Build the toolbox for AI scientists

Accelerating the feedback loop

Rafflesia began with a simple question: given the right tools, could an agent reproduce the conclusions of a structural-biology paper from its raw data? The bottleneck was not the model. The tools did not exist.

Every role below owns a different part of the same loop. We turn scientific work into evals, use failures to discover missing primitives, build those primitives into durable systems, and then raise the bar with harder tasks alongside AI and pharma labs.

  1. 01

    Create evals

    Turn real scientific work into reproducible tasks with objective feedback.

  2. 02

    Watch failures

    Agent breakdowns reveal which tools, data, and interfaces are missing.

  3. 03

    Build infrastructure

    Turn those missing primitives into durable, cloud-native systems.

  4. 04

    Raise the bar

    Use the new toolbox to build harder evals with AI and pharma labs.

Why life science

Biology produces experimental data at enormous scale, but much of its infrastructure was designed around local HPC centers and human-operated software. It needs to be rebuilt for the cloud and for agents.

Structural biology also provides unusually rich feedback: geometry, interactions, stoichiometry, simulations, and measurable positions. The laws of physics constrain the work, making it a powerful environment for evaluation and learning.

The problems range from tasks agents can solve today to questions at the edge of protein engineering and nanoscale design. Each solved problem makes the next one possible.

How we build

Open

Move biology out of the walled garden and contribute to open source wherever we can.

Ship progressively

Build the piece, ship the piece, learn from it, and then build the next one.

Software first

Create the standardized procedures, reproducible datasets, and interfaces around existing science.

Cloud native

Reinvent scientific computing for agents and cloud scale instead of inheriting local HPC assumptions.

Open positions

Software Engineer, Homology

Own Rafflesia Homology, our serverless search engine that runs directly on object storage. You'll make tree-of-life-scale search fast, reproducible, and an order of magnitude cheaper: designing immutable index formats, squeezing every query down to the bytes it truly needs, and benchmarking hard against systems like MMseqs2 and Foldseek. Systems, storage, and search background welcome; the biology is learnable.

Apply for this role

Software Engineer, Ontology

Own the semantic layer that lets agents move across proteins, structures, variants, assays, and papers without losing meaning or provenance. You'll design typed models, reconcile identifiers across messy public and proprietary sources, and expose it all through small, stable, versioned interfaces built for agents. For people who care about precise names, explicit types, and abstractions that don't collapse under real data.

Apply for this role

Software Engineer, Foundry

Own AI Foundry, the typed API that puts open biological models behind one uniform surface: structure prediction, embeddings, protein design, and variant effects. You'll turn a sprawl of research repos and checkpoints into explicit model releases with content-addressed results, idempotent jobs, and provenance that survives a rerun, while keeping GPU inference fast and cheap across external providers. For engineers who like serving infrastructure, distributed systems, and making other people's research code run reliably at scale.

Apply for this role

Research Engineer, Benchmarks & Evals

Turn real structural-biology research into reproducible environments that show what agents can do, where they break, and what we should build next. You'll reproduce papers from raw data, design graders and partial-credit signals for long-horizon work, and turn agent failures into usable training signal. A fit if you like reading papers, rebuilding workflows, and finding exactly where a polished result stops being trustworthy.

Apply for this role

Product Engineer (Full Stack)

Build the surfaces where scientists and agents inspect data, run tools, read eval traces, and turn raw infrastructure into daily research workflows. You'll own features end to end, from data model and API contract to a fast, precise, accessible interface, making complex scientific state legible without hiding provenance or uncertainty. Strong full-stack engineers with real product judgment and a taste for interaction detail.

Apply for this role

Forward Deployed Engineer, Pharma

Embed with pharma and AI labs to turn their hardest research workflows into deployed tools, benchmarks, and evals, then fold every hard-won lesson back into the core platform. You'll scope ambiguous problems into real deployments with clear data contracts, run evaluations with partners, and generalize one-off wins into durable product instead of consulting code. For engineers who thrive in ambiguity and next to demanding technical users.
