What you'll do
- Build an engaging path from first interest to a useful result, connecting landing pages and product demonstrations to sign-up, account setup and the first session; measure abandonment and address causes.
- Design a migration experience customers can follow, making upload progress, missing information, validation errors and next steps understandable.
- Develop the design language, navigation and reusable components used across the product, making tables, forms and reports behave predictably including loading, empty and error states.
- Design decision screens that help customers compare recommendations, understand costs and choose what happens next.
- Build interfaces that earn trust: show where a figure came from, explain proposed changes and support review before approval, including accessibility, keyboard use and clear language.
- Keep up with the customer pipeline, observe customer sessions, work with the customer-facing team, turn recurring questions into product changes and check whether they helped.
- Use AI coding agents to implement changes, review the code and verify the finished experience.
- Step in when sign-up, migration or a critical financial workflow breaks, establish what the customer needs and work with the team to restore a safe path forward.
- Respond promptly and stay engaged during urgent issues affecting SLAs, onboarding commitments or financial deadlines, including agreed on-call coverage and coordinated incident response.
- Improve the system after incidents so the same emergency becomes less likely.
- Carry work from customer observation through implementation and release, then follow up on performance.
- Pick up the most important work or whatever is on fire, including tasks outside your specialty.
What we're looking for
- Five or more years of experience designing and shipping software, including B2B SaaS.
- Product design across information architecture, interaction design and visual design.
- Production front-end work with React, TypeScript, CSS and reusable components, including reviewing and debugging code generated by agents.
- Building or maintaining a design system that other people use.
- Customer research, usability testing and product analytics that inform what you ship.
- Daily use of AI coding agents, with a clear approach to specifications, review and verification.
- Clear written explanations of design decisions and their trade-offs.
- Ability to show a product journey you improved, explain the choices you made and describe the effect on customers.
- Experience owning an onboarding, activation or conversion measure.
- Willingness to work flexibly beyond normal working hours as part of agreed on-call coverage and coordinated incident response.
Nice to have
- Financial software, complex tables and dashboards, or products where people need to inspect the source of a result.
- Experience with configuration-driven interfaces, where shared rules and data determine how a screen is assembled.
