We're an early-stage startup building a three-sided marketplace in the home-improvement space that connects consumers, retailers, and service providers in a single transaction. Users configure and price an order, choose a service provider, and pay once; funds are held and then split between the parties when the work is approved. We have a complete working prototype and detailed technical specs ready to share under NDA. We're not looking for someone to design the product — we need a strong engineer to build a well-defined system into a production application. What we need built Backend + database: PostgreSQL, a clean API, multi-role authentication and access control, and server-side business/pricing logic. Consumer web app: a multi-step configuration and checkout flow. Two role-based dashboards (web + mobile-first) for the supply side, including scheduling, status tracking, and photo uploads. Marketplace payments (critical): Stripe Connect — hold customer funds, then split into a platform fee and multiple party payouts on approval. Integrations: SMS, transactional email, mapping/geolocation, and file storage. Tech stack Next.js (React) + TypeScript · PostgreSQL · Supabase or AWS · Stripe Connect · React Native / Expo for mobile · Vercel or AWS Amplify · GitHub. Must-have qualifications Shipped at least one real two- or three-sided marketplace (please link it) Stripe Connect — multi-party payments, held funds, split payouts (not just basic Stripe checkout) Strong PostgreSQL + API + multi-role auth / access control Next.js / React / TypeScript Comfortable building from an existing prototype and written spec Clear, proactive communication Nice to have React Native / Expo · Supabase and/or AWS Amplify · Twilio, mapping, and email integrations How we'll work We'll share full details, the prototype, and specs after a signed mutual NDA. Phased delivery, one milestone at a time, starting with a small paid trial task before the full engagement. All work is "work made for hire" with full IP assignment to us (included in the contract). To apply, please include A link to a live marketplace you built (ideally with Stripe Connect). Your answer to this question: "How would you hold a customer's payment and split it between two other parties only after the customer approves the completed work?" A rough MVP timeline and cost estimate, and your availability. Confirmation you're comfortable signing an NDA and an IP-assignment agreement.

Remote, US-Based Only. We’re hiring a pragmatic Full-Stack Product Engineer to own vertical slices of customer products across React/Next.js and Node.js/Fastify, with Prisma and PostgreSQL. A key part of this role is intentional prototyping, paired with close collaboration with Product / Project Managers. We build custom software for real operational environments. That means we often start with fast, focused prototypes to validate workflows, reduce risk, and learn quickly alongside customers and our Product/Project partners. Once the business intent and requirements solidify, we harden it into production-grade software. We are also intentionally leaning into AI as a force multiplier. You’ll use AI agents to accelerate specification, implementation, and testing — not as a shortcut, but as leverage to move faster while maintaining quality. You’ll move fluidly between: - Rapid experimentation - Clear scoping and refinement with Product/Project Managers - Production-quality implementation This is not throwaway prototyping. It’s structured learning that leads to durable systems. WHAT YOU'LL DO: - Own vertical feature slices end-to-end across React/Next.js (TypeScript), Node.js/Fastify APIs, and Postgres via Prisma, partnering closely with Product/Project Managers from concept through delivery - Rapidly prototype workflows and UI flows in collaboration with Product/Project Managers to validate direction with customers - Convert validated prototypes into hardened, production-ready features - Establish and expand automated testing (API + UI) and wire it into CI - Work closely with Product/Project Managers to translate messy user workflows into well-scoped tickets with crisp acceptance criteria - Perform click testing to map real user journeys and identify gaps - Triage, reproduce, fix, and close production issues with clear updates - Design migrations, optimize queries, and steward the data model - Reduce toil via automation (ETL, recurring jobs, tooling improvements) - Use AI agents to accelerate specs, code generation, and testing — with judgment WHAT WE'RE LOOKING FOR: - Experience building full-stack JS/TS products - Solid API design (auth, pagination, error handling, rate limiting) - Strong React/Next.js and Node experience - Comfortable with TypeScript, Fastify, Prisma, Postgres - Experience with automated testing (API + UI) and CI/CD - Comfortable owning tickets and features end-to-end while maintaining tight collaboration with Product/Project Managers - Clear, concise communicator You should enjoy: - Turning ambiguity into clarity - Moving fast early, then tightening things up - Shipping vertical slices that actually work - Improving systems while working inside them - Using AI as leverage — not a crutch PREFERRED EXPERIENCE: - Azure (App Service, Functions, container apps) - Docker basics - ETL pipelines / data migrations - Supporting production systems -Speaking directly with customers when needed - Leapwork, Playwright, Cypress, or equivalent - AI-powered features (RAG, embeddings, evaluation loops) - Observability (metrics, logs, traces) WHY THIS ROLE IS DIFFERENT: You won’t just be handed tickets. You will: - Prototype deliberately - Validate with customers - Productionize what works - Own meaningful slices of real products We’re building custom systems in an AI-accelerated world. The right person will be excited by both the speed of experimentation and the responsibility of making things solid. WHO WE ARE: Valorian builds intelligent systems for industrial operations by integrating data, systems, and AI—designed around how work actually gets done in the field. We combine deep industry business-process expertise with modern technology to deliver clarity across the full execution lifecycle: planned work, its readiness for safe execution, real-time performance in the field, outcomes at completion, and variance between plan and execution so teams can continuously learn and improve. CORE VALUES: - Trustworthy: Committed to building long-term trust by showing up with an authentic high-level of care and taking ownership of outcomes, behaviors, and work product. - Resourceful: Leverages curiosity, ingenuity, creativity, and innovation to accomplish goals; thinks long term, and is focused on sustainable results. - Passionate: Brings infectious energy, passion, and care for what we do and who we work with. - Balanced: Strives for harmony in faith, family, health, fun, and energy. - Connected: Committed to meaningful communication and healthy conflict through listening, transparency, and the courage to receive and give feedback. INTERESTED? If you’re excited about building real products, growing your skills, and helping define what modern development looks like in practice, we’d love to talk. Work is contingent upon successful completion of a background check and pre-engagement drug screening, in accordance with applicable law.

