Job description

## Software Engineer IIIApply: FanThreeSixty Leawood, KS 66211: Full time: Posted 13 Days Ago: REQ-5287**Job Description Summary**Software Engineer III is the technical backbone of a product area — the person who can take an ambiguous problem, from a bug fix to a multi-sprint feature, and own it end-to-end without needing to be told how to break it down.**Job Description****Key Responsibilities:** * Own delivery for a significant slice of F360's product surface: bugs, enhancements, and net-new features alike.* Take on large, ambiguous problems and structure them into a plan others can execute against.* Design, build, and maintain code and data across the F360 stack, with working knowledge of how products, workflows, and edge cases connect across systems.* Turn product requirements into technical specs: partner with product owners on requirements, research, and proofs of concept.* Plan and run projects — set milestones, delegate work, and manage the resources needed to hit them.* Write tests and documentation for every change, and call out gaps in coverage before they become production issues.* Review peers' code and participate in architecture/design discussions with real influence over outcomes.* Diagnose and resolve complex bugs, fixing the root cause rather than just the symptom.* Mentor and unblock less senior engineers as part of daily work, not as a side project.* Own features through production — participate in on-call rotation and take responsibility for incident response on services this role owns.* Identify where technical debt or architecture choices are limiting team velocity, and make the case for addressing it — not just execute assigned work. **Required Skills:** * 5–8 years of software development/engineering experience.* Bachelor's degree or equivalent certification in Computer Science, Information Systems, or Software Engineering (or equivalent experience).* Strong grasp of system design, data structures, and modern development practices.* Hands-on with Java, Python, React, or similar; comfortable with Playwright, Vitest, JUnit, VSCode/IntelliJ.* Experience building and consuming REST and SOAP APIs (sync and async), including caching and fault tolerance.* Comfortable designing relational schemas and working with NoSQL data stores.* Solid understanding of microservices architecture and inter-service communication patterns.* Fluent in Git-based workflows and tools like Jira.* Track record of independently scoping, estimating, and communicating project timelines.* Experience mentoring or coaching other engineers.* Familiarity with observability tooling — logging, metrics, tracing, and alerting (e.g., Datadog-class platforms) — as baseline competency, not just testing.* Secure coding practices and data-privacy awareness (OWASP-level fluency), given F360 handles fan/customer data.* Named fluency in CI/CD pipeline design and cloud-native practices (containers, infrastructure-as-code) — beyond just using a pipeline someone else built.* Comfortable using AI-assisted development tools (e.g., Cursor, Claude, Gemini) as part of the daily workflow — not just aware they exist.### About UsWe're tech veterans, data lovers and value creators who understand the challenges of the sports and entertainment industries.
