Job Description
Senior Software Engineer delivering complex features in fintech marketplace. Mentoring engineers and improving team practices while owning features end-to-end.
Responsibilities:
- Deliver complex features reliably while raising the technical bar of the team
- Design and implement complex features end-to-end; own subsystems and navigate existing codebases with architectural discernment, using AI tooling as an accelerant while applying your own judgment on correctness, security, and alignment with the system's direction
- Participate in design reviews; propose sound technical designs and identify scalability, performance, and reliability risks before they become incidents
- Scope and estimate accurately; deliver features from requirements through rollout and post-release monitoring; communicate risks early
- Mentor junior and mid-level engineers through code reviews and pairing; provide substantive feedback that raises the quality of code around you
- Drive improvements in team practices — testing patterns, observability, code organization — and push back on shortcuts that create long-term cost
- Explain technical decisions clearly to both technical and non-technical stakeholders; represent engineering in product discussions with a security lens
Requirements:
- Production-grade Ruby on Rails
- PostgreSQL with confidence in data modeling and query performance
- Experience building integrations with external systems — REST/GraphQL APIs, webhooks, or third-party vendor connections
- Familiarity with AWS, CI/CD pipelines, and deployment fundamentals
- Familiarity with AI coding assistants (e.g., Claude, GitHub Copilot); you understand where they help and where they fail — hands-on use is a plus, critical evaluation instinct is required
Benefits:
- Competitive compensation including base salary, bonus, and equity
- Employer-sponsored 401(k) with match
- Comprehensive medical, dental, and vision coverage
- Flexible time off and hybrid work environment
- Opportunity to build and scale a critical function at a high-growth fintech company
