Senior Consultant

Are you an ambitious actuary looking to build your career in P&C actuarial consulting? Do you want to join a high-performing team, working across a broad range of clients and topics, with significant exposure and responsibility to major clients?

This is a hybrid role within our London-based P&C actuarial consulting team, part of Aon’s Strategy and Technology Group (STG).

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 organisation, we are united through trust as one inclusive team and we are passionate about helping our colleagues and clients succeed.

What the day will look like

In this role, a typical day might include:

• Collaborating across the team and Aon: working within a team of ~50 actuarial colleagues in London, alongside wider consulting teams, brokers and specialists from across STG and Aon.

• Client engagement: Act as the main client engagement lead including overseeing communications, managing expectations, and ensuring a high‑quality client experience.

• Project Management: manage end‑to‑end client projects, including scoping, planning, resourcing, and delivery, ensuring timelines, budgets, and quality standards are met.

• Delivery: Ownership of the actuarial results, approach and narrative, from reviewing assumptions, methods and results to crafting the story, ensuring findings are accurate, explainable, and decision‑ready.

• Developing your skills: contributing to research, insight pieces and client materials.

• Coaching junior colleagues: provide coaching to more junior colleagues to develop their technical and consulting skills.

You’ll split your time between our London office and home, depending on client, project and team needs.

How this opportunity is different

This is an opportunity to join a growing P&C actuarial consulting team working with clients across the insurance market, including corporates, captives, insurers, Lloyd’s syndicates, reinsurance groups and ILS entities, across geographies from EMEA to Bermuda. Our work spans capital modelling, reserving, IFRS 17, Solvency II, portfolio advisory, and pricing.

You’ll work closely with a collaborative team of ~50 P&C actuaries in London, from graduates to senior actuaries, with the opportunity to learn from senior colleagues while contributing meaningfully from an early stage. Early in your career with us, we aim to give you broad exposure across different types of actuarial and consulting work, helping you to build rounded judgement rather than narrowing too quickly into a single specialism.

We do not support audit engagements. Instead, we help clients use actuarial insight to make better decisions – whether that means advising on how internal capital models support strategy and portfolio steering, providing experienced actuarial support for business-as-usual activity, or supporting live transactions.

As part of STG, we sit alongside Aon’s actuarial software and technology teams, which develop and support solutions including ReMetrica and Tyche. That means that we help shape how these solutions evolve for clients and act as the principal consulting partner to organisations using our software. Clients are at the centre of what we do, so you’ll have regular client interaction and meaningful exposure from an early stage.

We rarely recruit other than at graduate level, reflecting the team’s strong retention record and the fact that many of our colleagues have developed their careers here from the outset. This role is different: we are hiring at Consultant level to support continued growth in demand for our work.

Skills and experience that will lead to success

This role is likely to suite candidates who have already built a solid foundation in actuarial work and are ready to broaden their experience in a consulting environment

• Technical actuarial expertise: strong grounding in actuarial analysis, with the ability to work with data confidently and apply appropriate methods and assumptions. Comfortable using tools such as SQL, R, Python, alongside Excel and actuarial software, to support high-quality client delivery. Experience with our actuarial software such as ReMetrica or Tyche would be helpful, but is not essential.

• Client‑facing and relationship skills: Professional, credible and collaborative in client settings, with the confidence to ask good questions, contribute to discussions and help build strong working relationships.

• Communication and storytelling: Clear written and verbal communication, with the ability to explain technical work in a concise, client-appropriate way and produce strong reports, presentations and other client-ready output..

• Commercial mindset: Ability to connect analysis to business decisions, with an understanding of client objectives, commercial and market context, and the financial and practical impact of recommendations.

• Judgement and curiosity: Curious and thoughtful in approach, with the ability to challenge constructively, apply judgement proportionately, and keep developing technical and consulting skills over time.

• Collaboration, teamwork and delivery quality: Works effectively with colleagues at all levels, shares knowledge openly, supports more junior colleagues, and contributes to a strong culture of collaboration, peer review and high-quality delivery.

• Project and time management: Able to manage work across multiple projects, prioritise effectively, meet deadlines, and maintain attention to detail while working at pace.
