Description
T3 is an award-winning AI implementation partner for high-risk industries.
We support the adoption of trustworthy AI across the entire lifecycle. We design and engineer bespoke AI controls, conduct adversarial red teaming on models and AI systems, and implement end-to-end AI governance operating models, aligned to standards we helped write such as the EU AI Act, ISO/IEC 42001 and NIST AI RMF.
About the Role
We are building a new tool: a platform connecting AI safety, security and governance talent with organisations that need them, alongside a flow for organisations to request AI safety evaluations from T3. Figma designs and user flows are complete and approved.
We need an experienced full-stack developer to implement those designs as a working, production-ready product: front end, back end and a simple database.
Engagement terms
Estimated three weeks from kick-off. We will agree the final timeline with the selected developer.
We expect to agree a fixed fee for the whole project upfront. Please still quote your day rate so we can assess value.
Technical approach
Our current website runs on WordPress. We are open on how the new tool is built: a headless or custom stack (React / Next.js), WordPress with appropriate plugins, Webflow, or another approach you can justify. What matters is that it is genuinely functional, maintainable by others after handover, and not fragile. Tell us what you would use and why, including hosting and database.
Screens in scope
Approximately 8 to 10 designed screens, all responsive:
Landing / home
Job listings index, with filter sidebar, search and sort
Job detail page
Candidate profile / metadata view
Application dashboard ("Your Candidates") for organisations reviewing applicants
Organisation dashboard / ops console, table-driven with status states
Request an AI Safety Evaluation: long multi-section form with conditional fields
Requirements
Strong full-stack web development experience
Backend and database development
Authentication, role-based access and user account functionality
Dynamic profile and listing pages
Search, filtering and sorting
Responsive implementation across desktop and mobile
Proven accuracy converting Figma designs into production interfaces
Clean, scalable, maintainable code
Git / version control
Strong attention to detail
Depending on your proposed approach, either React / Next.js and TypeScript, or demonstrable experience building genuinely database-driven applications on WordPress or Webflow.
Preferred experience
Two-sided marketplaces or job boards. Multi-role dashboards. Searchable directories. Multi-step forms with conditional logic. Database-driven applications.

Hello Sara,
Thanks for sharing this really interesting project. Before I can put together an accurate fixed fee and timeline, a few things would help:
1. Can you confirm the exact number and full list of screens from the Figma, including any login/signup, empty states, and error states not obvious from the main flows?
2. How many distinct user roles are there (candidates, organisations, T3 staff/admin), and are there sub-roles within any of these?
3. For job listing search and filtering, is a standard database query enough, or do you need fuzzy/full-text search? This has a real impact on cost and build time.
4. Is there any payment or subscription logic anywhere in the platform (job posting fees, paid evaluations, tiered access), now or planned for a near-future phase?
5. Is the three-week estimate a hard deadline, or does it flex once scope is fully confirmed? Does it include QA time?
Happy to send a fuller technical questionnaire once these are confirmed, but these five would let me give you a realistic number rather than a guess. -

Can I get view access to the Figma file, to confirm scope before finalizing the fixed fee?
Roughly how many conditional branches in the evaluation form?
Do candidates and organisations need in-app messaging, or is it dashboard/status-only?
Any existing data to migrate, or is this a clean build? -

Hi Sara,
Before kick-off, I would mainly want to confirm the user roles/permissions, whether organisations self-register or are approved by T3, and what should happen to an AI Safety Evaluation request after submission.
Happy to review the Figma and technical requirements with you before finalising the build plan.
Kind regards. -

-/ Could you please share the complete Figma designs and approved user flows so I can review not only the screens but all interactions, states, and expected functionality?
-/ For the talent marketplace, can candidates create, edit, and publish their own profiles, or will profiles be managed by T3?
-/ Can organisations create their own job listings, and should jobs have draft, published, closed, or approval states?
-/ Will candidates apply directly through the platform, and should applications support CV/document uploads, screening questions, cover letters, or external application links?
