Company mission
Seccl is the Octopus-owned embedded investment platform that’s helping more people to invest – and invest well.
Role
Who you are
- To own your services from design to operation. We operate a build-and-run model where engineers have autonomy but full accountability
- We care deeply about correctness, resilience and operational excellence because our systems underpin real customer investments
- Engineers are not passengers in their products but champions. Drive improvements and features while collaborating openly with product, operations and engineering colleagues, challenging ideas constructively and focusing on delivering the best outcomes for customers
- Have a strong ability to understand business and customer problems and turn them into efficient, scalable solutions. Be curious about how investment and custody products operate, and pragmatic in balancing customer value, operational correctness, engineering quality and long-term scalability
- Experience building financial systems with multi-region, multi-currency or trading-related complexity would be advantageous
- Experience in a strongly/statically typed language
- Have a strong understanding of designing, building, and running high-quality, standards-compliant workflow APIs, with a focus on testing, observability, and performance
- Have worked with a cloud provider (AWS/Azure/GCP). We use AWS
- Have worked with distributed systems and are comfortable debugging through tracing and observability
- Willing to be on-call for your services
- Strong commercial experience with Node.js, specifically TypeScript
- Experience with Amazon Web Services
- Experience with Serverless products
- Experience with document databases, ideally MongoDB
- Experience mentoring engineers
- Experience leading technical delivery in a build-and-run engineering model
- Experience in a structured on-call process and incident management
- Experience working in regulated industries, ideally financial services or FinTech
What the job involves
- This role is remote within the UK, and we're looking for engineers available quickly to join us for 6 months under O/IR35 requirements
- 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
- Work collaboratively in a domain aligned cross-functional squad made up of engineers and product along with colleagues from customer-facing and operations teams
- Design, implement and operate your services within your domain
- Be accountable for the SLAs of your products and iterative improvements
- Maintain and extend documentation for your services
- Foster a culture of continuous improvement and technical excellence while understanding when “good enough for now” is appropriate
- Provide guidance and mentorship for other engineers
- Communicate with non-technical colleagues to answer queries about the Seccl system

With this, Seccl is well on track to power even more businesses, and as it continues to grow, its mission to disrupt the industry with smarter, scalable solutions is only growing in momentum.
