About Certara
Certara accelerates medicines using proprietary biosimulation software, technology, and services to transform traditional drug discovery and development. Its clients include more than 2,000 biopharmaceutical companies, academic institutions and regulatory agencies across 62 countries.
What we are trying to solve
TFL Studio is a core part of our platform--used by clinical and statistical teams to create analysis-ready outputs at scale. It is still growing, and we are now entering a phase where the product needs deeper workflows, clearer patterns, and expanded capabilities that help users do more while maintaining consistency and confidence.
This role is not about reinventing TFL Studio. It is about building on the foundations already in place, extending the patterns we have established, and continuing to evolve the product with clarity and purpose. You will take the baton and lead the next stage of its growth.
As we build a larger platform around TFL Studio in 2026, we also need someone who can ensure that the features we add now will fit cleanly into the broader product ecosystem. This is a secondary responsibility--acting as a design partner to ensure alignment across products--while your primary focus remains on expanding TFL Studio itself.
Responsibilities:
What you will be doing
Your main responsibility will be to design, deepen, and scale the TFL Studio experience.
You will:
Own and expand TFL Studio
Lead the end-to-end UX for TFL Studio, shaping its next generation of workflows, configuration tools, and automation experiences.
Build on the patterns already established--extending them, not replacing them--so the product grows in a consistent, predictable manner.
Translate complex user needs into clear interactions that help users confidently configure, generate, and manage analysis outputs.
Create content, flows, and design decisions that reduce cognitive load for technical and non-technical users around the world.
Work closely with engineering to refine requirements, resolve edge cases, and ensure implementation fidelity through iterative development.
Identify opportunities to scale patterns, simplify workflows, and elevate product clarity without disrupting established foundations.
Ensure TFL Studio fits into our evolving platform
Collaborate with another product designer to align TFL Studio with new platform components planned for 2026.
Evaluate upcoming TFL Studio features through a platform lens--ensuring they work within shared patterns, navigation, and mental models.
Contribute to discussions on cross-product consistency, but without owning the design of the new products themselves.
Surface opportunities where shared components or patterns can support both TFL Studio and future modules.
Advance the design system and branding
Use the existing design system to ship work efficiently.
Identify gaps revealed by TFL Studio's complexity and propose scalable, reusable patterns that support long-term growth.
At times, you will design graphics that enforce our brand for the product, help content, or for internal or client-facing events (conferences, parties, etc.).
You will collaborate daily with product managers, engineers, and domain experts to deliver a product that users trust for critical workflows. Qualifications:
What we are looking for

• 3+ years of relevant product design experience

A systems thinker who thrives on extending an existing product
Someone who enjoys building onto a foundation--expanding patterns, improving workflows, and scaling complexity without reinventing the product.
Experience designing configuration-heavy or multi-step workflows
You know how to create clarity when many objects, states, and relationships must work together.
Strength in interaction design and content design
You make complex ideas understandable, especially for users with varied technical backgrounds.
Comfort working on a product still evolving
You can design within ambiguity, propose structure where it's missing, and iterate responsibly.
Design system fluency
You can apply patterns consistently and contribute improvements that work across multiple products.
Collaborative working style
Skilled at partnering with PM, engineering, another designer, and SMEs to refine scope and ship high-quality product experiences.
Tooling and process familiarity
Strong Figma proficiency, experience working in iterative development cycles, and enough technical understanding to collaborate effectively with engineers.
This role is not for a UI-only designer. We need someone who understands the problem space, enjoys shaping complex systems, and is motivated by improving and expanding a product that users depend on for critical tasks
