Our engineering ways of working:Our Product and Engineering organisation is structured into four tribes: Custody, Accounts, Experience, and Cloud & Security. Each tribe contains multiple autonomous squads, with clear full ownership over specific product domains.
The squads are intentionally small and cross-functional, typically made up of an Engineering Manager, Product Manager, and 3–5 engineers with complementary skills aligned to the domain they own.
We operate in a build-and-run model, with teams responsible for the full software lifecycle, from architecture and delivery through to operational support and incident management.
Our core platform is built on AWS serverless technologies including Lambda, SQS, EventBridge, API Gateway, S3, and ECS. We primarily develop in TypeScript and Node.js, with MongoDB as our primary document database. We also have a small number of C# services and are continuing to evolve our platform architecture, including expanding our use of ECS Fargate.
Infrastructure is managed through a combination of Terraform and Serverless Framework. We use GitHub Actions for CI/CD and incident.io to support our incident management processes and operational workflows.
We care deeply about engineering quality, pragmatic architecture, and continuous improvement. If you’d like to go deeper, we’re happy to share more about our engineering practices and technology radar during the interview process.
As an engineer at Seccl you will design, build and operate reliable and scalable, testable and maintainable software solutions, building new functionalities and products using Typescript and Node.js. You play a key role in our software development and have a hands-on approach throughout the development process supporting resilient financial workflow systems and regulated investment operations. As a senior member of the team, you are the ‘go-to’ person for queries.
