Job Summary

We are seeking a Software Engineer III with strong Ruby on Rails expertise to join our Social Experience team. In this role, you will own feature development within Rails-based backend services that power PrizePicks’ core platform — including feeds, and profiles. You will own the delivery of complex work end-to-end, begin guiding junior engineers, and contribute to architectural decisions that shape your team’s systems. This is a role for someone who can break down hard problems, deliver high-quality solutions, and start having influence beyond their own code.

What You’ll Do

• Own feature development : Take ownership of features end-to-end — from technical design through delivery — breaking complex projects into well-scoped, deliverable pieces.
• Write high-quality code : Produce Ruby code that is idiomatic, performant, well-tested, and raises the bar for the codebase.
• Contribute to architecture : Participate in team-level architectural decisions around data modeling, service boundaries, API design, and background processing patterns.
• Improve quality proactively : Identify opportunities to improve code quality, performance, reliability, and developer experience — and act on them.
• Guide junior engineers : Provide technical guidance to Software Engineers I and II through thorough code reviews, pairing sessions, and design feedback.
• Collaborate cross-functionally : Work with Product, Design, and QA to validate technical decisions and ensure alignment between product goals and implementation.
• Participate in on-call rotation : Take increasing ownership of incident response, contributing to root cause analysis and systemic improvements.
• Build team knowledge : Document technical decisions, data models, and service patterns to strengthen your team’s shared understanding.

What You Have

Experience:

• 3–5 years of professional software engineering experience, with meaningful time building Ruby on Rails applications
• History of delivering complex features within a software team to drive business outcomes
• Experience breaking down ambiguous requirements into concrete technical plans
• Exposure to large-scale, high-throughput distributed systems — you understand the challenges of building software that serves millions of users in real time

Technical Skills:

• Advanced proficiency in Ruby on Rails — you understand the framework deeply and write clean, idiomatic, production-quality code
• Strong PostgreSQL skills — schema design, query optimization, migrations, and understanding of performance characteristics at scale
• Experience designing and building RESTful APIs within Rails
• Solid testing practices — RSpec or Minitest, unit, integration, and end-to-end testing strategies
• Familiarity with background job processing (Sidekiq or similar)
• Familiarity with containerization (Docker) and orchestration (Kubernetes)
• Understanding of CI/CD pipelines and deployment workflows

Working Style:

• Autonomous — you can take an ambiguous problem and drive it to a well-defined solution
• Comfortable providing and receiving direct technical feedback
• Strong written communicator, especially important in a fully remote environment
• Able to balance deep technical work with collaborative design and planning

What Makes You Stand Out

• Experience using AI-assisted development tools for coding, planning, and scoping work
• Experience with agentic coding tools and AI-augmented development workflows
• Prior experience working in a remote engineering organization
• Experience contributing to social or relationship-driven systems (feeds, follows, reactions, activity streams)
• Experience implementing stat-driven profile features (aggregations, counters, derived metrics) in production systems
• Working knowledge of graph-shaped data modeling concepts (user relationships, fan-out patterns, denormalization tradeoffs)
• Experience supporting experimentation in social surfaces (feature flags, A/B tests, ranking iterations)

Where You’ll Live
