Job Description

We’re Underdog.

The fastest-growing sports gaming company, ever. We’re here to make sports more fun. We pair intuitive user experiences with innovative game designs to build the best experience for sports fans in America.

Since 2020, we’ve launched four of today’s most widely played fantasy games, and built the Underdog Sportsbook entirely in-house with our own tech. We move fast, act with urgency, and create experiences you won’t find anywhere else.

With a $1.2 billion valuation and backing from investors like BlackRock, Spark Capital, SV Angel, Mark Cuban, Kevin Durant, Adam Schefter, and more, we’re just getting started.

At Underdog, we play and win as a team. We take chances and are unafraid to attack hard problems. We face challenges with ambition and optimism. We play for the love of the game.

We’re Underdog. And winning as an Underdog is just more fun.

Join us.

About the role and why it’s unique:

  • Build the backbone of Underdog’s data ecosystem—design and deploy internal APIs and workflows that power seamless communication across our services.
  • Create robust, scalable microservices to serve real-time, high-volume data needs for our internal teams, enabling faster decision-making and better fan experiences.
  • Own greenfield projects that shape the future of our business—architecting backend systems built for scale, resilience, and speed.
  • Partner cross-functionally with engineers, product owners, and data scientists to turn complex challenges into elegant, scalable solutions.
  • Safeguard system reliability by building smart monitoring, alerting, and logging tools that keep our infrastructure healthy and performant.
  • Drive impactful technical initiatives from start to finish in a fast-moving, high-stakes environment where your leadership makes a real difference.
  • Champion engineering excellence by leading code reviews, sharing best practices, and helping level up the team through mentorship and feedback.

Who you are:

  • A Backend Engineer with at least 3 years of experience building microservices heavy backend systems and APIs for internal applications on a cloud environment (e.g. AWS, GCP, Azure)
  • Advanced proficiency with Go
  • Experience building and scaling backend systems and designing enterprise scale APIs for external and internal applications
  • Highly focused on delivering results for internal and external stakeholders in a fast-paced, entrepreneurial environment
  • Excellent communication skills with ability to influence and collaborate with stakeholders
  • Familiarity with containerization and orchestration technologies such as Docker, Kubernetes, or ECS
  • Experience with DevOps practices such as CI/CD pipelines, and infrastructure-as-code tools (e.g. Terraform, CDK)

Even better if you have:

  • Strong interest in sports
  • Prior experience in the sports betting industry


Our target starting base salary range for this position is between $135,000 and $150,000 plus target equity. The starting base salary will depend on a number of factors including the candidate’s skills and experience, among other things.

What we can offer you:

  • Unlimited PTO (we're extremely flexible with the exception of the first few weeks before & into the NFL season)
  • 16 weeks of fully paid parental leave
  • A $500 home office allowance
  • A connected virtual first culture with a highly engaged distributed workforce
  • 5% 401k match, FSA, company paid health, dental, vision plan options for employees and dependents

Safe Remote Job Search Tips

Verify Employer Thoroughly

Research the company's identity thoroughly before applying. Check for a professional website with contacts, active social media, and LinkedIn profiles. Verify details across platforms and look for reviews on Glassdoor or Trustpilot to confirm legitimacy.

Never Pay to Get a Job

Legitimate employers never require payment for applications, training, background checks, or equipment. Always reject upfront payment requests or demands for bank details, even if they claim it's for purchasing necessary work gear on your behalf.

Safeguard Your Personal Information

Protect sensitive data like SSN, bank details, or ID copies. Share this only after accepting a formal, written job offer. Ensure it's submitted via a secure company system or portal, never through insecure channels like standard email attachments.

Scrutinize Communication & Interviews

Watch for communication red flags: poor grammar, generic emails (@gmail), vague details, or undue pressure. Be highly suspicious of interviews held only via text or chat apps; legitimate companies typically use video or phone calls.

Beware of Unrealistic Offers

If an offer's salary or benefits seem unrealistically high for the work involved, be cautious. Research standard pay for similar roles. Offers that appear 'too good to be true' are often scams designed to lure you into providing information or payment.

Insist on a Formal Contract

Always secure and review a formal, written job offer or employment contract before starting work or sharing final personal details. Ensure it clearly defines your role, compensation, key terms, and conditions to avoid misunderstandings or scams.
