Seccl is the Octopus-owned embedded investment platform that’s on a mission to helping more people to invest – and invest well. We’re B-Corp certified with an amazing product-market fit, impressive early traction and the potential to transform an outdated industry, for the better. We've been growing fast and will scale even faster over the next few years. We’re also proud to be part of Octopus, the £multi billion group that's on a mission to breathe new life into broken industries, through companies like Octopus Energy, Octopus Investments and Octopus Money.
The Role
We're looking for a Senior DevOps Engineer to shape and evolve the platform that underpins our investment products. You’ll be someone who loves understanding engineering problems and enabling teams to self-serve their needs. You view the cloud platform as a product, and engineering as your customer. The role is within our Cloud Resilience team—a critical squad within our engineering organisation responsible for empowering squads to build and run their own services.
We’re primarily in AWS, utilising Lambda, ECS, SQS, API Gateway among others. Our database engine is MongoDB and our observability platform is Datadog. Our application is written in Typescript/NodeJS and our infrastructure is defined in Terraform.
Key Responsibilities
Architect, implement, and maintain scalable, secure infrastructure in AWS using Terraform.
Design cloud-native solutions using MongoDB, Lambda, API Gateway, and other AWS services with a strong focus on serverless.
Contribute to incident response efforts, production readiness, and reliability initiatives across engineering squads.
Enhance observability and platform insight through actionable alerting and data visibility using Datadog.
Continuously improve CI/CD processes with GitHub Actions, reducing friction in delivery pipelines.
Collaborate with software engineers (working in Node.js/TypeScript) to ensure secure, performant, and resilient applications.
Mentor engineers and champion DevOps culture and best practices across teams.
Required Qualifications
This role’s for you if...
You’re a pragmatic DevOps engineer with experience in regulated environments, balancing delivery with compliance and operational excellence.
You’re confident working with JavaScript/TypeScript-based applications and collaborating closely with development teams.
You know what “good” looks like for databases like MongoDB and can diagnose, design, and optimise for scale and resilience.
You care deeply about observability—you don’t just monitor systems, you build alerts that engineers can act on.
You’re fluent in AWS best practices, infrastructure-as-code (Terraform), and CI/CD tooling like GitHub Actions.
You’ve had exposure to architectural decisions and willingness to own of platform-level outcomes.
