Senior Software Engineer - Mutual Funds

Job Description:

Position Description/Function

Brokerage Record Keeping Technology is modernizing how Mutual Fund orders are captured, processed, and record kept. We are rebuilding legacy systems that handle millions of customer transactions per day and protect the billions of dollars entrusted to Fidelity with cloud-native architecture and modern engineering practices.

We are looking for a Senior Software Engineer who owns their work end-to-end: from understanding requirements to delivering production-ready software that the team can stand behind. At L5, you are expected to work independently within an established technical direction, contribute to how that direction evolves, and begin raising the capability of the engineers around you.

Key Responsibilities

- Design and implement backend services and APIs within established architectural patterns, contributing to those patterns as your experience grows.

- Build and maintain full-stack components with consistent quality across backend, API, and front-end layers.

- Take ownership of features: write the code, own the tests, ship to production, and stand behind what you deploy.

- Contribute to team engineering practices: participate in code reviews, improve test coverage, and flag gaps in pipeline and operational readiness.

- Mentor junior and associate engineers through code reviews, pair work, and direct feedback.

- Apply spec-driven development and AI-assisted tooling as a standard part of how you work.

Required Skills and Experience

- 5-7 years of professional software engineering experience delivering production systems.

- Demonstrated ability to own features or services end-to-end, from design through deployment and operation.

- Experience building production-grade backend services, including RESTful API design and cloud-native deployment.

- Hands-on experience with Java and Spring Boot for backend service development. Experience with contract-first API design is valued.

- Cloud deployment experience with AWS: packaging, deploying, and operating services in a cloud environment.

- Delivery pipeline proficiency: source control, CI/CD, containerization, and automated testing.

- Observability basics: writing logs with appropriate signal, understanding distributed traces, and using dashboards to diagnose production issues.

- Database experience across relational and non-relational systems: writing and tuning queries, understanding indexing, and choosing the right tool for the data pattern.

- Exposure to AI-assisted development tooling and interest in applying it as a standard part of your workflow.

 Preferred

- Experience in financial services or a regulated, high-reliability industry.

- Familiarity with event-driven or streaming architectures (Kafka, SQS, or similar).

 The Value You Deliver

- Production software that meets the quality bar the team has set: tested, observable, and documented.

- Accelerated delivery by taking features off the plate of senior engineers and TLs, end-to-end.

- A higher-quality codebase over time through attentive code review and sustainable engineering practices.

- Junior and associate engineers who grow faster because of working with you.
