Job Description

Welcome to Zesty, a dynamic startup at the forefront of cloud optimization innovation!

Zesty’s Mission

Zesty is a startup company specializing in automated optimization solutions, aiming to help organizations reduce costs and enhance operational efficiency. The company offers a range of products designed for DevOps and FinOps teams responsible for managing cloud usage within organizations.

About the Role

We’re looking for a highly experienced Senior Software Engineer with a strong backend orientation (≈70%) who is excited to take real ownership in a fast-growing product team.

This is a key engineering role within the team. You’ll be expected to dive deep into the product domain, influence technical decisions, and help raise the engineering bar - while also contributing hands-on across the stack, including frontend development in React (~30%).

While backend expertise is essential, we are looking for someone comfortable working end-to-end and capable of taking responsibility over product-facing flows.

What You’ll Do

• Design and build scalable backend services in Python within cloud-native, microservices architecture
• Take ownership of complex features end-to-end - from technical design to production
• Contribute to architectural decisions and help shape engineering standards within the team
• Develop and maintain frontend capabilities in React (~30%) as part of product feature delivery
• Work closely with Product and Design to translate complex cloud optimization logic into intuitive user experiences
• Integrate with major cloud providers (AWS, Azure, GCP)
• Improve system reliability, performance, and maintainability
• Participate in code reviews and contribute to a strong engineering culture

Requirements

• 6+ years of experience in software engineering
• Strong backend experience (Python/ Node.js)
• Experience designing and building scalable distributed systems
• Hands-on experience with React in production environments
• Experience working in cloud environments (AWS, Azure, or GCP)
• Solid understanding of APIs, microservices, and modern system design
• Strong ownership mindset and ability to operate independently within a team

Nice to Have

• Experience building SaaS or DevOps-oriented products
• Experience stepping into technical leadership within a team
