API Architect

This is a great job for someone who enjoys designing how systems connect and data flows across a complex organisation. You might be an experienced integration or API architect who likes balancing big‑picture thinking with hands‑on technical depth, and who’s comfortable influencing across multiple teams and markets. If you enjoy simplifying legacy integration, shaping standards, and enabling modern, cloud‑native platforms, this role could be a great fit.

A bit about the job: The API & Integration Architect designs and evolves Aviva’s API‑led and event‑driven integration landscape, helping ensure systems connect in a secure, scalable, and well‑governed way. The role shapes enterprise integration patterns across cloud, on‑prem, and multi‑market platforms, supporting Aviva’s digital, operational, and data ambitions. Working closely with engineering, security, and architecture teams, you’ll help move the organisation towards more decoupled, resilient, and reusable integration solutions.

Skills and experience we’re looking for:

• API Architecture & Design (Synchronous and Asynchronous) - Ability to design scalable, secure, standards‑aligned APIs—including synchronous request/response and asynchronous/event‑driven patterns to support modern integration across a complex system landscape.
• Event‑Driven Integration & Event Backbone Architecture - Expertise in architecting event streaming patterns, decoupled services, and backbone evolution to reduce system fragility and enable real‑time, domain‑driven data flows.
• Integration Platform & Middleware Engineering - Strong understanding of integration middleware (e.g., API gateways like Kong, event brokers, ETL/ELT, file transfer, RPA integration methods), enabling secure and performant cross‑platform connectivity.
• Cloud‑Native & Container‑Based Deployment Patterns - Knowledge of container orchestration, cloud hosting, zero‑trust controls, and scalable deployment models that underpin resilient integration capabilities.
• API Governance, Security & Discoverability - Skill in defining standards for API security, metadata, cataloguing, observability, versioning, lifecycle governance, and aligning integration practices with enterprise frameworks and CISO policies.

What you’ll get for this role: Our purpose – with you today, for a better tomorrow – is a promise we make to our colleagues too. And one of the ways we live up to that promise is by investing in you. We have so much to offer when it comes to being an Aviva colleague.

• Starting salary £115k circa (London) / £100k circa (National) (depending on location, skills, experience, and qualifications)
• Bonus opportunity – 12% of annual salary. Actual amount depends on your performance and Aviva’s.
• Generous pension scheme – Aviva will contribute up to 14%, depending on what you put in.
• 29 days holiday plus bank holidays, and you can choose to buy or sell up to 5 days.
• Aviva-funded Private Medical Benefit to help you get expert support when you need it.
• Make your money go further - Up to 40% discount on Aviva products, and other retailer discounts.
• Up to £1,200 of free Aviva shares per year through our Matching Share Plan and share in the success of Aviva with our Save As You Earn scheme.
• Brilliantly supportive policies including parental and carer’s leave.
• Flexible benefits to suit you, including sustainability options such as cycle to work.
• Make a difference, be part of our Aviva Communities and use your 3 paid volunteering days to help others.
• We take your wellbeing seriously with lots of support and tools.
