HOW YOU’LL MAKE A HUGE IMPACT HERE – AND ON YOUR CAREER
As a Senior Software Developer on the Cash App Squad, you will work with a talented group of engineers to ensure that we deliver quality code on time while helping us to streamline processes and optimize our workflow. This is a unique opportunity for focused engineers with a dedication to the craft and an eagerness to improve teams. You will work to deliver new features, fix bugs, reduce tech debt, help level-up less experienced developers via code reviews and mentoring, and help shape and drive team culture.
What You'll Do
- Get stuff done: Implement new features, improve user experiences, and fix bugs in a mature SaaS application.
- Grow those around you: Review PRs to educate others of best practices, pair program with people who are stuck on a problem, ensure the team is following agreed upon standards.
- Design solutions: As needed, work closely with the Implementations Team to turn customer needs/pain points into actionable work with technical designs.
- Help define and implement future architecture: Help create an architectural roadmap to future proof our app and make that plan come to life.
- Focus on NFRs: Ensure we have the right level of resiliency, logging, monitoring, security, etc.
- Support production: Help debug/diagnose/triage emergency production issues (luckily rare).
What You'll Bring to the Team:
- Education & Experience:
- 5+ years of experience with RoR and Javascript.
- B.S. Computer Science, Mathematics, or related field is prefered but not necessary.
- Familiarity with SaaS applications and the FinTech domain are a plus.
- An insatiable desire to make the team awesome; a drive to identify and seize opportunities for wins both in the code and in how the team works.
- A strong understanding of programming patterns, best practices, long term software maintenance, software architecture, and how to balance best vs. practical.
- Work closely with others to achieve team goals. Understand how to give feedback appropriately. Mentor/coach via pair programming if needed.
- Ensure that the code is appropriately optimized (avoiding n+1 queries, etc.), appropriately structured, appropriately formatted, that technical decisions made are right, that the code is well-tested, and that we aren't introducing technical debt.
- Succeed as a team, fail as a team. Promote a blameless culture. See teammates as equals.
