hyperexponential - Senior Model Developer (Client Education)
Requirements
• Built deep hx platform expertise and production-grade Python, including testing, deployment and model lifecycles. • Have excellent pricing and modelling judgement when working with customer’s - working with insurance & actuarial teams is a plus. • Developed strong technical enablement instincts, pitching sessions and documentation at the audience's real level. • Coached customer teams to work independently rather than solving problems for them. • Operated with high ownership and self-direction, building repeatable process where none exists. • Prioritised transparently across competing delivery, review and content demands. • Communicated with credibility and clarity across developers, actuaries, delivery partners and internal stakeholders. • YOU'RE UNLIKELY TO THRIVE HERE IF • You prefer following detailed instructions rather than experimenting and finding your own approach. • You are uncomfortable working directly with non-technical stakeholders to understand their challenges. • You avoid tackling ambiguous or open-ended problems where the solution isn't obvious.
Responsibilities
• Move customer teams from hx-led build to independent delivery, shifting effort from pairing toward review and advisory. • Keep every engagement moving to its prescribed path, sequencing services to each customer's build stage. • Deliver structured enablement sessions — architecture, coding best practice, testing and deployment, model lifecycles — pitched at each team's level. • Run code review as a consistent, standards-anchored service, evolving hx's model development standards where reviews expose gaps. • Provide drop-in support shaped by each customer's build stage, resolving most issues in session rather than escalating. • Make Developer+ repeatable rather than personality-dependent, documenting delivery and using AI to scale capacity. • Convert delivery knowledge into hx Academy content, prioritised by what reviews and drop-ins actually surface. • Act as the technical voice of the customer into Product, feeding back recurring friction on a regular rhythm.
