Job description

Full Stack Software Engineer - MERN Stack
United States
Boom Entertainment
is redefining the way fans engage with sports through innovative, high-quality sports products. Our flagship app, Boom Sports, delivers a fast, fun, and accessible Daily Fantasy Sports experience that's open to players of all skill levels. To date, players on Boom Sports have won close to $100 million in prizes, and our user base continues to grow as more fans choose Boom as their go-to place to play.
Boom is a small team with high standards. We move fast, operate with urgency, and expect high ownership. You will be trusted to figure things out, spot issues early, and drive solutions without heavy process or close oversight. If you want responsibility and work that has real impact, Boom can be an excellent fit. If you prefer a slower pace, highly defined tasks, or being told exactly what to do each day, Boom may not be the right environment.
Responsibilities:
Own features end-to-end: from design discussions through implementation, testing, and production monitoring.
Work across the full stack: frontend, mobile, server, and data layers.
Optimize for performance, stability, and quality of the end‐user experience.
Participate in roadmapping, stand‐ups, code review, and ongoing discussions about best practices and design patterns.
Develop an appreciation for the gaming vertical and contribute to the design, testing, and evaluation of new products and features.
Qualifications:
5+ years of professional software engineering experience.
2+ years of Production React Native experience.
Experience leveraging AI coding tools to prototype, debug, write tests, and improve developer velocity while maintaining code quality.
Creative problem‐solver with strong critical thinking and troubleshooting skills who learns quickly and takes initiative.
Strong communicator and collaborator who makes the people around them better.
Interest in or experience with the Sports and/or Sports Betting industry.
Preferred Qualifications:
Experience working on B2C products at a small company or startup.
Experience with at‐scale integration of 3rd party APIs.
Experience with microservices architecture and client‐server communication (REST, Server Sent Events, websockets, etc.).
This role is not for you if:
You prefer a steady state job where priorities rarely change.
You want highly detailed instructions before starting work.
You are uncomfortable owning deadlines and accuracy without close oversight.
You do not enjoy improving processes, documentation, and structure where gaps exist.
Our target compensation for this position is between $115,000 and $140,000, depending on experience. Should your compensation expectations fall above this range, we encourage you to still apply as we're growing, and we can further evaluate the level of this position. Compensation is just the beginning, and below you will find more reasons Why you should work here.
If you are excited about this role and confident in your fit, you are welcome, but not required, to reach out to our Director of HR on LinkedIn or email careers@booment.com with a brief note explaining why Boom should hire you for this role.
Why you should work here
Uncapped PTO (please use them!)
Quarterly contests and giveaways featuring prizes and swag boxes
A $300 home office reimbursement
Parental support (paid leave, childcare, and adoption benefits)
401K Match & FSA
A great culture that includes support for learning and development
