Senior Backend Developer (3-6 Years, Trading systems)

This role is for one of our partner companies, Seed raised $4.3M
Senior Backend Engineer- Golang | Trading Platform
We’re looking for a hands-on Lead Backend Engineer to build the technical foundation of a trading platform as it moves from MVP to full-scale launch.
This is a high-ownership, zero-to-one role for someone who enjoys designing systems from scratch, leading a small engineering team, and shipping production code. You’ll help shape the architecture, engineering practices, and backend required to support real-time market data—and, eventually, live trade execution.
What You’ll Own
Design and build the backend architecture powering our trading platform.
Architect scalable microservices, APIs, and database models for real-time market data and future trade execution.
Develop integrations that support seamless experiences across web and mobile applications.
Own projects end to end—from understanding the problem and defining the approach to deployment, monitoring, and iteration.
Establish technical standards, conduct code reviews, and guide a small engineering team while remaining hands-on.
Introduce tools, patterns, and engineering practices that improve scalability, reliability, and development velocity.
Build toward execution readiness so the platform can securely and reliably support live trading once regulatory approvals are in place.
What We’re Looking For
Experience designing and launching backend systems from the ground up, ideally in an early-stage or high-growth startup.
Previous responsibility as a technical lead or engineering team lead.
Strong hands-on experience across backend engineering, including APIs, data pipelines, integrations, infrastructure, and databases.
Production experience with Golang, or strong backend fundamentals and a demonstrated ability to learn new languages quickly.
Experience building scalable, reliable, and secure distributed systems.
A track record of owning systems after launch, including observability, performance, reliability, and incident response.
Experience in a product-led engineering environment where teams own business and user outcomes.
A proactive, adaptable mindset suited to rapidly changing priorities and zero-to-one execution.
Nice to Have
Experience in trading, broking, fintech, or capital-markets products.
Familiarity with market-data systems, order-management workflows, low-latency architecture, or financial data models.
Understanding of the security, compliance, and regulatory requirements involved in building financial platforms.
Experience preparing systems for high-volume, business-critical transaction processing.
