About the role

Who are OnCommerce? OnCommerce is a global selling platform that powers a growing network of retail channels, including: OnBuy - The only marketplace in the world to give customers instant Cashback on everything easyShop - An all-new marketplace created in collaboration with the easy® family of brands Comet - The iconic UK tech brand making its return later this year OnCommerce is growing fast, launching new brands and scaling to power the future of ecommerce. Be Part of the Story OnCommerce is constantly evolving. Everyone here plays a hands-on role in shaping what comes next, building brands that make an impact across global markets. There's no red tape or rigid corporate structure; just smart people taking ownership and figuring things out as we build something big together. The pace is fast, priorities shift, things aren't always perfectly set up, and you'll often need to get stuck in and solve problems. But if you thrive in that kind of environment, you'll have real influence, real ownership, and the chance to grow with a rapidly scaling business. Why This Role Exists OnCommerce is transforming its platform and operating model while continuing to trade live, every day, across Buyer and Seller domains. That dual demand, build the future, protect the present, doesn't run itself. This role exists to hold both at once: the standard the engineering team is held to, the resilience of what's live today, and the continuity of delivery and culture as the organisation restructures around it. Role Overview: This is a senior leadership role accountable for the day-to-day performance and long-term evolution of OnCommerce's engineering function, spanning both the current platform and its transformation to a modern, composable architecture. The Engineering & Operations Lead owns engineering delivery, operational resilience, and standards across all squads, ensuring strong processes translate into reliable services, predictable delivery, and high-performing teams. Working alongside the Transformation and Solution Architecture Leads, you will balance live operations with platform evolution, ensuring neither stability nor progress is compromised. Success in this role requires leading people, setting clear expectations, and driving accountability for outcomes, while making effective trade-offs between short-term delivery and long-term sustainability. Key Responsibilities Product Engineering Ownership & Accountability Define and enforce clear ownership boundaries across the engineering team, by domain (Buyer / Seller / Platform), holding every contributor accountable regardless of sourcing model (permanent or partner-led) Track and report Throughput and Instability per domain, so standards are visible and enforceable, not aspirational Transformation Continuity Hold delivery consistent through every point of disruption the transformation introduces: nearshore/offshore onboarding, domain moves, headcount change Partner with the Transformation Lead to ensure structural change doesn't degrade live delivery Standards & Engineering Governance Own the engineering standard across both the current platform and the target state Review the Transformation Lead's roadmap for engineering-standard and operational impact before commitments are made Own how modern and legacy architecture coexist during migration, guarding against legacy practices and assumptions leaking into the new platform People Leadership & Team Engagement Lead and develop engineering capability across squads (including DevOps and platform functions) Coach and support Tech Leads to build consistent leadership standards across teams Foster a culture of ownership, accountability, and continuous improvement Identify capability gaps and support hiring, development, and succession planning Own resource planning, including capacity, skills mix, and on-call structure Operational Resilience & Incident Ownership Establish and run a two-tier resolver model: Ops on-call for standard support and runbook-driven issues, Product Engineering (Buyer/Seller) as the resolver group for genuine engineering problems Build rota depth (minimum 3 engineers per domain, or full team where smaller) so resolution doesn't depend on any one individual Drive a genuinely blameless Post-Incident Review culture, building on the existing Incident Management SOP Security & Risk Embed secure coding practice, SAST/DAST scanning, and OWASP-aligned standards into the engineering definition of done Surface security risk in business terms (exposure, cost to fix vs cost to carry) and route it to the appropriate decision-maker, rather than carrying risk-acceptance decisions unilaterally Technical Debt Management Identify, log, and manage technical debt within day to day delivery Escalate strategic trade-offs (rebuild vs patch, roadmap sequencing) to the Solution Architecture Lead, owning visibility and routine remediation rather than the strategic call Delivery & Execution Work with Product Owners (Buyer and Sel
