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. ## Description 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., * 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. ## Related Videos - [Navigating the Future of Junior Developers in Tech](https://www.wearedevelopers.com/videos/1280-navigating-the-future-of-junior-developers-in-tech) - [Leveraging Real time data in FSIs](https://www.wearedevelopers.com/videos/806-leveraging-real-time-data-in-fsis) - [How Unit Testing Saved My Career](https://www.wearedevelopers.com/videos/1642-how-unit-testing-saved-my-career) - [Improving quality with Agentic AI with Rovo Dev and Xray](https://www.wearedevelopers.com/videos/2005-improving-quality-with-agentic-ai-with-rovo-dev-and-xray) - [NoSQL Data Modeling for Front-end Developers](https://www.wearedevelopers.com/videos/297-nosql-data-modeling-for-front-end-developers) - [From boy scouting to redrawing the landscape](https://www.wearedevelopers.com/videos/1140-from-boy-scouting-to-redrawing-the-landscape) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers) - [What’s the Difference between a Junior, Mid, and Senior Developer?](https://www.wearedevelopers.com/magazine/238-what-s-the-difference-between-a-junior-mid-and-senior-developer) - [The Best Software Developer Blogs to Read](https://www.wearedevelopers.com/magazine/156-the-best-software-developer-blogs-to-read) - [The Best X (Twitter) Accounts for Developers](https://www.wearedevelopers.com/magazine/294-the-best-x-twitter-accounts-for-developers)
