Collinson Group - Backend Lead Engineer - TypeScript/Node.js

Posted on: 10/12/2025

Job Description

Description :


- As a Lead Engineer, youll be the technical backbone of your squad (of around 5-7 engineers) - leading from the front, writing code daily, and setting the standard for high-quality engineering.

- Youll work side by side with an Engineering Manager, ensuring your squad is delivering scalable, well-architected software, while collaborating closely with a Product Manager to build and launch new products and services as a partnership.

- This is a hands-on role, with a strong focus on designing, coding, and problem-solving.

- Youll be the most experienced engineer in the squad, responsible for refining technical requirements, making key architectural decisions, and mentoring engineers to help them grow.

- With modern, cloud-native technologies (including Typescript, AWS, GraphQL) and the freedom to approach problems with fresh thinking, youll be building greenfield systems from the ground up.

- Expect to embed AI, automation, and best-in-class engineering practices into everything you develop.

- If you love writing great code, solving complex technical challenges, and shaping the direction of a team, this role gives you the autonomy, responsibility, and impact to do just that.

Knowledge, skills and experience required :


- Tech stack - We use TypeScript (Node.js & React), AWS (EKS, Lambda, Aurora RDS), Kubernetes, GraphQL, Kafka, Mongo. Youre comfortable with all of these, and have extensive knowledge of JavaScript more generally, the AWS ecosystem, and running containerised applications.

- Past Experience - You are currently a Lead Engineer or Tech Lead, leading a small team of software engineers.

- API & Database Development - You have experience building and running robust, always-on APIs (both RESTful and GraphQL-based) and underlying services/apps including the databases that underpin them.

- Test-Driven Development - You're very familiar with testing frameworks such as Jest and Pact.

- Cloud & DevOps - You can build, deploy and run your systems end-to-end, with no manual configuration or intervention. We use Terraform and Helm.

- CI/CD - You have plenty experience managing and configuring CI/CD pipelines (we use GitHub Actions) for deployments.

- Observability Mindset - You believe in measuring everything. Youve worked with DataDog (or similar) to ensure your team has the necessary visibility into system health.

- Tooling & Collaboration - Comfortable working with Git, Confluence, Jira, and modern engineering workflows.

- Mentorship & Leadership - Youve mentored engineers at all levels, providing guidance, reviewing designs, and ensuring your team stays on the right track.

- Self-Starter & Problem-Solver - Ability to take a product challenge and develop a working technical solution, balancing pragmatism with engineering excellence
