Oliver Wyman
Build products that shape decisions at the world's largest retailers
At Oliver Wyman, we're known globally for helping organisations solve their toughest strategic challenges. Within Oliver Wyman, Retail Solutions is something different: a product-focused engineering organisation building SaaS solutions that help retailers optimise assortments, pricing, promotions and other critical commercial decisions.
We combine the pace and ownership of a startup with the reach, expertise and client impact of a global consulting firm.
We're looking for a Senior Lead Software Engineer (Full Stack) to join one of our product teams and play a key role in shaping the future of our platform and products.
This is a hands-on technical leadership role for someone who enjoys solving complex engineering challenges, building scalable cloud-native systems, and helping teams deliver exceptional software.
As a Senior Lead Engineer, you'll help drive both technical direction and delivery, with your main responsibilities being:
Lead the design, development and operation of new capabilities across our SaaS products.
Make architectural decisions that balance immediate business needs with long-term scalability and maintainability.
Work closely with product, engineering and business leadership to shape product roadmaps and technical strategy.
Identify and drive improvements across performance, reliability, scalability, security and developer experience.
Champion modern engineering practices, including AI-assisted development tools such as GitHub Copilot.
Lead the adoption of new patterns, frameworks and platform capabilities across teams.
Mentor engineers and foster a culture of continuous learning, operational excellence and high-quality delivery.
Partner with platform, security and compliance teams to ensure our products meet organisational and regulatory standards.
Contribute directly to production code and remain deeply involved in technical implementation.
We're more interested in strong engineering fundamentals, leadership and problem-solving capability than a perfect match to every technology in our stack, but you will have:
7+ years of software engineering experience
Experience as a Senior Engineer, Lead Engineer, Staff Engineer or Software Architect
A degree in Computer Science, Engineering, Data Science or a related field (preferred but not essential)
Certifications such as Azure Solutions Architect or CKA (beneficial but not required)
Experience working in consulting or client-facing environments (helpful but not essential)
You'll likely have experience with:
Building and operating modern full-stack applications using technologies such as JavaScript/TypeScript and Python
Frameworks such as Express.js, Vue.js, Flask and Pandas
Designing distributed systems, service-oriented architectures and microservices
Cloud-native development, ideally on Azure
Kubernetes-based platforms and deployment practices
AKS and supporting technologies such as ArgoCD, Helm, Dapr and GitOps workflows
Database technologies including MongoDB and PostgreSQL
DevSecOps, Infrastructure as Code and CI/CD practices
Large-scale data platforms, data warehouses or lakehouses (Databricks experience is advantageous)
Why Join Oliver Wyman Retail Solutions?
Our products support some of the world's largest retailers in making critical commercial decisions. You'll see the direct impact of the software you build.
We value strong technical thinking, continuous improvement and collaborative problem-solving. Great ideas can come from anywhere.
You'll be trusted to make decisions, shape solutions and influence the future direction of our products and platform.
You'll work within a fast-growing product organisation backed by the scale, reputation and expertise of Oliver Wyman.
Our engineers are distributed across multiple countries, with strong hubs in the UK and Spain, creating a collaborative and inclusive environment built on learning and shared success.

If you're excited by the challenge of building cloud-native products at scale, influencing technical strategy, and working with a team that genuinely cares about engineering excellence, we'd love to hear from you.
