Principal Engineer - Unified API Platform

We are looking for a Principal Engineer to lead the design, architecture, and delivery of a unified API & developer platform that will power all current and future products at scale. This is a hands-on technical leadership role at the intersection of platform engineering, developer experience, and distributed systems.

You will own the full lifecycle of the platform- from API standards and governance to SDK development, microservices architecture, and generative AI-enhanced developer tooling. Your work will directly impact hundreds of engineers and millions of end users.

What You’ll Do:

• Architect and deliver a unified API platform focusing on standardization, governance, and developer experience
• Design high-performing, distributed API infrastructure with high availability, observability, and operability
• Lead development of client SDKs with intuitive interfaces for data binding and UI component integration
• Drive innovation using generative AI to automate and enhance API and UI component development
• Collaborate with product managers and cross-functional teams to balance rapid delivery with technical quality
• Mentor senior engineers and shape inclusive team culture built on best practices and ownership
• Own CI/CD pipelines, system performance, and end-to-end reliability.

What We’re Looking For:

• 10+ years of experience in API architecture, design, and development
• Deep expertise in API standards: OpenAPI 3.0, REST, gRPC, Protobuf, JSON
• Experience building SDKs and designing developer-facing APIs
• Proficiency in Go, Java, C++, Rust, or JavaScript (Go/Java preferred)
• Strong background in microservices, message brokers, queues, and pub/sub systems
• Hands-on experience with Kubernetes, Docker, and cloud platforms (AWS, GCP)
• Strong leadership and mentoring skills with track record of cross-functional collaboration
• Excellent English communication skills (B2+)

Nice to Have:

• Experience with generative AI tools in an engineering workflow
• Background in developer platform products (API portals, CLI tools, developer consoles)
• Contributions to open-source API tooling or infrastructure projects

Why Join?

• Work with a globally distributed team on products used by millions
• Remote-first culture with strong engineering leadership
• Competitive compensation based on your skills and experience
• 24 days of annual paid vacation and 5 paid sick days
• Long-term employment opportunity
