We don't build for one-off success. We build steerable, reliable and explainable agentic systems. And we build these systems for the scale of data our customers bring to the table. Our goal is to unlock the unknowable unknown for customers all over the world.
We want to build a product that becomes indisposable to our customers and as delightful as your favorite consumer product. We move fast and build first of their kind systems.
What we've built:
  1. A custom multi-agent framework powering everything from deep research capabilities to copiloting interfaces paired with distributed systems infrastructure for long running agentic tasks.
  2. The world's most powerful and scalable LLM inference engine - a distributed, asynchronous DAG orchestrator capable of incorporating live graph mutations, cooperating in tandem with our LLM throughput management capabilities.
  3. Elastically scaling data representation and metadata generation → powering the most effective private data retrieval systems.
  4. Industry leading agents solving problems from buy side company diligence to multi billion dollar M&A.

We value engineers who move fast, hold themselves accountable to quality, and are detail-oriented.
Responsibilities
  1. Own critical system components: Take complex requirements and turn them into robust, scaled solutions that solve real customer needs.
  2. Unlock O(1) universal indexing: Build and iterate on our high-scale document build system that enables constant time latency for indexing any content in the world, regardless of data volume.
  3. Drive performance optimization: Architect and implement performance-tuning solutions to ensure our systems operate efficiently at scale, minimizing latency and maximizing throughput across millions of documents.
  4. Mentor and guide: Provide technical leadership, mentorship, and guidance to junior engineers, fostering a culture of learning and growth.

Who You Are
  • Bachelor's or Master's degree in Computer Science, Data Science, Statistics, or a related field. A strong academic background with coursework in data structures, algorithms, and software development is preferred.
  • 5+ years software development experience at a venture-backed startup or top technology firm, with a focus on backend software engineering.
  • Proficiency in building backend and API systems using technologies such as Python, Java, or Go.
  • Extensive experience with cloud platforms (e.g., AWS)
  • Working experience with one or more of the following: Kafka, ElasticSearch, PostgreSQL, and/or Redis
  • Ability to analyze complex problems, propose innovative solutions, and effectively communicate technical concepts to both technical and non-technical stakeholders.
  • Proven experience in leading software development projects and collaborating with cross-functional teams. Strong interpersonal and communication skills to foster a collaborative and inclusive work environment.
