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Until now, insurance has been making billion-dollar decisions using outdated tools.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.
The Customer and Consulting team sits at the heart of how hx delivers lasting value to its clients. As hx continues to expand across global carriers, reinsurers, and specialist MGAs, this team ensures that customers don't just adopt the platform, they transform the way they price and underwrite risk. The post-sale Solution Architect is a critical part of that mission, responsible for making sure the hx platform is deeply embedded in customer ecosystems, from reporting pipelines to security infrastructure and third-party integrations.
This is a team that operates at the intersection of technical depth and customer partnership. The work is hands-on and high-stakes: translating complex customer environments into durable, scalable technical solutions, while building the kind of trusted relationships that drive adoption, margin, and long-term value. You will work closely with Customer Success and Delivery colleagues, acting as the technical anchor across multi-threaded customer engagements.
The team is growing, and there is real scope to shape how the Solution Architect function scales. Whether you are designing AI-first delivery artefacts, contributing reusable patterns to a shared toolkit, or presenting architecture decisions to a Chief Information Officer, your work will directly influence the outcomes customers achieve, and the reputation hx builds in the market.

Own the technical relationship with a portfolio of strategic customers, becoming the trusted advisor who anticipates challenges, aligns delivery to outcomes, and ensures the hx platform is embedded confidently within each customer's ecosystem.
Design and deliver bespoke integrations between hx and a range of customer technologies, including policy administration systems, data warehouses, BI tooling, and identity providers, applying sound architectural judgement throughout.
Drive customer adoption and platform usage by developing structured value realisation plans that translate technical delivery into measurable business outcomes, including faster quote turnarounds, reduced pricing errors, and stronger MI capability.
Build AI-first consulting and delivery artefacts that raise the bar for how the team works, creating reusable frameworks, templates, and innovation outputs that can be shared across the broader SA toolkit.
Support project margin outcomes by managing delivery scope, surfacing risks early, and coordinating effectively with Customer Success Managers, Delivery Leads, and customer-side technical teams.
Contribute to team capability by sharing patterns, leading internal show-and-tell sessions, and helping to codify best practices as the Solution Architect function grows and scales.
Able to code to a high standard using Python.
Supported the technical delivery of SaaS platform integrations in a team setting. It’s beneficial if you also have experience with AWS architecture, SQL, and a foundational understanding from a computer science or software development background.
Built and maintained positive technical relationships with colleagues and stakeholders, including IT and data teams, by communicating effectively across different priorities and environments.
Helped communicate technical choices and delivery progress to non-technical stakeholders, using clear, outcome-driven explanations that link integration work to business value.
Gained experience in a post-sale or customer-facing technical role—such as Junior Solution Architect, Technical Support, or Implementation Analyst—where you supported the delivery process or customer needs.
Used AI or automation tools to enhance the quality, speed, or consistency of your work, with an understanding of where these technologies can add value.
Supported the management of delivery processes, such as helping to plan project phases, identify risks, or coordinate with internal or external teams to meet project timelines.
You prefer to stay in a narrow technical lane and hand off customer communication to others; this role requires genuine ownership across both the technical design and the stakeholder relationship.
You need a fully defined brief before getting started; ambiguity is a constant here, and the best work comes from people who move confidently without waiting for perfect information.
You measure success by delivery completion rather than customer outcomes; at hx, adoption, margin, and measurable value are the real bar.
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.
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.
Because we're building at the intersection of technology/SaaS and insurance, our roles don't always map neatly onto traditional benchmarks. Our approach is to design compensation that's competitive in the market, fair across teams, and aligned with the impact our people make.
Equity: We offer equity across all roles at hx, making it a significant component of total compensation. Your Talent Partner will be able to share more details about this.
