Software Engineer | Fixed Income Platform | AWS-Native

District Partners is working with a mid-market financial services firm operating across broker-dealer infrastructure and investment management, with a core focus on fixed income markets. The firm has built and operates its own trading, financing, and post-trade platform, supporting structured fixed income products in a regulated environment. The engineering team is lean, highly capable, and focused on building systems that directly support trading, clearing, settlement, and financial reporting with a high degree of accuracy and reliability. This role is best suited for a backend engineer who values ownership, precision, and working on systems where output has direct financial and regulatory impact. The environment rewards strong judgment, accountability, and the ability to operate independently within a collaborative, low-friction team. Candidates with exposure to fixed income products such as mortgage-backed securities (MBS), repo, or similar instruments are strongly preferred.
