[Hiring] Senior Software Engineer @Seccl

Role Description

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.

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.

On a typical day you will:

• 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.

Qualifications

• 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.

Requirements

• 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.
