Job Description

Just imagine helping millions more shoppers discover the right product while a platform handles 150% more traffic at a fraction of the cost. Then make it real.

About the role

As our Lead Software Engineer, you'll help shape the future of the LEGO Group's digital shopper experience across LEGO.com, mobile apps, and the foundations that support them. This is a hands-on technical leadership role where you'll spend most of your time contributing directly or indirectly to delivery, guiding architecture, and helping teams make sound technical decisions. You'll bring a broad systems view while staying close to the code, working across product teams that serve shopper and retail experiences at significant scale.

Required Qualifications

• Built and operated production software in JavaScript and TypeScript at scale.

• Led architectural decisions for large public-facing digital products, documenting trade-offs and long-term outcomes.

• Delivered cloud-native services on AWS, Azure, or GCP, including distributed or microservice-based systems.

• Shaped technical direction across multiple teams while remaining an active contributor to software delivery.

• Implemented GraphQL-powered applications or services in production environments.

• Improved platform scalability, performance, or operational cost through measurable engineering changes.

Preferred Qualifications

• Developed and supported modern React, Next.js, React Native, or Expo applications.

• Designed and operated event-driven architectures in production.

• Managed CI/CD pipelines and infrastructure as code using tools such as GitHub Actions, Terraform, or CDK.

• Scaled consumer commerce platforms with significant traffic growth and availability requirements.

What you'll build

• Technical direction for product areas across LEGO digital shopper experiences.

• Architectural improvements that support continued traffic growth while maintaining efficiency and reliability.

• Solutions that improve product discoverability and support evolving European compliance requirements.

• Engineering standards covering testing, security, observability, accessibility, and performance.

• Strong technical partnerships with product managers and digital designers from discovery through delivery.

If you've worked in a role where you've scaled public-facing platforms, balanced technical and business outcomes, and lived with the long-term impact of your architectural decisions, you'll feel at home here. What matters most is bringing systems thinking, practical judgement, and a track record of turning complex challenges into sustainable solutions.

Life on the team

You’ll join Shopper Technology, a collaborative engineering environment focused on creating great digital experiences for shoppers. Lead Engineers act as visible technical leaders within their teams, helping others grow while contributing meaningful technical work themselves. We work in a hybrid rhythm, spending three days together in the office, and value people who can zoom into the detail when needed while keeping sight of the bigger picture.

What success looks like

Success means helping teams evolve the foundations behind LEGO shopper experiences through steady, incremental improvements that scale. You’ll work closely with product teams, engineers, designers, and retail-focused stakeholders as traffic continues to grow and new platform capabilities are introduced. You’ll be recognised for making good architectural calls, improving efficiency, and helping teams deliver outcomes that create value beyond their own products.

What’s in it for you?

Here is what you can expect:

• Family Care Leave - We offer enhanced paid leave options for those important times.
• Insurances – All colleagues are covered by our life and disability insurance which provides protection and peace of mind.
• Wellbeing - We want our people to feel well and thrive. We offer resources and benefits to nurture physical and mental wellbeing along with opportunities to build community and inspire creativity.
• Colleague Discount – We know you'll love to build, so from day 1 you will qualify for our generous colleague discount.
• Bonus - We do our best work to succeed together. When goals are reached and if eligible, you'll be rewarded through our bonus scheme.
• Workplace - When you join the team you’ll be assigned a primary workplace location i.e. one of our Offices, stores or factories. Our hybrid work policy means an average of 3 days per week in the office. The hiring team will discuss the policy and role eligibility with you during the recruitment process.

Children are our role models. Their curiosity, creativity and imagination inspire everything we do. We strive to create a diverse, dynamic and inclusive culture of play at the LEGO Group, where everyone feels safe, valued and they belong.
