Platform Engineer (Frontend, Backend, Cloud or Tooling)

As a Platform Engineer, you help build the architectural foundation that allows Pit to scale from hundreds to thousands and eventually millions of systems. Your work ensures that systems built on the Pit platform remain consistent, reliable, and easy to evolve over time. The platform is the foundation that allows AI\-driven development and large\-scale system delivery to work in practice. **Responsibilities** You are expected to be comfortable working in at least two of the following areas, and willing to collaborate across all four when designing platform capabilities: * **Frontend** : shared UI patterns, templates \& design systems, client architecture * **Backend** : system architecture, APIs, data models, reusable integrations * **Cloud** : infrastructure, deployment systems, runtime environments, observability * **Tooling** : monorepo and customer repository tooling, tests and evals setups, workflow environment, developer CLI Your work would contribute to: * designing and evolving the platform architecture * building and maintaining shared frameworks and internal packages * improving infrastructure, deployment, and system lifecycle tooling * ensuring consistency across customer systems * minimizing introduced complexity relative to value created * enabling safe migrations and large\-scale platform improvements * maintaining thousands of customer applications You do this as part of a team of highly skilled and highly motivated, seasoned engineers. **What Success Looks Like** * systems built on the platform remain predictable and maintainable * platform improvements can be rolled out safely across many systems * engineers can build new systems quickly without reinventing core components **Tech Stack** We build with TypeScript end\-to\-end in several pnpm monorepos, prioritizing type safety, developer experience, and clean architecture. * **Frontend** : React 19, React Router 7, Vite, Tailwind CSS v4, shadcn/Radix UI, TanStack React Query, Zustand, React Hook Form, Zod * **Backend** : Node.js, Hono, tRPC, Drizzle ORM, PostgreSQL * **Coding agents** : Currently Claude Code and Codex * **LLMs** : Multi\-provider support (Anthropic, Cerebras, Gemini, Mistral, OpenAI) * **Infrastructure** : Currently Google Cloud Platform (Cloud Run, Cloud SQL, Cloud Storage, Secret Manager), Pulumi (IaC), Docker, GitHub Actions. We will add support for all major clouds * **Testing** : Vitest, Testing Library, Playwright * **Tooling** : pnpm workspaces, Biome (lint/format), custom CLI for dev workflows, architecture validation system with auto\-generated documentation **Qualifications** **Required (All Candidates)** * 8\+ years of professional software engineering experience spent building production systems, of which 3\+ years in TypeScript/Node.js * Experience designing and maintaining shared abstractions, frameworks, or internal packages used by other engineers * Track record of working in codebases at scale where consistency, maintainability, and migration safety matter * Experience working with coding agents (Claude Code, Codex, Cursor) as part of your development workflow * Clear, direct communication style. You write well and explain technical decisions to non\-technical stakeholders **Area\-specific requirements, at least two required** *Frontend* * Deep experience with React and component architecture * Strong understanding of when to use local state, context or external state management * Fluent across the spectrum of tests (unit, integration, e2e) * At least one of: Experience with design systems OR Highly proficient with animations, micro\-interactions and other eye\-candy that elevates the UI/UX OR Track record of shipping a wide variety of frontend applications *Backend* * Strong experience designing APIs, data models, and system architecture with PostgreSQL or similar relational databases * Proficient in SQL and comfortable reviewing and writing database migrations * Experience designing for failure: retries, idempotency, dead\-letter queues, and knowing when it is safe to retry and when it is not * Track record of building reusable integrations or service abstractions *Cloud* * Hands\-on experience with cloud infrastructure (GCP, AWS, or Azure), containerized deployments, and infrastructure as code * Track record of building deployment pipelines, observability, and runtime environments *Tooling* * Experience building developer tooling, CLIs, or monorepo infrastructure * Track record of improving developer workflows, test infrastructure, or build systems **Preferred** * Experience maintaining or migrating large numbers of applications or services simultaneously * Experience building integrations with external systems (ERPs, data warehouses, third\-party APIs) including keeping local data copies in sync via bulk imports and async event processing * Background in platform teams where your work directly multiplied the productivity of other engineers * Familiarity with our specific stack (React 19, Hono, tRPC, Drizzle, PostgreSQL, Pulumi, Vitest, Playwright) * Experience in enterprise or B2B environments where security, compliance, and auditability matter **Not a Fit If** * You prefer working on a single product rather than building foundations that others build on * You have not worked in a codebase where architectural discipline and consistency were critical * You are intimidated by the idea of maintaining thousands of systems. That is what we are building towards **About Pit** **Where intent becomes reliable systems** Our vision is a world where the friction between an idea and a production\-ready system is zero. Our mission is to help companies run their operations on custom software they can trust. **Our Principles** **1\. Start With the Customer** Everything we build serves someone. We stay close to real users and workflows to understand their constraints and outcomes, testing against reality rather than our own taste. Technical elegance is nice, but without user value it is redundant work. We do not build features to feel productive. We build them because they create clear, durable value for the people using what we make. *The customer is not a stakeholder to satisfy. They are the reason we exist.* **2\. Think Like an Owner** We take extreme ownership of our work and our mistakes. When pressure hits, we don’t point fingers or hide. We flag problems early, make a plan, and focus on the solution. We believe accountability is the fastest way to learn and improve. Speak up. If something is broken, unclear, or heading in the wrong direction, say it directly, early, and to the right person. We hold strong opinions but remain willing to change our minds when presented with better arguments. Silence is not neutrality; it is a choice that lets problems compound. We do not punish people for raising hard things. We expect it. **3\. Set the Standard** Quality compounds, but so does mediocrity. We hold exceptionally high standards in our product, code, design, and hiring. We do what’s right, even when nobody’s watching. We will take shortcuts, but conscious ones. We document them so they don’t become debt nobody owns. *The bar is not what we produce today. It is what we commit to produce every time.* **4\. Build Lego Blocks, Not Artworks** We do not build in silos. We maintain a big\-picture view of the product, the architecture, and the company to ensure our decisions are scalable and durable. We choose the right level of complexity to solve root causes, not surface symptoms. “Good enough and fast” is a legitimate choice, but only when it makes the next thing easier to build, not harder. That is the standard. Everything we ship should compound. Every decision we document should make the company smarter. Our job is not just to solve today’s problem well. It is to leave the platform, the culture, and the codebase better than we found them. **5\. Win Together** No one carries the weight alone. When the load is heavy, we rally beyond role boundaries because we care about each other’s performance and well\-being. High talent density only works if we operate as one unit. Act with good intent. Assume your colleagues are trying their best. Give feedback to help, not to score points. Challenge decisions openly before they are final, then commit fully once they are. We do not play politics. We do not undermine quietly. We trust each other enough to be honest, and we expect the same in return. **6\. Empower People with Technology** Technology is powerful and comes with real societal changes. We don't pretend otherwise and we take that seriously. Every solution we ship should make organizations and the people in them more capable, not just more efficient. We think about where the human goes, not just where the workflow goes. Technology done right lifts the ceiling on what people can focus on.
