About OpenYield

OpenYield is building a modern automated marketplace for fixed income trading. Our mission is to evolve the standards of fixed income trading through technology and collaboration.

Founded in response to the rise of algorithmic liquidity in fixed income, OpenYield launched its marketplace in 2024 to help modernize a market long defined by manual workflows, fragmented access, and legacy infrastructure. We combine a startup mentality with a sophisticated, detail-oriented approach, and we are building technology that brings firm, executable pricing, flexible integration, and a more efficient trading experience to the bond market.

We are a small, flat, tech-forward team focused on moving quickly, solving hard problems, and reshaping how bond trading works.

The Role

We are looking for a Senior Full-Stack Developer to help build the user-facing applications and platform workflows behind our fixed income marketplace. This role will focus on developing modern web applications in TypeScript with React and Next.js, while working closely with Rust-based backend services that power trading, market data, and platform operations.

You will contribute across the stack, with strong ownership of the frontend experience, including designing and building components, pages, interaction patterns, and application workflows that make complex trading and data interactions intuitive and reliable. This is a strong fit for an engineer who can translate product requirements into thoughtful user-facing interfaces, exercise strong UI and UX judgment, and deliver robust software backed by REST APIs, WebSockets, and PostgreSQL.

What You’ll Do

• Design and build frontend components, pages, and user workflows in React and Next.js
• Own the structure and implementation of user-facing features, from reusable components to page-level experiences
• Partner with product and leadership to turn complex requirements into clear, usable interfaces
• Develop responsive, performant frontend experiences for trading workflows, market data views, and internal tools
• Integrate frontend applications with Rust-based backend services through REST APIs and WebSocket connections
• Partner with backend engineers to define API contracts, data models, and service interactions
• Work with PostgreSQL-backed application data and help design features that are reliable, scalable, and observable
• Improve application performance, usability, reliability, and operational visibility across the stack
• Help shape frontend patterns, component architecture, and overall application UX
• Debug production issues across client, API, real-time, and data layers, and drive durable fixes

What We’re Looking For

• 5+ years of professional software development experience
• Strong experience designing and building production frontend applications with TypeScript and React
• Experience with Next.js in production environments preferred
• Strong product and UI judgment, with the ability to translate requirements into clear, usable application flows
• Experience designing, consuming, and integrating REST APIs in full-stack applications
• Experience building or working with WebSocket-based real-time application features
• Experience working with PostgreSQL or other relational databases in production systems
• Strong understanding of modern frontend architecture, state management, performance, and debugging
• Experience working across frontend and backend boundaries in a service-based architecture
• Strong proficiency with Git and collaborative software development workflows
• Strong engineering judgment and the ability to work independently in a fast-moving environment
• Familiarity with observability, testing, and deployment practices for production web applications
• Clear communication skills and a pragmatic approach to solving hard technical problems
• Comfort operating in a startup environment with broad ownership

Nice to Have

• Experience with Rust, or interest in working more deeply with Rust-based backend systems
• Experience building real-time, data-rich, or workflow-heavy web applications
• Experience with trading, capital markets, market data, or financial infrastructure
• Knowledge of fixed income markets, electronic trading, or marketplace-style systems

Why OpenYield

• Work on meaningful infrastructure in a large, evolving market
• Join a team that is fast, open, and highly collaborative
• Build with modern technology at the center of the business
• Help shape a platform designed to transform fixed income trading

Benefits include medical, dental, and vision insurance, 401(k), unlimited vacation, hybrid or remote work schedule, and professional development opportunities
