London or US | Full-time | Reports to VP, Solution Architecture
ABOUT ACCELERANT
Accelerant is a Risk Exchange that connects underwriting talent with capacity. We combine proprietary data, technology, and deep insurance expertise to help members build and scale specialist insurance businesses. We are growing quickly and investing heavily in the platforms and capabilities that underpin our exchange.
ABOUT THE ROLE
Accelerant is in an exciting period of growth and transformation. We are modernising our platforms, expanding our data capabilities, and embedding intelligent automation across the business - all at pace. Solution Architecture sits at the centre of that effort, connecting technology decisions to business outcomes across underwriting, claims, finance, and operations.
This is a hands-on role. You will be embedded in delivery squads, owning the design end-to-end from requirements through to go-live - not handing off a diagram and stepping back. The quality of your upfront design work directly determines whether delivery runs smoothly or stalls, so thoroughness and attention to detail matter as much as the ability to think at a high level. You will report directly to the VP of Solution Architecture.
WHAT YOU'LL DO
• Own the design of integration and platform solutions from requirements through to delivery, working across a wide variety of programmes and business domains.
• Gatekeeper requirements before design begins - ensuring functional scope is clear, agreed, and documented before a squad is formed or build starts.
• Produce design documentation thorough enough for developers to build from and testers to derive test targets from, without needing to escalate back to you for answers.
• Stay embedded in delivery squads through build and test, providing design authority when questions arise rather than being pulled in retrospectively to firefight.
• Translate complex business requirements - from underwriting, claims, finance, and operations - into clear, actionable technical designs, using MuleSoft as the primary integration platform.
• Work alongside data, platform, and product engineering teams to define connectivity patterns across event-driven, API, and file-based channels.
• Contribute to architecture governance, ensuring integration decisions are made at the right point in delivery rather than discovered mid-sprint.
• Support the adoption of AI-native development tooling and emerging integration capabilities as we modernise how we build.
WHAT WE'RE LOOKING FOR
Essential
• Proven experience as a solution architect or lead integration developer, with MuleSoft as your primary integration platform.
• A track record of seeing designs through delivery, not just producing them - you have been the person in the room when things get difficult, and you have the scars to show for it.
• Solid understanding of insurance or reinsurance operations - you can hold a substantive conversation with underwriters and claims managers, not just engineers.
• Comfort working in ambiguity: you can move a design forward when requirements are still forming, and you know when to decide vs. when to ask.
• Strong requirements discipline - you push back when scope is unclear before build starts, because you know what happens when you do not.
• Strong business translation skills - the ability to understand what a stakeholder actually needs and express it as a workable design, not just a literal interpretation of the ask.
• Experience producing formal architecture documentation (design specifications, integration records, data-flow maps) at a level of detail that delivery teams can genuinely use.
• Familiarity with event-driven and API-led connectivity patterns.
Preferred
• Hands-on experience with Snowflake, Redpanda (or Kafka), and Dynamics 365 / Dataverse.
• Exposure to Microsoft Fabric, Azure Service Bus, or AWS.
• Awareness of AI-native development approaches - agent-assisted coding, LLM-driven integration tooling, or similar.
• Background in Lloyd's market or specialty insurance.
• Experience contributing to or chairing architecture review boards or similar governance forums.
WORKING AT ACCELERANT
We are a globally distributed team building something genuinely new in the insurance market. This role suits someone who gets satisfaction from delivery that runs well - where the design held up, the squad stayed small, and nobody had to be pulled off something else to rescue it. You will have real architectural ownership and direct visibility of the programmes that matter most to the business.
Accelerant is an equal opportunity employer. We welcome applications from candidates of all backgrounds.
