About The Position

At PrizePicks, we are changing the game in daily fantasy sports. We are a passionate team of innovators dedicated to creating a best-in-class experience for our members. Our engineering team builds and scales the platform that powers our explosive growth, from real-time contest engines to the services that handle millions of daily transactions. We are looking for a Senior Software Engineer to join our Social Experience team and help us continue to build the future of fantasy sports.

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

Nice To Haves

  • 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
  • Experience building social or relationship-driven systems (feeds, follows, reactions, activity streams, recommendation engine)
  • Experience designing stat-driven profile systems (aggregations, rollups, derived metrics) at scale
  • Experience building social systems that are designed for rapid experimentation (feature flags, ranking experiments, growth loops)
  • Deep understanding of graph-shaped data modeling and fan-out patterns
  • Demonstrated ability to influence technical direction horizontally across teams to ensure cohesive social experiences

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.

Benefits

  • Company-subsidized medical, dental, & vision plans
  • 401(k) plan with company match
  • Annual bonus
  • Flexible PTO to encourage a healthy work/life balance (2 weeks STRONGLY encouraged!)
  • Generous paid leave programs, including 16-week paid parental leave and disability benefits
  • Workplace flexibility and modern work schedules focused on getting the job done, not hours clocked
  • Company-wide in-person events and team outings
  • Lifestyle enhancement program
  • Company equipment provided (Windows & Mac options)
  • Annual performance reviews with opportunities for growth and career development
