + exceptional benefits - Architect the Future of Consumer Tech - Remote or hybrid in Central Bath

My client is hiring a Principal Software Engineer – Data, to help shape the future of a high-impact, consumer-facing platform used by millions each month. This is a rare opportunity to join a well-established but fast-evolving tech organisation that’s doubling down on modern architecture, engineering autonomy, and data-driven product development.

In this role, you’ll take ownership of the data platform’s evolution, influence architectural decisions, and collaborate closely with engineering, product, and commercial teams to deliver reliable, scalable systems that make a real difference to users’ lives.

Why this role is exciting

• Real ownership over platform and architectural decisions
• Deep collaboration with product, design, and commercial stakeholders
• A mission-led team that cares about technical quality and customer outcomes
• Strong focus on delivery health, data observability, and engineering best practice
• A role designed for someone who enjoys building, influencing, and mentoring

What you’ll do

• Design and evolve modern data architecture (data mesh, lakes, dimensional modelling)
• Build robust, event-driven pipelines with Python, SQL, and cloud-native tooling
• Improve the delivery and reliability of data products and observability tooling
• Lead by example: mentor engineers, contribute to technical standards, and drive team alignment
• Work closely with stakeholders to translate business needs into scalable solutions

Tech environment includes

(If you haven’t worked with every tool, that’s totally fine — my client values depth of thinking and engineering craft over buzzword familiarity.)

What they’re looking for

• A strong background in building and scaling data platforms in cloud-native environments
• Experience designing data models, pipelines, and architectural patterns at scale
• A track record of technical leadership, mentoring, and influencing beyond your own team
• Familiarity with delivery metrics (DORA ideally, but not a must have), observability, and modern DevOps principles
• TDD
• A collaborative mindset, a bias for action, and a desire to work on meaningful products

Benefits include

• 33 days holiday
• 12 weeks maternity/paternity leave
