Job Specifications

Oliver Wyman is a global leader in management consulting. With offices in more than 70 cities across 30 countries, Oliver Wyman combines deep industry knowledge with specialized expertise in strategy, operations, risk management, and organization transformation. The firm has more than 7,000 professionals around the world who work with clients to optimize their business, improve their operations and risk profile, and accelerate their organizational performance to seize the most attractive opportunities.

Oliver Wyman is seeking a Principal Software Engineer (Cloud) to join our Retail Solutions team in the UK, with London or Newcastle being our preferred office locations but we can offer some flexibility.

Retail Solutions is a new kind of team within Oliver Wyman: an internal product startup that blends a strong engineering culture and an obsession for creating products that deliver the world’s biggest retail impact.

Our suite of retail tools empowers merchandising teams to address complex analytical challenges and make the most important commercial decisions at the heart of every retailer: optimizing assortments, promotional programs, and pricing strategies.

About the role:

The Retail Solutions engineering teams build and operate our SaaS products, enabled by our cloud Platform. The combination of our Platform together with common services, patterns and approaches, unlocks our ability to innovate and build new products and functionality, ultimately increasing our value proposition.

We are looking for an experienced Engineer to join our Application-Enablement team, serving as the bridge between our SaaS product engineering and our Platform teams. This team leads some of our most innovative and cutting-edge work such as the extraction of new common services and/or the creation of new products. This is a hands-on role that requires a strong SW engineering and cloud engineering foundation.

The role will also require solid collaboration and leadership skills. You will collaborate with our product teams as well as our Platform team, facilitating the work on initiatives that involve multiple of these teams. And since the Application-Enablement team will often spearhead the adoption of new patterns, strategies and platform functionality, you will also have the leadership and organizational skills to see these adopted across our Engineering teams.

You will be comfortable working with Retail’s leadership to develop and understand the organizational goals and priorities. You will feed these into the roadmap of the application-enablement team, balancing short-term impact and long-term vision.

Key Responsibilities

As a Principal Engineer in our application-enablement team, you will:

Lead the design, development, and operation of new services and functionality added to our SaaS offering.
Facilitate knowledge sharing and cross-team collaboration across the Engineering organization, maximizing the impact of the application-enablement team initiatives.
Drive the roadmap of the application-enablement team, in collaboration with Retail leadership and engineering teams, balancing short-term impact with long-term vision.
Champion best practices in cloud architectures such as 12-factor apps, observability, and others, to meet high availability, performance, security, and cost efficiency needs of our products and platform
Lead the adoption of solutions, patterns and strategies that improve efficiency and development experience across our Engineering organization.
Evaluate and integrate existing or emerging cloud services and open-source technologies to enhance our products and platform capabilities and maintain a competitive edge.
Collaborate with security and compliance teams to embed policies and controls into our products and platform, ensuring adherence to organizational and regulatory standards.
Foster a culture of continuous improvement, mentoring and leading engineering teams to deliver high-quality solutions and operational excellence.

Who we are looking for…

You’ll have a solid understanding of software, cloud and platform engineering fundamentals, an ability to deliver new solutions into production and a strong desire to learn, are key to succeeding in the role, rather than perfectly matching our stack.

That said, these are the most important technical skills for the role:

7+ years of engineering experience overall, with at least 2-3 years in a similar Principal SW Engineering or SW Architect roles.
Our codebase uses primarily JavaScript and Python, across various web applications, backend services and analytical processes, and leverages frameworks such as Express.js, Vue, Flask or Pandas.
This is a hands-on role; you should be comfortable writing code and building solutions.
Experience designing and building distributed applications and architectures.
You will be comfortable with different architectural styles and with concepts such as DDD, service-mesh or data-mesh.
Experience building, deploying and oper
