Software Engineer, Full Stack Developer

THE POSITION

Our roster has an opening with your name on it

We’re looking for passionate technologists, strong communicators, and those with a commitment to continuous improvement. The ideal candidate will have the confidence to propose pragmatic solutions to complex problems and be eager to learn from and educate others.

As a Software Engineer within the Risk and Trading Technology team, you’ll collaborate closely with data scientists and traders to design, build, and maintain production‑ready systems and tools that drive Fan Duel’s trading operations and sports modeling. You’ll help develop and support:

• Data ingestion pipelines that capture and process large‑scale, real‑time sports data from multiple external providers.
• Backend APIs that power internal models and tools by exposing accurate, performant, and reliable sports data.
• Web applications used by traders to manage risk, adjust lines, and monitor markets efficiently.
• Integration tooling and infrastructure that allow our modeling and trading systems to operate seamlessly in production environments.

You’ll identify opportunities to improve scalability, performance, and reliability across our services while maintaining close alignment with data science workflows. You’ll be encouraged to think big, move fast, and continuously iterate—balancing rapid experimentation with long‑term maintainability and quality.

In addition to the specific responsibilities outlined above, employees may be required to perform other duties as assigned by the Company. This ensures operational flexibility and allows the Company to meet evolving business needs.

Everyone on our team has a part to play

Your work is consistently of high quality. You solve difficult problems, applying appropriate technologies and best practices. You work with your team to invent, design, and build software that is stable and performant. You are proficient in a broad range of design approaches and know when it is appropriate to use them and when it is not. Your solutions are pragmatic.

You consider the legacy of the code you produce and write code that an Engineer unfamiliar with the system can understand. You limit the use of short‑term workarounds. You do things with the proper level of complexity the first time (or at least minimize incidental complexity). You create flexible software without over‑engineering. You make appropriate trade‑offs, re‑use where possible, and are judicious about introducing dependencies.

You are efficient with resource usage (e.g., system hardware, database, memory/CPU, etc.).

• You own parts of product and technology & strive to become a subject matter expert.
• You write simple and extendable code following standards and best practices. You test your code thoroughly. You help balance customer requirements with the team requirements.
• You help your team evolve by actively participating in the code review process, design discussions, team planning, and support ticket reviews.
• You take on projects and make software enhancements that improve the team software and processes.
• You work to resolve the root cause of complex problems, leaving software better and easier to maintain than when you found it.
• You estimate stories/tasks accurately and deliver them in time. You keep yourself up to date with industry tools, utilities, and open‑source frameworks.
• Most importantly, you are humble, pragmatic, self‑managed, thirsty for knowledge, never satisfied and always challenging the norm. Responsible for the state of the code you both inherit and produce.

• BA/BS degree in Computer Science or related software engineering field, or equivalent practical experience.
• Experience and passion working with web libraries and frameworks, such as React, Typescript, and/or Bootstrap.
• Experience writing distributed, highly scalable, and available backend systems & APIs using at least one higher level language (Python, JS, Java, .NET).
• A fundamental understanding of data structures and algorithms.
• Strong sense of ownership, urgency, and drive.
• Demonstrated abilities driving operational excellence and software best practices.
• Experience with testing concepts, test tools, and integrating…
