Strong Product Design Engineer Profile that combines strong product design with hands-on frontend coding
2
Mandatory (Experience 1): Must have 2+ years in product design, with strong depth in dense, complex product interfaces (tables, forms, permissions, multi-role flows) built for real users
3
Mandatory (Experience 2): Must have strong product / visual design judgment along with the ability to ship production-ready frontend code independently. Not a designer who only vibe-codes, and not an engineer who dabbles in UI.
4
Mandatory (Frontend Tech Skills 1): Must have hands-on frontend engineering (React / HTML / CSS / GitHub), able to work directly in a production codebase and write clean, production-ready code (not bloated AI output needing an engineer to fix)
5
Mandatory (Frontend Tech Skills 2): Must be able to set guardrails and standards so AI tools generate clean, production-ready, accessible code that follows the component system, removing the need for a frontend engineer to review design-team code.
6
Mandatory (Portfolio): Must share a GitHub profile and a link to a real product prototype they designed and coded end-to-end. Must show shipped, interactive product UIs. Landing pages, marketing sites, dummy projects, case studies, and Figma / Behance / Dribbble-only portfolios will not be considered.
7
Mandatory (Communication): Must have excellent English communication and be able to clearly articulate their thought process (works with US stakeholders).
8
Mandatory (Company): B2B SaaS background (dense tables / data); early stage startups where design and engineering were not separate functions will also work
9
Mandatory (Exclusion 1): Must not position as Engineer / Developer / PM in their resume. This is a designer-first profile.
10
Mandatory (Exclusion 2): Must not be from big corporates / MNCs (1000+ employees, e.g. Infosys, Wipro) or IT services companies / agencies.
11
Preferred (Profile): Designer-first, engineer-second, with titles like Product Designer, Design Engineer, Design Builder, or Design Technologist; ideally moved from a design role into design-engineering.
12
Preferred (AI): Experience with AI-native interfaces (streaming output, agentic / human-in-the-loop UX, confidence / uncertainty in UI); AI used structurally in shipping features, not just for copy or assets.
