AON IS IN THE BUSINESS OF BETTER DECISIONS

At Aon, we shape decisions for the better to protect and enrich the lives of people around the world.

As an organization, we are committed to our purpose as one firm, united through trust as one inclusive, diverse team and we are passionate about helping our colleagues and clients succeed.

GENERAL DESCRIPTION OF ROLE:

As a Senior Software Engineer within the Assessment Solutions business, you will design, build, and deliver core features of the Aon Assessment Platform - the enterprise solution for accurate and fair workforce assessments at scale, used by millions of participants worldwide.

You are a senior individual contributor within one of our international engineering squads (Germany and India), trusted to own the design and delivery of significant features and modules with minimal supervision. You work from Product Requirement Definition (PRD) documents and, in partnership with your Software Engineering Team Lead, turn them into sound technical designs - then build, test, and ship them. You also raise the bar for the engineers around you through code review, pairing, and example.

Our platform is large and deeply interconnected, so strong analytical thinking matters as much as coding skill. You need to understand how your changes ripple across other components and design accordingly, rather than optimising only for the feature directly in front of you.

Key Responsibilities

• Own the design and delivery of significant features and modules end-to-end - from technical design through implementation, testing, and release - with minimal supervision.
• Translate PRDs into clear implementation plans, contributing directly to Technical Specification Documents (TSDs) alongside your Team Lead.
• Write clean, well-structured, well-tested code across the stack: C#/.NET services, SQL Server data access, and react front-ends.
• Identify edge cases, failure modes, and non-functional requirements (performance, security, accessibility) early in design - not after code review.

• Conduct thorough code reviews that raise the quality bar for the whole squad - checking not just correctness but architectural fit, testability, and maintainability.
• Champion and apply engineering standards: layered architecture, OpenAPI-first API design, and our React corporate design system.
• Write and maintain automated tests (unit, integration) as a core part of delivery, not an afterthought.
• Investigate and resolve complex bugs and production issues that require deep platform knowledge to diagnose.

• Map how your changes interact with other components of the platform, flagging cross-team dependencies and risks early.
• Work closely with your Team Lead, Solution Architects, QA, and Business Analysts to clarify requirements, resolve ambiguity, and validate designs before implementation.
• Participate actively in technical design reviews - both presenting your own designs and providing rigorous, constructive feedback on others.
• Support integration efforts with other squads and systems (ATS integrations, shared services) where your modules are involved.

• Mentor and unblock less experienced engineers - through pairing, code review, and informal technical guidance - without formal management responsibility.
• Help new engineers onboard to the platform's architecture, standards, and ways of working.
• Contribute to evolving team practices, tooling, and technical standards based on what you learn from hands-on delivery.

• Use AI tools in your day-to-day work - for design exploration, coding, testing, code review, and documentation - and apply them effectively and responsibly. This is a core expectation, not a nice-to-have.
• Identify opportunities where AI-assisted development can improve code quality and delivery speed for your squad.

Required Skills & Experience

• 4-8 years of professional software engineering experience, ideally on a large-scale SaaS or enterprise platform.
• Strong hands-on experience with C#, ASP.NET / .NET Core / MVC, SQL, JavaScript, and React.
• Proven ability to own the design and delivery of non-trivial features end-to-end with minimal supervision.
• Solid understanding of database design, querying, schema design, and query optimization.
• Experience integrating systems via APIs, with comfort working against OpenAPI specifications.
• Strong analytical thinking - able to reason about the downstream impact of design and implementation decisions on an interconnected platform.
• Demonstrated experience conducting thorough, constructive code reviews.
• Good communication skills, and comfortable working in an international team across time zones.
• Day-to-day use of AI tools in engineering work. This is a core expectation, not a nice-to-have.

Nice to Have

• Experience with our cloud and delivery stack: Azure, AKS (Kubernetes), and Azure DevOps CI/CD.
• Exposure to the OpenAPI governance approach we follow.
• Experience mentoring junior engineers or leading small technical initiatives.
• Familiarity with automated testing frameworks and CI/CD-integrated quality gates.
• Exposure to HR technology, talent assessment, or recruitment platform domains.
