About Initiativ

Traditional exchanges haven't had an upgrade in over twenty years. At Initiativ, we’re a team of experienced traders & brokers that want to build the next generation of exchanges: fully digital, open to all, and easy to use. If you believe trading should be simpler, everyone should access the same price, and that technology can do better than layers of paper-heavy intermediaries, Initiativ is the place for you. We focus on commodities markets, with a first asset that industrial companies are forced to buy every year by governmental policy. It’s a ~€1T market dominated by middlemen, and we’re listing it so buyers get direct, low-cost access with clarity and control.

Join us as a Full Stack Engineer

Are you a full stack engineer who knows how B2B trading systems really work? We’re building a dummy MVP of our trading screens and need someone who can turn our product designs into a secure, testable application wired to the in-house backend. You’ll deliver the first version of a simplified yet professional trading interface (order entry, order book, price feed, portfolio/positions) and integrate it with our services.This is a chance to join early and work directly with the founding team to ship the core user journey for the members already signed up on the exchange.

What You’ll Do

• Build the front-end trading screens from our existing designs
• Implement real-time data for prices, depth, and executions
• Integrate the UI with the back-end being developed
• Encode Payment-versus-Delivery (PvD) and fiducie-based constraints in client flows (UX, statuses, settlement states) and surface audit-ready logs
• Possess knowledge of database management
• Document API contracts, edge cases, and operate a tight feedback loop with Product, Risk/Compliance, and Design

Success looks like a workable MVP that the team can iterate on with client feedbacks.

Must-Have Experience

• 3–5+ years as a full stack engineer in trading/fintech B2B (exchanges, broker platforms, OMS/EMS, or institutional dashboards)
• Production experience with React + TypeScript and Node.js services with PostgreSQL
• Building real-time UIs, handling concurrency and optimistic updates
• Testing culture (Jest/Vitest, Playwright/Cypress) and CI/CD basics (Docker, GitHub Actions)
• Previous fintech experience working with start-ups that have successfully gone to market

Who You Are

• You think in feedback loops and ship incrementally with strong craftsmanship
• You’re comfortable pairing with product and compliance to encode market rules
• You care about performance, correctness, and UX in equal measure.
• You own outcomes: from prototype to a demo-ready MVP

Why Initiativ

You’ll be joining an experienced team from a traditional financial background that want to redesign how industrials and institutional buyers interact with global capital markets.
