About Us HONK is modernizing parking payments across North America. We help municipalities, universities, and private operators move from physical infrastructure to digital permits, mobile payments, and smarter operator tools. We’re hiring a Senior Software Engineer to build and own systems end-to-end on the platform behind HONK’s growth. You’ll deliver new capabilities, strengthen the foundation underneath them, and keep everything fast as volume climbs.

You’re comfortable debugging across the full stack, and you communicate clearly with product managers, partner teams, and non-technical stakeholders.

AI-native engineering: AI is central to how we build. Claude Code is a daily tool for implementation, testing, refactoring, and investigation, and we expect fluency from day one. You own every line that lands in production, whether you typed it or an agent did.

Ruby on Rails hosted on AWS; React front-end; Design, build, and ship features across Rails APIs, React, and background jobs; Use Claude Code as a core part of your workflow, delegating implementation, tests, refactors, and codebase investigation to agents while directing the work with clear specs.

Contribute to system design and architectural discussions; Lead database design: schema modeling, indexing, safe/online migrations, and archival/partitioning strategies; Drive app infrastructure initiatives such as Rails upgrades, dependency management,



and CI/CD pipeline improvements; Write unit and integration tests with useful coverage, and champion testing best practices across the organization.

troubleshoot production issues with a focus on root-cause analysis and long-term fixes over quick ones.

6+ years of professional software engineering experience with strong proficiency in Ruby on Rails.

- Extensive, hands-on use of agentic coding tools (Claude Code or similar): writing clear context and specs, decomposing tasks, rigorously reviewing generated code, and knowing when not to reach for an agent.
- Strong SQL and relational data modeling skills; Experience building modern front-ends in a major JavaScript framework such as React or Angular.
- Transparent communicator who can frame trade-offs, write concise design notes, and collaborate effectively across functions.
- Familiarity with AWS and modern delivery practices (Docker/ECS, CI/CD, Terraform).
- Demonstrated ability to debug across browser, API, background jobs, and database layers.

Bonus Points

Built internal AI tooling: custom Claude Code commands or skills, MCP servers, agent-friendly repo conventions, or evaluation harnesses for AI-generated code.

Led AI adoption on a team, with measurable results.
