Senior Software Engineer

Location: Remote (United States)

Department: 410 - Engineering

The Role

Deliver complex features reliably while raising the technical bar of the team. At this level, your scope extends from individual features to subsystems — you own the outcome, not just the task.

Responsibilities

• 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 systems 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

What Were Looking For

• You own outcomes, not just tasks — accountability motivates you
• You build incrementally and surface risks early; you dont absorb uncertainty silently
• You help people around you grow through reviews, pairing, and direct feedback
• 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

Failure Modes We Screen Against

Strong coder, weak owner — ships code but doesnt own outcomes. Solo expert — hoards knowledge instead of sharing. An overconfident designer — proposes solutions without considering trade-offs.

Interview Process

AI coding assistants are allowed in Rounds 2 and 3. We observe how you use them, not whether you use them.

What You’ll Receive

• 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

The anticipated annual salary range for this role is $175,000–$195,000. Actual compensation and title will be commensurate with experience, qualifications, knowledge, and skills.
