Senior Software Engineer Computation/Optimization

About Pelico

We are creating the factory of the future where disruptions are avoided, processes synchronized and value captured. Our factory operations management platform enables factory teams to be more agile and resilient in a world where supply chain disruptions occur every 16 minutes. Pelico empowers users to identify bottlenecks, avoid problems, and focus on innovation instead of fire-fighting. Since our foundation in 2019, we’ve partnered with industry leaders across aerospace, industrial equipment, and luxury watchmaking, revolutionizing factory operations in over 15 countries. Esteemed clients include Airbus, Safran, Cartier, Daikin, and Eaton.

Our Team

With a dynamic team of over 180 professionals across the US and France, Pelico is a melting pot of top-tier talent from Tech, Data Science, and Manufacturing domains.
Our collaborative environment fosters innovation and excellence, driving us to solve complex challenges and shape the future of manufacturing.

Our work has been recognized by Safran (Digital Transformation Award) and Microsoft (scale-up of the year).

Engineering turns Product ambition into scalable, reliable solutions that empower on-site operational teams .

We design a platform that handles high volumes, concurrent users, and complex workflows , while remaining modular, maintainable, and future-proof.

Your Role’s Mission

You will join Pelico’s algorithm engineering team to help improve the scalability and performance of the systems powering our optimization engine.

As Pelico’s platform processes increasing volumes of industrial data, one of our key challenges is ensuring that our algorithms can scale efficiently across large datasets.

Your work will focus on optimizing heavy calculations, improving algorithm scalability, and enabling efficient data partitioning and parallel processing .

What You Will Do

1. Improve the scalability of Pelico’s algorithm engine

• Refactor and optimize existing algorithms to support larger data volumes

• Design solutions that enable data partitioning and parallel processing

• Improve the efficiency of heavy calculations performed across large industrial datasets

• Design data partitioning schemes while ensuring algorithmic consistency and correctness across partitions

2. Build high-performance backend systems in the JVM ecosystem

• Design and implement backend services using Kotlin and Java within the JVM ecosystem

• Optimize performance, memory usage, and computation efficiency

• Ensure backend systems remain scalable, reliable, and maintainable

3. Work closely with product and algorithm teams

• Collaborate with algorithm engineers and product managers to translate optimization problems into scalable software solutions

• Contribute to technical discussions around system architecture and performance improvements

4. Improve the architecture of Pelico’s algorithm platform

• Contribute to the evolution of the platform to support large-scale industrial data processing

• Identify performance bottlenecks and implement solutions that improve system efficiency

Your Impact

Your work will directly impact Pelico’s ability to scale its algorithm platform as our customers and datasets grow.

By improving the performance and scalability of our calculation engine, you will help industrial teams make faster and better operational decisions across complex factory environments.
