About Aqemia

Aqemia is a next-generation pharmatech reinventing drug discovery with quantum-inspired physics and generative AI.

Our mission: design innovative small-molecule drug candidates for dozens of critical diseases, faster and smarter, without relying on experimental data.

Unlike traditional approaches, Aqemia starts drug discovery purely in silico. By combining physics-based models with large language models trained on proprietary data, we identify promising molecules with high accuracy before synthesis.

We've already delivered multiple preclinical successes and secured strategic partnership. Our internal pipeline is growing fast, with several programs in in vivo optimization.

We're a team of 65+ based in Paris and London, we bring together chemists, physicists, engineers, and machine learning experts to push the boundaries of what's possible in early-stage drug discovery.

The Role

As a Senior Software Engineer in the team building our product, you will support the daily activities of scientists (physics, ML, deep learning) who produce predictors and prediction flows.

You'll build the engine that enables large-scale computing and seamless data transformation.

Working closely with scientists and engineers, you'll bring automation, scalability, and reliability to one of the most critical layers of our platform, where predictions turn into decisions.

This role combines backend development, system design, and scientific tooling in a fast-paced and collaborative environment.

What you'll do

• Build and scale the engine powering data management and scientific computation
• Design modular, maintainable, and scalable components in Python using best software engineering practices
• Ensure robustness, observability, and performance of the system
• Collaborate with ML scientists and chemoinformaticians to integrate scientific logic into production-grade software
• Contribute to code reviews, testing, and documentation to maintain high engineering standards
• Take part in architectural discussions and drive continuous platform improvements
• Ensure the product is stable and operational, including supporting production environments

What we're looking for

• 6+ years of experience in backend or scientific software development
• Strong Python programming skills
• Solid understanding of system design, API development, and scalable infrastructure
• Experience with ML or scientific computing pipelines is a plus
• Strong sense of ownership, attention to detail, and ability to collaborate across functions
• Comfortable in a fast-paced, team-oriented environment

Preferred mindset

• You enjoy building robust systems that power real scientific impact
• You balance pragmatism and technical rigor to deliver high-quality results quickly
• You thrive working closely with scientists and turning abstract ideas into real features
• You care about writing clean, maintainable code others can build on
