Job description

Who we are

Apollo is a specialised independent (re)insurer, established in 2009, to deliver top‑tier products and services to clients, brokers, and capital partners at Lloyd’s.

Together with Jim Hays, Neil identified an opportunity to create a unique service provider within Lloyd’s. Since its inception, Apollo has significantly broadened its portfolio of insurance solutions, including Apollo 1969’s traditional and specialty lines, ibott 1971’s innovative sharing‑economy products, and managing agency services at Lloyd’s through our Platform Partner Syndicates. Today, Apollo continues to grow with a team of 300 professionals dedicated to fulfilling the company’s mission of enabling a resilient and sustainable world.

"We attract and retain a diverse range of talent by fostering an inclusive, equitable team environment where individuals from all backgrounds have opportunities to grow, succeed, and contribute. We empower our teams to achieve excellence and drive forward‑thinking solutions, aiming to enable a resilient and sustainable world." - David Ibeson, Group CEO

Your Role

Apollo is modernising its technology landscape with cloud‑based applications, integrations, and automation that support underwriting, operations, and business growth. As a Back‑End Integration Engineer within our Digital Solutions team, you will design, build, and maintain the APIs, services, and integration patterns that connect systems across the organisation.

You will play a key part in creating secure, scalable, and reliable integrations that enhance how data and applications interact. Working closely with colleagues across business and technology teams, you will help shape solutions, streamline processes, and improve end‑to‑end system performance.

What You Will Do

• Design and implement integrations across internal systems, cloud services, and vendor platforms.
• Build and maintain APIs, messaging components, orchestration workflows, and data access layers.
• Apply recognised integration patterns, security standards, and governance principles.
• Contribute to design discussions, architectural patterns, and engineering best practice.
• Develop high‑quality, secure, maintainable code using approved languages and tools.
• Support CI/CD pipelines, automated testing, and code review activities.
• Work within agile delivery cycles to estimate, plan, build, test, and deliver integration work.
• Troubleshoot technical issues and provide early‑life support for new integrations.
• Collaborate with Product Owners, Analysts, Application Engineers, Data Engineers, and Architects to translate requirements into effective solutions.
• Monitor integration performance and identify opportunities to simplify architecture or enhance automation and observability.
• Support governance, security, and compliance requirements across integration components.

What We Are Looking For

• Hands‑on experience designing and building APIs, services, and system integrations.
• Strong understanding of integration patterns including REST, messaging, event‑driven approaches, and orchestration.
• Experience with cloud integration services such as Azure API Management, Service Bus, Event Grid, and Functions.
• Proficiency in C# or Python, with a focus on secure coding practices.
• Experience with CI/CD, automated testing, and modern engineering practice.
• Strong problem‑solving capability and the ability to collaborate across technical and business teams.
• Understanding of data flows, data modelling, and interoperability concepts.
• Experience integrating legacy systems or vendor platforms.
• Knowledge of the Lloyd’s insurance market is beneficial.
• Familiarity with agile delivery and DevOps approaches.

What you will get in return

Our compensation package is designed to attract top talent. In addition to a fair and attractive salary, this role offers a discretionary bonus and a comprehensive range of benefits, including 31 days of annual leave, a non‑contributory pension and private medical insurance.
