[Hiring] Senior Software Engineer @Process Street

Role Description

We’re looking for a Senior Software Engineer to help architect and evolve Process Street into an AI-native product and engineering organization. This is not a traditional “just ship tickets” role. We’re looking for someone who is deeply comfortable working in multi-session coding environments, leveraging tools like Claude Code, Codex, and other agentic workflows to design, build, and iterate faster than conventional development allows.

You’ll operate at the intersection of:

• Product engineering (React / Scala / APIs)
• AI-assisted development systems
• Internal tooling, agents, and developer workflows

You’ll help us rethink how software is built - from how code is written, to how systems evolve, to how teams collaborate with AI.

What You’ll Do

• Architect and evolve backend systems (Scala / Play / Postgres / AWS)
• Design and deploy scalable APIs and AI-assisted services
• Own feature development from end to end (ideation to production)
• Build frontend features using React, Chakra, Storybook, and modern state tools
• Develop and maintain agent-driven development workflows
• Use tools like Claude Code / Codex to accelerate implementation, debugging, and refactoring across multiple sessions in parallel
• Create internal tooling, prompts, and “engineering systems” that improve velocity and code quality
• Optimize performance across frontend, backend, and AI-assisted pipelines
• Help define best practices for AI-native software development
• Eventually lead a small team (2–3 engineers) and shape how they work with AI

Qualifications

• 7+ years of software engineering experience
• Strong experience with backend systems (Scala, or Java / Ruby / C#)
• Strong experience with JavaScript and React
• Experience building and scaling SaaS products
• Deep familiarity with AI coding tools (Claude Code, Codex, Cursor, etc.)
• Comfort working across multi-session, agent-driven workflows
• Strong intuition for when to rely on AI vs. manual implementation
• Experience designing systems, not just implementing features
• Excellent written communication (async-first culture)

About You

• You live in a timezone between UTC -6 to UTC+2 (North American Central Time through Central European Summer Time).
• You think of coding as a collaboration with AI, not a solo activity.
• You’re a Claude Code / Codex power user - you understand configuration deeply, know how to structure contexts, and can reliably steer long-running coding sessions.
• You’ve experimented with or built:
  • Custom dev workflows using LLMs
  • Internal tools, prompts, and “skills” for engineering
  • Agent-like systems that operate across files, repos, or tasks
• You’re comfortable jumping between:
  • Writing code
  • Designing systems
  • Prompting / guiding AI agents
  • Debugging AI-generated output
• You care about leverage - getting more done with smarter workflows, not just more effort.
• You want agency - PMs provide a problem statement and some guidelines – no tickets, no detailed specs, no high-fidelity solutions, and no estimates.
• You love the process but loathe meetings, bureaucracy, and ceremony.
• You want to have a big impact - we're a small team, and we're still at an early stage.

How We Work

We follow the Shape Up process:

• 6-week cycles: solve problems, not tickets
• 2-week cooldowns: improve systems, tooling, or explore ideas

Tech Stack

• Backend: Scala 3 / Play 3, Postgres, Redis
• Frontend: React, Redux, React Query, Chakra, XState
• Infra: AWS, Docker, CircleCI
• AI Workflow: Claude Code, Codex, agent-based tooling (evolving rapidly)

What Makes This Role Different

This is not just a “use AI to go faster” role. You’ll help define:

• How engineers collaborate with AI
• How codebases are structured for agent interaction
• How workflows evolve when AI is a first-class participant

Bonus Points

• Experience with functional programming
• Experience building internal dev tools or platforms
• Experience designing prompt systems or reusable AI workflows
• Opinions about how coding will change in the next 3–5 years (and the ability to act on them)

Benefits

• No Meeting Fridays!
• Unlimited PTO policy – Most take 3-4 weeks, plus their major holidays, AND a company-wide week off in December.
• Company offsite – We get together as a whole company to celebrate company milestones as well as encourage and sponsor small group meetups.
• Social time – We regularly do coffee chats, game-playing, story-telling, house tours (only if you're comfortable), and more to build connections.
• Generous health insurance for US employees and their families, including dental and vision plans.
• Equity for all full-time roles.
