Elicit is an AI research assistant that uses language models to help professional researchers and high-stakes decision makers break down hard questions, gather evidence from scientific/academic sources, and reason through uncertainty.
What we're aiming for:
Elicit radically increases the amount of good reasoning in the world.
For experts, Elicit pushes the frontier forward.
For non-experts, Elicit makes good reasoning more accessible. People who don't have the tools, expertise, time, or mental energy to make carefully-reasoned decisions on their own can do so with Elicit.
Elicit is a scalable ML system based on human-understandable task decompositions, with supervision of process, not outcomes. This expands our collective understanding of safe AGI architectures.
Visit our Twitter to learn more about how Elicit is helping researchers and making progress on our mission.
Two main reasons:
Currently, Elicit operates over academic papers and clinical trials. One of your key initial responsibilities will be to build a complete corpus of these documents, available as soon as they're published, combining different data sources and ingestion methods. Once that's done there is a growing list of other document types and sources we'd love to integrate!
One of our main initiatives is to broaden the sorts of tasks you can complete in Elicit. We need a data engineer to figure out the best way to ingest massive amounts of heterogeneous data in such a way as to make it usable by LLMs. We need your help to integrate into our customers' custom data providers to that they can create task-specific workflows over them.
In general, we're looking for someone who can architect and implement robust, scalable solutions to handle our growing data needs while maintaining high performance and data quality.
Data pipeline: Python, Flyte, Spark
Probably less relevant to you, but ICOI:
Backend: Node and Python, event sourcing
Frontend: Next.js, TypeScript, and Tailwind
We like static type checking in Python and TypeScript!
All infrastructure runs in Kubernetes across a couple of clouds
We use GitHub for code reviews and CI
We deploy using the gitops pattern (i.e. deploys are defined and tracked by diffs in our k8s manifests)
Consider the questions:
How would you optimize a Spark job that's processing a large amount of data but running slowly?
What are the differences between RDD, DataFrame, and Dataset in Spark? When would you use each?
How does data partitioning work in distributed systems, and why is it important?
How would you implement a data pipeline to handle regular updates from multiple academic paper sources, ensuring efficient deduplication?
If you have a solid answer for these—without reference to documentation—then we should chat!
We have a lovely office in Oakland, CA; there are people there every day but we don't all work from there all the time. It's important to us to spend time with our teammates, however, so we ask that all Elicians spend about 1 week out of every quarter with teammates.
We wrote up more details on this page.
5+ years of experience as a data engineer: owning make-or-break decisions about how to ingest, manage, and use data
Strong proficiency in Python (5+ years experience)
You have created and owned a data platform at rapidly-growing startups—gathering needs from colleagues, planning an architecture, deploying the infrastructure, and implementing the tooling
Experience with architecting and optimizing large data pipelines, ideally with particular experience with Spark; ideally these are pipelines which directly support user-facing features (rather than internal BI, for example)
Strong SQL skills, including understanding of aggregation functions, window functions, UDFs, self-joins, partitioning, and clustering approaches
Experience with columnar data storage formats like Parquet
Strong opinions, weakly-held about approaches to data quality management
Creative and user-centric problem-solving
You should be excited to play a key role in shipping new features to users—not just building out a data platform!
Experience in developing deduplication processes for large datasets
Hands-on experience with full-text extraction and processing from various document formats (PDF, HTML, XML, etc.)
Familiarity with machine learning concepts and their application in search technologies
Experience with distributed computing frameworks beyond Spark (e.g., Dask, Ray)
Experience in science and academia: familiarity with academic publications, and the ability to accurately model the needs of our users
Hands-on experience with industry standard tools like Airflow, DBT, or Hadoop
Hands-on experience with standard paradigms like data lake, data warehouse, or lakehouse
Building and optimizing our academic research paper pipeline
You'll architect and implement robust, scalable systems to handle data ingestion while maintaining high performance and quality.
You'll work on efficiently deduplicating hundreds of millions of research papers, and calculating embeddings.
Your goal will be to make Elicit the most complete and up-to-date database of scholarly sources.
Expanding the datasets Elicit works over
Our users want Elicit to work over court documents, SEC filings, … your job will be to figure out how to ingest and index a rapidly increasing ontology of documents.
We also want to support less structured documents, spreadsheets, presentations, all the way up to rich media like audio and video.
Larger customers often want for us to integrate private data into Elicit for their organisation to use. We'll look to you to define and build a secure, reliable, fast, and auditable approach to these data connectors.
Data for our ML systems
You'll figure out the best way to preprocess all these data mentioned above to make them useful to models.
We often need datasets for our model fine-tuning. You'll work with our ML engineers and evaluation experts to find, gather, version, and apply these datasets in training runs.
Start building foundational context
Get to know your team, our stack (including Python, Flyte, and Spark), and the product roadmap.
Familiarize yourself with our current data pipeline architecture and identify areas for potential improvement.
Make your first contribution to Elicit
Complete your first Linear issue related to our data pipeline or academic paper processing.
Have a PR merged into our monorepo, demonstrating your understanding of our development workflow.
Gain understanding of our CI/CD pipeline, monitoring, and logging tools specific to our data infrastructure.
You'll complete your first multi-issue project
Tackle a significant data pipeline optimization or enhancement project.
Collaborate with the team to implement improvements in our academic paper processing workflow.
You're actively improving the team
Contribute to regular team meetings and hack days, sharing insights from your data engineering expertise.
Add documentation or diagrams explaining our data pipeline architecture and best practices.
Suggest improvements to our data processing and storage methodologies.
You're flying solo
Independently implement significant enhancements to our data pipeline, improving efficiency and scalability.
Make impactful decisions regarding our data architecture and processing strategies.
You've developed an area of expertise
Become the go-to resource for questions related to our academic paper processing pipeline and data infrastructure.
Lead discussions on optimizing our data storage and retrieval processes for academic literature.
You actively research and improve the product
Propose and scope improvements to make Elicit more comprehensive and up-to-date in terms of scholarly sources.
Identify and implement technical improvements to surpass competitors like Google Scholar in terms of coverage and data quality.
In addition to working on important problems as part of a productive and positive team, we also offer great benefits (with some variation based on location):
Flexible work environment: work from our office in Oakland or remotely with time zone overlap (between GMT and GMT-8), as long as you can travel for in-person offsites
Fully covered health, dental, vision, and life insurance for you, generous coverage for the rest of your family
Flexible vacation policy, with a minimum recommendation of 20 days/year + company holidays
401K with a 6% employer match
A new Mac + $1,000 budget to set up your workstation or home office in your first year, then $500 every year thereafter
$1,000 quarterly AI Experimentation & Learning budget, so you can freely experiment with new AI tools to incorporate into your workflow, take courses, purchase educational resources, or attend AI-focused conferences and events
A team administrative assistant who can help you with personal and work tasks
