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.

Position Overview -
We're hiring an
Optimization Algorithm Developer
to own the algorithmic core of our cloud cost optimization solutions. You'll design optimization strategies, apply predictive and machine learning methods where they add value, and work with backend and data engineers to embed algorithms into production.

This is a hands-on role for someone who enjoys solving complex cost/performance trade-offs at scale and wants to see their algorithms drive tangible impact for customers.

Your Ownership Will Include

  • Develop and refine optimization algorithms for cloud usage and workload management.
  • Use statistical modeling, predictive techniques, and machine learning to analyze patterns and anticipate future behavior.
  • Deliver practical solutions that provide value early and can evolve into production-grade algorithms.
  • Define data and integration requirements; collaborate with backend engineers to operationalize solutions.
  • Establish clear evaluation methods (backtesting, offline experiments, KPIs) to measure performance.
  • Stay current with cloud economics, Kubernetes scaling practices, and FinOps trends.

Requirements

  • 3+ years in algorithm development, applied data science, or optimization.
  • Strong Python skills (PySpark and pandas a plus).
  • Solid foundations in algorithms, optimization, and statistics.
  • Experience applying ML methods (regression, forecasting, anomaly detection, or similar).
  • Proficiency with SQL and working with large datasets.
  • Ability to turn high-level product ideas into concrete algorithmic designs.
  • Strong communication skills for collaboration with Product and Engineering.

Nice to Have

  • Experience in a product-oriented environment with strong backend collaboration.
  • Experience with cloud cost data (AWS CUR or similar).
  • Familiarity with Kubernetes concepts (HPA, autoscaling, resource management).
  • Knowledge of cloud commitments (Savings Plans, RIs, etc.).
  • Background in forecasting or anomaly detection.
  • Exposure to FinOps practices or cloud financial management.

Why is it exciting being a Zester-
At Zesty, we're a team of driven, forward-thinkers passionate about pushing the boundaries of cloud optimization. Our culture encourages creativity, curiosity, and a willingness to embrace challenges.

We Care About
Diversity & Inclusion - Be yourself We welcome employees from all backgrounds and have created a workplace where everyone can feel empowered.

Transparency - Transparency: We share our success stories, failures, processes, numbers, and everything in between. If you want to know something that wasn't shared with you – just ask

One Team- We genuinely trust each other which enables us to act as one team working together toward the same mission. All team members are equally important

Open Communication & Feedback -When facing challenges, we always look for fresh ideas and ways to overcome them and We embrace constructive feedback that can and should be given to anyone

Ego is out at the door - Ego obscures and disrupts everything: the planning process, the ability to

take good advice, and the ability to accept constructive feedback. We operate with a high degree of humility
