[Hiring] Principal Full-Stack Software Developer @Calliere

Role Description

This is a remote position.

We’re looking for a Principal Engineer who wants both technical depth and product impact. This is not a “pure architect” role; you’ll be in the code, shaping systems, and setting the bar for engineering quality.

You’ll own major initiatives end to end:

• Define the problem
• Design the architecture
• Choose the technologies
• Drive the implementation
• Shepherd systems safely into production

You’ll be trusted with high autonomy and expected to turn ambiguous business needs into clear, scalable solutions.

Key Responsibilities

• Lead end-to-end delivery of product and platform initiatives, from early problem framing through deployment and ongoing support.
• Establish technical direction that balances immediate delivery with long-term scalability.
• Design and implement robust systems across both frontend and backend layers.
• Collaborate closely with cross-functional partners while maintaining strong individual ownership.
• Make informed trade-offs between speed, maintainability, and performance.
• Contribute high-quality code and set standards through thoughtful reviews.
• Navigate ambiguous problem spaces and turn incomplete requirements into concrete solutions.
• Introduce pragmatic engineering practices suited for a fast-moving environment.
• Continuously improve system performance, reliability, and security as usage grows.
• Take responsibility for production systems, including monitoring, incident handling, and post-incident analysis.
• Document architectural decisions and technical approaches to support future team growth.
• Provide guidance and mentorship to other engineers as the team expands.
• Evaluate tooling and infrastructure decisions, including build-versus-buy considerations.

Qualifications

• Extensive experience (10+ years) in software development with a strong breadth across frontend and backend systems.
• Demonstrated ability to lead and deliver complex initiatives independently in high-growth or startup environments.
• Deep expertise in JavaScript and TypeScript.
• Strong experience with modern frontend frameworks such as React or equivalent.
• Solid backend experience, particularly with Node.js and Go.
• Strong database knowledge across relational and non-relational systems, including performance optimization.
• Experience building APIs (REST and/or GraphQL) and designing service-oriented architectures.
• Familiarity with major cloud providers and distributed system patterns.
• Hands-on experience with CI/CD, infrastructure automation, and production operations.
• Experience working with containerization and orchestration tools.
• Exposure to event-driven architectures and messaging systems.
• Strong system design skills and an understanding of trade-offs in evolving products.
• Ability to operate effectively with limited guidance and shifting priorities.
• Clear communication skills, especially when bridging technical and business contexts.
• Experience leading migrations, refactors, or platform evolution is a strong asset.

Success Indicators

• You deliver critical systems independently that perform reliably in production.
• Your architectural decisions enable both rapid development and future scalability.
• Engineering output improves due to clarity, ownership, and reduced friction.
• Production environments remain stable, and issues are resolved efficiently when they arise.
• You become a trusted technical authority within the team.
