Isomorphic Labs is applying frontier AI to help unlock deeper scientific insights, faster breakthroughs, and life-changing medicines with an ambition to solve all disease.

The future is coming. A future enabled and enriched by the incredible power of machine learning. A future in which diseases are curtailed or cured starting with better and faster drug discovery.

Come and be part of an interdisciplinary team driving groundbreaking innovation and play a meaningful role in contributing towards us achieving our ambitious goals, while being a part of an inspiring and collaborative culture. The world we want tomorrow is the one we’re building today. It starts with the culture at this company. It starts with you.

Isomorphic Labs (IsoLabs) was launched in 2021 to advance human health by building on and beyond the Nobel-winning AlphaFold system. Since then, our interdisciplinary team of drug discovery experts and machine learning specialists has built powerful new predictive and generative AI models that accelerate scientific discovery at digital speed.

Our name comes from the belief that there is an underlying symmetry between biology and information science. By harnessing AI’s powerful capabilities, we can use it to model complex biological phenomena to help design novel molecules, anticipate how drugs will perform and develop innovative medicines to treat and cure some of the world’s most devastating diseases.

We have built a world-leading drug design engine comprising AI models that are capable of working across multiple therapeutic areas and drug modalities. We are continually innovating on model architecture and developing cutting-edge capabilities to advance rational drug design.

Every day, and with each new breakthrough, we’re getting closer to the promise of digital biology, and achieving our ambitious mission to one day solve all disease with the help of AI.

This is an exciting opportunity for you to contribute to frontier research at the intersection of AI and drug design.

Working in a highly creative, iterative environment, you will join the model performance and scaling team, where you will partner with scientists and engineers to scale foundational models that will transform the biopharmaceutical world as we know it.

You will draw upon your existing engineering experience whilst learning from those around you, to apply novel techniques and ideas to newly encountered model and systems performance optimizations, as well as machine learning, computational biology and chemistry problems.

• Develop custom GPU kernels maximising utilisation and application performance.
• Help design, implement, and optimize distributed training and inference strategies.
• Implement low-level optimisations to overcome hardware limitations.
• Diagnose and debug performance bottlenecks to optimize latency and throughput, impacting real world drug design programs.
• Design low-precision algorithms balancing high performance with minimal accuracy loss.
• Collaborate with researchers to create efficient training and inference model architectures.

• Significant industry experience and strong working knowledge of HPC and ML systems.
• Good understanding of GPU and other AI accelerator architectures.
• Strong knowledge of data structures and algorithms.
• Experience with deep learning ML frameworks (preferably JAX).

• Knowledge of XLA, Triton, Pallas, CUDA or similar accelerator DSLs / compiler stacks.
• Experience with distributed training and data/model sharding strategies.
• Knowledge of collective communication libraries (e.g. NCCL).
• Experience with optimising ML accuracy using low-precision formats.
• Experience building, deploying and maintaining production systems on GCP.
• Interest in chemistry and biology.

• Thoughtful: curiosity, creativity and care; rigorous and future-making science every day.
• Brave: initiative and integrity; fearless in the face of large challenges.
• Determined: confidence in hypotheses, urgency and agility to deliver results.
• Together: collaboration across fields and meaningful relationships that enable impact.

We are committed to equal employment opportunities regardless of sex, race, religion or belief, ethnic or national origin, disability, age, citizenship, marital, domestic or civil partnership status, sexual orientation, gender identity, pregnancy or related condition (including breastfeeding) or any other basis protected by applicable law. If you have a disability or additional need that requires accommodation, please do not hesitate to let us know.

It’s hugely important for us to share knowledge and build strong relationships with each other, and we find it easier to do this if we spend time together in person. This is why we follow a hybrid model, and would require you to be able to come into the office 3 days a week (currently Tuesday, Wednesday, and one other day depending on which team you’re in). If you have additional needs that would prevent you from following this hybrid approach, we’d be happy to talk through these if you’re selected for an initial screening call.
