Gamification Senior Software Engineer (Ruby on Rails)

PrizePicks is a daily fantasy sports platform covering major sports leagues and esports titles. The company is seeking a Senior Software Engineer specializing in Ruby on Rails to design, build, and own scalable backend services, lead complex technical delivery, improve system reliability, and mentor engineers.

Responsibilities:

• Design and build backend services: Architect and implement Rails-based services that are performant, scalable, and reliable, supporting high-throughput workloads and complex business logic
• Own technical delivery: Lead the technical design and implementation of complex features end-to-end — from product requirements through deployment and monitoring
• Drive system reliability: Diagnose and resolve performance bottlenecks, optimize database queries, and improve the resilience of backend systems under load
• Define technical direction: Propose and drive architectural decisions for your team’s services, evaluating tradeoffs and communicating recommendations clearly
• Mentor and elevate: Provide hands-on mentorship to Software Engineers I, II, and III on your team and in the organization through code reviews, pairing, and technical guidance
• Improve engineering practices: Define, advocate for, and improve best practices around code quality, testing, observability, and deployment for your team
• Collaborate cross-functionally: Work closely with Product Managers, Designers, QA, and other engineering teams to translate product goals into well-scoped technical solutions
• Participate in on-call rotation: Share responsibility for production incidents, contributing to root cause analysis and long-term reliability improvements

Requirements:

• 5–8 years of professional software engineering experience, with significant time building production Ruby on Rails applications
• Proven track record of owning and delivering complex, multi-component features in a team environment
• Experience designing and operating backend systems that handle significant scale and complexity
• Expert-level Ruby on Rails proficiency — you understand the framework deeply, write idiomatic Ruby, and know when to leverage or work around Rails conventions
• Strong proficiency with PostgreSQL, including schema design, query optimization, and performance tuning at scale
• Solid understanding of API design — RESTful services, serialization strategies, and versioning
• Experience with background job processing (Sidekiq or similar) and asynchronous workflows
• Experience with containerization (Docker) and orchestration (Kubernetes)
• Familiarity with CI/CD pipelines and deployment automation
• Understanding of observability practices — logging, metrics, tracing
• Working knowledge of Go — our backend includes significant Go services, and cross-stack capability is valued at this level
• Comfortable working autonomously with minimal direction on ambiguous problems
• Effective communicator who can articulate technical decisions to both engineers and non-technical stakeholders
• Experience working in a fully remote engineering organization
• Able to context-switch between deep technical work and collaborative planning
• You must be authorized to work for any employer in the U.S. We are unable to sponsor or take over sponsorship of an employment Visa at this time
• Atlanta, GA preferred, Remote
• While we prefer candidates based in Atlanta, we are open to qualified applicants from anywhere in the U.S. and are willing to consider remote candidates. #LI-Remote
• Experience leveraging AI-assisted development tools across the development lifecycle — coding, planning, scoping, and code review
• Experience integrating AI tooling into engineering workflows to accelerate team productivity
