The Role

We are seeking an exceptionally talented and highly productive Staff Engineer—a leader consistently regarded as a “5x Engineer”—to join our core product development team. This isn’t just a coding role; it’s a mission-critical position for someone who can drive monumental technical change, deliver high-quality features five times faster than their peers, and act as a force multiplier for the entire engineering organization.

The ideal candidate thrives in an extremely agile, fast-paced environment, can context-switch seamlessly across the full stack, and possesses the architectural insight to prevent technical debt before it happens. If you are a prolific builder, a relentless optimizer, and a mentor who can elevate the skill level of those around you, we want to hear from you.

What You’ll Do

Exceptional Technical Delivery

• Prototyping and Delivery: Design, develop, test, and deploy complex, high-performance, and scalable software solutions across the full stack. Consistently deliver features and projects at a pace that is multiple times faster than the team average.
• Architectural Leadership: Take ownership of critical system components, providing key input on architecture, design, and implementation choices to ensure long-term stability, scalability, and maintainability.
• Code Excellence: Write exceptionally clean, well-tested, and documented code. Conduct rigorous code reviews that significantly improve the quality and efficiency of the team’s output.

Extreme Agility and Impact

• Rapid Context Switching: Seamlessly shift between front-end, back-end, infrastructure, and database tasks (full-stack proficiency is a must) to remove roadblocks and accelerate team velocity.
• Technical Problem Solving: Act as the go-to expert for diagnosing and resolving the most complex and ambiguous technical issues and performance bottlenecks in production environments.
• Process Optimization: Proactively identify and automate manual, repetitive, or inefficient processes within the development lifecycle (CI/CD, testing, deployment) to enhance overall team productivity.

Mentorship and Organizational Lift

• Knowledge Transfer: Act as a force multiplier by actively mentoring mid-level and junior engineers, setting a world-class standard for technical execution, quality, and velocity.
• Setting Standards: Help define and champion best practices, design patterns, and engineering standards across the department.
• Strategic Influence: Work closely with Product Management and stakeholders to refine requirements, challenge technical assumptions, and ensure we are building the right things, the right way.

What You’ll Bring

• Experience: 7+ years of professional software development experience, with a proven track record of outsized contribution and impact.
• Technical Depth: Expert proficiency in at least Typescript and Python, and deep experience with modern cloud environments (AWS/Azure/GCP).
• Agile Mindset: Deep working experience in highly agile and fast-iteration environments.
• Systems Thinking: Demonstrated ability to understand complex distributed systems, microservices architecture, and performance optimization at scale.
• Tooling Mastery: Expertise in CI/CD pipelines, containerization, virtualization and modern database technologies.

Preferred that you have: (What makes you a 5x Engineer)

• A portfolio or history of delivering projects from start to full completion or significantly overhauling critical systems single-handedly or as the primary technical lead.
• Experience in rapid-development methodologies.
• Public contributions to open-source software, conference speaking, or significant internal tooling development.

Working conditions

This role is a full-time salaried position. Work hours for this position are flexible and will be performed from a home office.