Build polished, performance-conscious React/TypeScript UI for map-driven workflows: 3D entity rendering, real-time status, modal-driven dispatch, complex form ergonomics. Own the UX of multi-step operator flows end-to-end — visual hierarchy, loading/error states, keyboard, accessibility, edge cases. Collaborate on AI-driven features: integrating Claude Agent SDK tool flows, designing prompts and MCP tools, surfacing agent actions and audit logs in the UI. Occasional Python work on FastAPI services when frontend changes need backend hooks. Must-haves 5+ years shipping production React apps with TypeScript. Heavy day-to-day AI tooling — Cursor / Claude / agentic workflows. You move fast with AI, refactor with it, and reason about prompts and tool design (not just autocompletes). Strong UI/UX intuition. You see a Figma or sketch and can ship something that feels right; you push back when the design hurts the user. Works independently and takes initiative — you scope your own work, surface unknowns early, and ship without hand-holding. Detail-oriented — you sweat the loading states, the empty states, the off-by-ones, and the cases everyone else forgot about. Comfort with styled-components, modern hooks, Redux (or equivalent), and careful state design in long-lived single-page apps. Nice-to-haves CesiumJS, Leaflet, Mapbox, or Three.js — anything map / 3D. Python (FastAPI + Postgres) for working across the stack. Experience designing or consuming MCP servers, or building tool-using agents. Real-time / streaming UI experience (SSE, WebSockets, telemetry). A few hard truths before you apply AI is a tool, not a substitute for engineering. We use Cursor and Claude every day, but you still need to understand the code AI produces, debug it when it breaks, and explain trade-offs and decisions when asked. If AI is your only path to a working PR — and you can't defend the PR once it lands — this won't be a fit. You'll inherit complexity. This is a real codebase with history. You'll spend time reading before you write. The bar for "done" is high. "It works on my machine" doesn't ship. We care about edge cases, accessibility, regressions, and the ten things the user might do that you didn't think of. Generic AI-generated cover letters get instant rejection. We can tell. So can the next reviewer.

Prelude Labs is an early-stage startup in Brooklyn rethinking how people create with AI. Today's tools ask you to type a prompt and hope; we think the next creative medium is a conversation with an agent that has taste — and almost none of the interface for that exists yet. We're designing it from scratch: no legacy patterns, no design debt, no status quo to inherit. We're backed by tier-1 investors and moving fast toward our next product milestone. You'd work directly with our Head of Design (14+ years of craft across product and digital experiences) on a contract running through the end of 2026. SCOPE - Interactive high-fidelity prototypes for core product flows (Figma, code, or hybrid — your call) - Motion and micro-interaction design for AI/streaming UI states - Front-end build-out of approved concepts in React + Tailwind - Design system contributions as patterns emerge MUST-HAVE SKILLS - Figma (auto-layout, components, prototyping) - React + Tailwind, solid HTML/CSS/JS - AI-assisted dev tools in your workflow (Cursor, Claude, v0) - A portfolio with work that RUNS — live prototypes, plugins, demos — not just static case studies NICE TO HAVE Three.js / WebGL / shaders, Rive, Spline, Framer, p5.js, motion design. WHY THIS GIG You'd be shaping the foundational surfaces of a product at the frontier of AI and creativity — greenfield work, direct collaboration with the founding team, no legacy design debt, and your prototypes ship. LOGISTICS 20-40 hrs/week through December 2026, extendable, working sessions in our DUMBO Office HOW TO APPLY feel free to include in your proposal the following: 1. One link to something you built that runs 2. Three sentences on an AI creative tool you use and what's broken about it
