[Hiring] Forward-Deployed ML Engineer @Apheris

Role Description

At Apheris, we power federated data networks in life sciences to address the data bottleneck in training highly performant ML models. Our product addresses this by hosting networks where biopharma organizations collaboratively train higher quality models on their combined data. The Apheris product is a set of drug discovery applications - enriched with the proprietary data of network participants. Our federated computing infrastructure with built-in governance and privacy controls ensure that the data IP and ownership always stays with the data custodians.

As we are doubling down on structural biology use cases as a focus area within our drug discovery work, we are looking for a Senior ML Engineer to drive the technical execution for our structural biology models. This is a hands-on, high-impact role focused on advancing the state of the art in applying foundational models to structural biology problems. You’ll work closely with our leadership team and will serve as the technical authority on ML modelling, architecture, and experimentation in this domain.

If you want to be part of a mission-driven team building cutting-edge AI systems for life sciences – and you know what it takes to move from foundational models to domain-specific impact – this role is for you.

What you will do

• Build and implement ML applications in structural biology, particularly around fine-tuning and extending foundational models like OpenFold, Boltz-2 and ESMFold.
• Design and implement model extensions for specific tasks such as protein complex and binding affinity prediction, including data distillation, benchmarking, and evaluation pipelines.
• Work with our customers and academic partners to define data preprocessing, selection, and benchmarking strategies for novel training tasks involving protein structures, complexes, and multimodal biological data.
• Carry out case-studies associated with the above, providing scientific and technical expertise to our customers. You will be involved in the full project pipeline, from scoping through to results delivery and dissemination.
• Design, build, and maintain scalable machine learning models and the pipelines needed for training, inference, and deployment in production.
• Collaborate cross-functionally to ensure models address real-world drug discovery needs.
• Contribute to publications or open-source contributions where relevant.

What we expect from you

• By month 3: Develop a deep technical understanding of the Apheris product and how it maps to the current Structural Biology use-cases we are working on. Contribute to delivery of at least one customer-driven cofolding project.
• By month 6: Building on the outcomes of the aforementioned project, build a customer-ready package for results analysis. Work with our privacy team to understand potential for model reverse-engineering. Drive adoption of the Apheris-generated models with our customers for real-world drug discovery pipelines.
• By month 12: Take ownership of a customer-driven cofolding model development stream, drive product requirements to build out the next generation of cofolding collaborations.

You should apply if

• You have deep experience building and training contemporary models in production, at scale (e.g. AlphaFold, OpenFold, Boltz) and are familiar with modern MLOps tooling.
• You have experience applying ML to real-world protein structure or drug discovery problems.
• You are comfortable working in a fast-paced startup environment and enjoy on customer-driven projects.
• You understand the technical challenges of structural biology and can design scalable data preprocessing, training, and evaluation workflows.

Nice to have

• You have experience in federated learning, privacy-preserving ML, or privacy-preserving model training.
• You’ve published in ML or biology journals/conferences (e.g., NeurIPS, ICML, Nature Methods, Bioinformatics).

What we offer you

• Industry-competitive compensation, incl. early-stage virtual share options.
• Remote-first working – work where you work best, whether from home or a co-working space near you.
• Great suite of benefits, including a wellbeing budget, mental health benefits, a work-from-home budget, a co-working stipend and a learning and development budget.
• Regular team lunches and social events.
• Generous holiday allowance.
• Quarterly All Hands meet-up at our Berlin HQ or a different European location.
• A fun, diverse team of mission-driven individuals with a drive to see AI and ML used for good.
• Plenty of room to grow personally and professionally and shape your own role.

Logistics

Our interview process is split into three phases:

• Initial Screening: If your application matches our requirements, we invite you to an initial video call to explore the fit. In this 30-45 minutes interview, you will get to know us and the role. The interviewer will be interested in your relevant experiences and skills, as well as answer any question on the company and the role itself that you may have.
• Deep Dive: In this phase, a domain expert from our team will assess your skills and knowledge required for the role by asking you about meaningful experiences or your solutions for specific scenarios in line with the role we are staffing.
• Final Interview: Finally, we invite you for up to three hours of targeted sessions with our founders, talking about our culture and meeting future co-workers on the ground.
