Company mission
Seccl is the Octopus-owned embedded investment platform that’s helping more people to invest – and invest well.
Role
Who you are
- You’re a pragmatic platform 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 Postgres 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
- If this sounds like your kind of thing, we encourage you to apply even if you don’t tick every box. We’d love to hear from you!
What the job involves
- We're looking for a Platform 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, EventBridge, API Gateway, Aurora, Redshift among others. Our main data store is MongoDB Atlas and our observability platform is Datadog. Our application is written in Typescript/NodeJS and our infrastructure is defined in Terraform
- Architecting, implementing, and maintaining scalable, secure infrastructure in AWS using Terraform
- Designing cloud-native solutions using MongoDB, Lambda, API Gateway, and other AWS services with a strong focus on serverless
- Contributing to incident response efforts, production readiness, and reliability initiatives across engineering squads
- Enhancing observability and platform insight through actionable alerting and data visibility using Datadog
- Continuously improving CI/CD processes with GitHub Actions, reducing friction in delivery pipelines
- Collaborating with software engineers (working in Node.js/TypeScript) to ensure secure, performant, and resilient applications
- Mentoring engineers and champion DevOps culture and best practices across teams
Application process
- Interviewing is a two-way thing, and we want you to have the time and opportunity to get to know us, as much as we are getting to know you. Our interviews are conversational, so come with questions and be curious. In general, you can expect the interview process to look a bit like this, (following an initial chat with one of our Talent team):
- First stage – 60 mins Cloud System Design interview
- Second stage – 60 mins Terraform Code Review Interview
- Final stage – 45 mins bar-raiser culture-based interview
- ⏳ We’ll only close this role once we have enough applications for the next stage. Please submit your application as soon as possible to make sure you don’t miss out and you should expect to hear back from us within one to two weeks of applying
