Who are we?
We’re the original pioneers in connected commerce marketing. Since 2008, we’ve been partnering with major retailers, powering global brands, and building meaningful connections with shoppers.
About the role
We are looking for a Software Engineer to build and maintain features that make SMG's Plan-Apps platform work for our clients. Working inside an agile product squad, the role delivers well-scoped engineering work end to end, from implementation through to production, within the patterns and standards the team has established. This is a role for someone past the early stage of their career and ready to take real ownership of what they ship, but who still wants the structure of a squad with senior engineers around them to learn from. At SMG you will be working on a product used daily by some of the UK's largest retailers and brands, where the work you deliver has a direct and visible commercial effect. Much of the work is new build. The Plan-Apps ecosystem is becoming service oriented and more data centric, with new data warehousing and clearer boundaries between services, so you will be adding to the platform rather than only maintaining what is already there.
What you’ll do
- Build and maintain web application features across the full stack using JavaScript and TypeScript, React and Node.js.
- Take ownership of assigned tickets and deliver them end to end, to agreed quality standards and within the team's established patterns.
- Write clean, secure, maintainable code that others can build on.
- Participate actively in code review, both giving and receiving constructive feedback.
- Contribute to automated test coverage and to improvements in our CI/CD pipelines.
- Support the reliability of our AWS infrastructure with guidance from senior engineers.
- Apply security and performance fundamentals in day to day development decisions.
- Work closely with QA and Product to make sure tickets are well understood, testable and production ready.
- Build depth in the codebase and the commerce media domain over time.
- Contribute to new services as they are built out, and to the data centric patterns being adopted across the platform.
What we’re looking for
- Hands on software engineering experience in a professional, commercial environment.
- Solid working knowledge of JavaScript with practical exposure to TypeScript, and real experience in React and/or Node.js.
- Practical experience working with databases; exposure to MongoDB or another NoSQL store is an advantage.
- Comfortable deploying to a cloud environment, ideally AWS or Azure.
- Confident with Git, branching, pull requests and code review workflows.
- Exposure to CI/CD pipelines and automated testing practices.
- Understanding of web application security and performance fundamentals.
- Clear communicator who collaborates well inside an agile delivery team.
Desirable:
- Experience with relational databases such as PostgreSQL alongside NoSQL, or genuine interest in working with both.
- Familiarity with Infrastructure as Code concepts such as Terraform.
- Exposure to containerised deployment, for example ECS or Kubernetes.
- Awareness of observability practice: logging, monitoring and tracing.
- Interest in or exposure to retail media, ad tech or media measurement platforms.
We're looking for people who enjoy the buzz of change, the satisfaction of building something better, and the joy of working with a close-knit, values-driven team. If you love variety, thrive in a fast-paced environment, and embrace change with energy, this could be your right role.
Don’t meet every single requirement? We still want to hear from you. If you believe you’d thrive in this role, your unique perspective might be just what we’re looking for.
Why SMG?
At SMG, we hire for the future, which is fast-moving and changing shape. Do you have the potential to help shape our business? We’re looking for brilliant, diverse talent who want to grow with us - people who are curious, ambitious, and eager to learn, whether as specialists or across teams.
We value those who take ownership of their growth and bring fresh perspectives. That’s why we’re committed to equity, inclusion, and building a place where everyone feels empowered to grow. At SMG, it’s not just about filling a role but building the future together.
- 10% discretionary bonus
