Job Details

Title: Principal Software Engineer & Team Lead

Start Date: Immediate

Position Type: Contract/ Full-time Employment

Location: Remote across USA

About the Role

We are building an infrastructure management platform from scratch-and we need a Principal Engineer who writes code, not just designs systems. You will build the core control plane in Typescript & Go: reconciliation loops, declarative APIs, state machines, and the primitives that make infrastructure programmable. You will also own the developer-facing frontend in TypeScript and Next.js. This is a hands-on technical leadership role. You will ship production code daily, own critical subsystems end-to-end, and set the technical bar for the team.

Key Responsibilities

As a Principal Software Engineer and team lead, you will:

  • Own architecture and system design for core platform services, ensuring they meet reliability, security, compliance, and performance requirements.
  • Lead end-to-end delivery of critical platform capabilities, from technical discovery and design through implementation, rollout, and ongoing improvements.
  • Drive technical excellence in the codebase, setting standards for code quality, testing, performance, and observability, and ensuring they are adopted across the team.
  • Mentor and grow senior engineers, providing clear technical direction, constructive feedback, and opportunities for ownership.
  • Collaborate with product, platform, and security leaders to translate business needs into technical roadmaps, and make thoughtful trade-offs between speed, safety, and maintainability.
  • Continuously improve platform operability, including deployment strategies, telemetry and alerting, incident response practices, and post-incident learning.
  • Identify and mitigate technical risks, proactively addressing scaling, reliability, and security concerns before they impact customers.

Required Qualifications

  • 10+ years of software engineering experience, with 4+ years in senior/staff/principal roles shipping production systems.
  • Expert-level TypeScript proficiency-you can build complex, type-safe applications and reason deeply about the type system.
  • Expert-level Next.js experience building production full-stack applications with SSR, API routes, and modern React patterns.
  • Strong Go experience for backend services, CLIs, and systems-level tooling.
  • Deep expertise in API design-RESTful APIs, versioning, error handling, and building interfaces developers love to use.
  • Experience building control planes, reconciliation loops, or state machines for infrastructure automation.
  • Strong understanding of distributed systems principles and how to design for eventual consistency and failure.
  • Hands-on experience with cloud platforms (AWS/Google Cloud Platform/Azure) and infrastructure-as-code tools.
  • Proven ability to own and deliver complex systems end-to-end, from design through production operation.
  • Track record of mentoring engineers, setting technical direction, and raising the bar for code quality.
  • Experience building developer tools, SDKs, or CLIs that other engineers depend on.
  • Strong opinions on testing, observability, and building systems that are easy to debug and operate.

Preferred Qualifications

  • Contributions to open-source infrastructure or developer tooling projects.
  • Experience building multi-tenant platforms with tenant isolation and resource management.
  • Deep PostgreSQL experience-schema design, query optimization, and handling high-write workloads.
  • Background with event-driven architectures and messaging systems (Kafka, NATS, etc.).
  • Experience designing secure systems with RBAC, secrets management, and compliance requirements.
  • Performance engineering skills-profiling and optimizing Go and TypeScript applications.
  • Prior experience at infrastructure or developer tools companies.

What We're Looking For

  • You write code that others learn from and have strong opinions on building maintainable systems.
  • You understand how infrastructure works and use that knowledge to build robust platforms.
  • You obsess over API design and developer experience.
  • You reason about distributed systems holistically and design for operability from day one.
  • You raise the bar for engineering quality and mentor engineers to grow.
  • You've shipped complex systems and know what it takes to go from design to production
