What you’ll do :
Being a Technical Lead Engineer is about far more than delivering software. It’s your opportunity to help set the technical direction behind scalable, reliable platforms.
You’ll:
Lead the technical design and delivery of platform and microservices solutions from discovery through to production, making pragmatic architectural decisions that balance quality, pace and long term value.
Stay hands on with TypeScript and Node.js, developing critical platform capabilities and stepping into complex code or production issues when the team needs your expertise.
Own and shape the technical roadmap alongside senior engineering colleagues, ensuring engineering decisions support the wider product and business vision.
Design and evolve AWS based, event driven solutions using services such as Lambda, API Gateway, SNS, SQS, EventBridge, DynamoDB, RDS, S3 and CloudWatch.
Lead technical discovery and produce clear design documentation, including RFCs and Architecture Decision Records, so that decisions are understood, and knowledge is shared.
Raise engineering standards through code reviews, coaching, technical mentoring and practical examples of clean, secure and testable development.
Strengthen testing across the engineering lifecycle, from unit and integration testing through to contract, end-to-end and automated functional testing.
Improve CI/CD pipelines, infrastructure as code practices, release strategies and quality gates, making it easier for teams to deliver safely and consistently.
Champion operational excellence through observability, alerting, incident response, service-level thinking, and structured learning from production issues.
Who you are It’s your unique ingredients we’re interested in. You’ll bring
Deep hands on experience with TypeScript, Node.js and the modern JavaScript ecosystem.
Strong experience designing and delivering platform or microservices solutions, including API design, service boundaries, versioning, compatibility and integration patterns.
Substantial knowledge of AWS services and cloud architecture, particularly serverless and event-driven systems.
A strong understanding of event driven design, including idempotency, retries, dead-letter queues, message ordering and eventual consistency.
Confidence working with SQL and NoSQL databases, including schema design, partitioning, performance and consistency of trade-offs.
Practical knowledge of software architecture and engineering principles, including OOP, SOLID, domain-driven design, and CQRS.
Experience with infrastructure as code, using tools such as Terraform or the Serverless Framework, alongside modern CI/CD and release approaches.
A track record of owning testing strategy and building reliable automated pipelines with appropriate quality gates.
A security first mindset, with a good understanding of secure software development and dependency vulnerability management.
Experience leading technical discovery, influencing engineering decisions and explaining complex subjects clearly to both technical and non-technical stakeholders.
The credibility to mentor engineers, challenge constructively and raise standards without losing sight of delivery.
A collaborative, practical and solutions focused approach, with the confidence to take ownership and follow decisions through.
Experience within retail, vending, connected devices or telemetry would be valuable but isn’t essential.
Exposure to Python, Vue.js, React, .NET or Azure would also be an advantage.
Where you’ll work
You’ll be based at our Sofia Costa office, working closely with colleagues across our Global Technology function.
Here at Costa Coffee, we encourage the sharing of diverse thoughts and ideas. We approach our work fearlessly and support one another in taking a few risks. We learn and grow constantly. Individuality is championed, and we provide a culture where everyone feels included. You can be you at Costa Coffee.
