Senior product experience designer

Ongoing contract role · 10 hours per week · Remote (Brazil Based) Flexible hours · PST time zone overlap preferred International team across Brazil and North America 5+ years of designing Saa S web applications (required) Hands-on product experience design - workflows, flows, wireframes Fluent English required - written and spoken About the Role We're looking for a Senior Product Experience Designer to help shape the user experience of a Saa S web application platform that supports healthcare practitioners in delivering better patient outcomes. This role is intentionally scoped at 10 hours per week, with some overlap during PST business hours required. It's focused on senior-level product experience design - the kind of work where judgment, clarity, and good decisions matter. This role is well suited to someone who: enjoys focused, high-impact work, may already have other professional commitments, and values collaborating with a small, international team on meaningful product problems. You'll work closely with the founder and an experienced product, design, and development team to design end-to-end product experiences — from early concepts through to wireframes ready for visual design and implementation. This is not a UI-polish role, and it's not advisory. You will be designing the product experience itself. About Optive We build software that helps functional medicine and healthcare practitioners deliver better patient outcomes through clearer data, better insight, and more consistent follow-up care. Optive is the next stage of this work - a patient engagement and care platform designed to support ongoing, relationship-based healthcare rather than one-off interactions. Our team works across two closely related platforms: Optive - a patient engagement and care platform Optimal DX - an established diagnostics and lab interpretation system used by practitioners today You'll contribute experience design work across both platforms, helping ensure coherence and clarity as the ecosystem evolves. Our team is fully remote and international, working across Brazil and North America, with collaboration primarily across PST time zones - often a good fit for Brazil-based team members who prefer some evening overlap. What You'll Do Design end-to-end user journeys for complex Saa S web applications Translate product goals into clear workflows, flows, and wireframes Think through user intent, edge cases, and complexity vs. simplicity trade-offs Create low-fidelity wireframes and experience diagrams (Figma, Miro, etc.) Collaborate with a senior visual designer who will take your work into high-fidelity design Challenge assumptions constructively and improve product clarity early - before development begins Communicate clearly with an international team in English, both written and spoken Why this Role Might be a Fit Have 5+ years of experience designing customer-facing Saa S products or complex web applications Have worked on products that real customers use in production Are comfortable designing multi-step workflows and role-based experiences Understand how UX decisions impact usability, adoption, and real-world outcomes Prefer focused, senior-level contribution over full-time availability Are comfortable working independently with a high level of trust Can overlap some working hours with PST Communicate fluently in English Preferred Background While we care far more about what you've designed and shipped than your exact job title, this role is best suited to someone who has: Designed complex Saa S or web applications used in production Owned or heavily influenced end-to-end product experiences, not just individual screens Worked closely with founders, product leaders, or engineering teams in small to mid-sized software companies Designed workflows where clarity, trust, and correctness matter (e.g. healthcare, fintech, B2 B, or data-heavy products) Been accountable for experience decisions that had real user and business impact If your experience is primarily marketing sites, brand work, or UI-only execution, this role is unlikely to be a fit. Proof Matters We strongly prefer candidates who can show real work, such as: Screenshots of shipped Saa S products Annotated flows or wireframes Case studies explaining experience design decisions Clear examples of problems you personally solved We understand NDAs exist — but we're looking for people who can point to real experience design work and talk concretely about the decisions behind it.

Please include: A short note about your experience designing Saa S or web applications Links to relevant work (portfolio, screenshots, case studies) Anything that clearly shows how you shaped the product experience Applications without clear experience in Saa S or web-based product design will not be considered.
