About Hyperexponential (hx) At hyperexponential, we’re building the AI-powered platform that enables the world’s most critical decisions in a $7 trillion industry - which risks to take, and how to price them. These are the decisions that shape real-world outcomes: whether rockets successfully launch into space, autonomous vehicles make it to market, or communities recover after major storms.

Until now, insurance has been making billion-dollar decisions using outdated tools. We’re changing that. Our platform brings together data, AI, and human expertise to give insurers the fastest path from submission to decision - helping them move faster, act smarter, and take on more risk with confidence.

Backed by a16z, Highland Europe, and Battery Ventures, we’re scaling globally - already trusted by nearly 50 of the world’s largest insurers, with zero churn and billions in premiums flowing through hx.

What began as a single product in one market has rapidly evolved into a multi-product, multi-territory platform powering every stage of pricing and underwriting. AI is at the core of what we do - from building the world’s first domain-specific AI peer programmer for insurance (think GitHub Copilot with a PhD in actuarial science) to shaping agentic workflows that reinvent how this industry operates.

What makes hx different is the people who build it. Here, impact isn’t tied to title or tenure; it’s defined by the challenges you take on and the discipline you bring. Surrounded by peers who stretch you, you’ll do the best, hardest work of your life in a company engineered to endure.

If that sounds like you, join us in building what comes next.

About The Solutions Architecture Team Field Engineering (FENG) is the technical core of our go-to-market organisation. The team sits at the intersection of product, sales, and customer success, owning the “technical win” in each deal and making hx Renew real for some of the most demanding insurers in the world. We work with underwriters, actuaries, IT, and security leaders to design solutions they can trust with their most critical pricing and underwriting decisions.

This is a team that thrives at the edge of what’s possible for our product and our customers. We specialise in the hardest integration and implementation challenges, where deep technical understanding, domain insight, and creativity are all required. As a Senior Solutions Architect, you’ll be one of the first hx’ers many prospects meet, shaping how they understand our platform and what it can do for their business.

The culture is high-ownership, collaborative, and very visible: every engagement is high stakes, every interaction leaves a lasting impression, and your work feeds directly into both revenue outcomes and product direction. You’ll partner closely with Sales and Product Engineering, acting as a trusted advisor throughout the sales cycle and beyond, and helping customers realise the full value of hx Renew.

What You’ll Be Doing

• Accelerate time-to-value by translating prospect requirements and legacy constraints into clear, actionable integration approaches aligned to our onboarding and integration playbooks.
• Run focused, high-impact technical discovery and design workshops with underwriters, actuaries, and IT stakeholders to deeply understand their workflows and shape viable solution architectures.
• Act as the trusted technical voice throughout the sales cycle, guiding stakeholders through RFPs, RFIs, due diligence, and security reviews to remove friction and keep deals moving.
• Design, build, and present compelling proofs-of-concept and demos that showcase hx Renew’s integration capabilities and how we can transform customers’ pricing and underwriting processes.

What You’ll Need To Have Done

• Led technical solution design and integration for complex B2B or enterprise software deals, ideally in data-heavy domains
• Run end-to-end technical evaluations with multiple stakeholder groups (e.g. business, IT, security), successfully navigating RFP/RFI processes, due diligence, and technical Q&A to a clear “tech win”.
• Designed and documented solution architectures within known patterns (e.g. APIs, event-driven integrations, identity and access management), clearly articulating assumptions, risks, and trade-offs.

Bonus: experience or familiarity with insurance

You’re unlikely to thrive here if

• You prefer to follow a fixed, prescriptive playbook rather than dealing with ambiguity, evolving requirements and messy legacy environments.
• You’re uncomfortable being highly visible – with customers, internally with senior stakeholders, and in situations where the stakes (and expectations) are high.
• You see yourself purely as either “sales” or “engineering” and don’t enjoy operating in the grey space between commercial outcomes, technical depth, and product thinking.

If reading our Culture Document leaves you feeling neutral rather than energised, hx may not be the place where you’ll do your best work. We’re building something that asks for commitment and conviction, and we want you to feel excited by the opportunity to grow with us.

Compensation At hx, we’re committed to salary transparency. You’ll always have clarity on pay early in the process - our Talent Partner will share details with you during initial conversations - and we’re working towards publishing salary information for all roles globally.
