Software Engineer - Database Engine

Remote - Serbia

Who We Are

At RelationalAI, we are building the future of intelligent data systems through our cloud-native relational knowledge graph management system—a platform designed for learning, reasoning, and prediction.

We are a remote-first, globally distributed team with colleagues across six continents. From day one, we’ve embraced asynchronous collaboration and flexible schedules, recognizing that innovation doesn’t follow a 9-to-5.

We are committed to an open, transparent, and inclusive workplace. We value the unique backgrounds of every team member and believe in fostering a culture of respect, curiosity, and innovation. We support each other’s growth and success—and take the well-being of our colleagues seriously. We encourage everyone to find a healthy balance that affords them a productive, happy life, wherever they choose to live.

We bring together engineers who love building core infrastructure, obsess over developer experience, and want to make complex systems scalable, observable, and reliable.

**We are considering only candidates located in Serbia. This position is fully remote for candidate living in Serbia**

We are building a Knowledge Graph Coprocessor for Snowflake. The database engine, or the logic engine as we like to call it, allows users to make better decisions by applying the rich business logic of their model to their data. As part of the logic engine team, you will work on our next-generation relational knowledge graph management system, within the following areas:

  • Management of data across the cache hierarchy of cloud object storage, local disk, and memory, while pushing the limits of the ability to retain in-memory performance.
  • Data structures that are backed by cloud storage, versioned, write-optimized, and support our advanced join algorithms.
  • Query evaluation that supports all of our computationally challenging workloads.
  • Incremental compilation of our model logic and view maintenance capabilities.
  • Query optimization and planning.
  • Parallelization and distribution of all these components.
  • Orchestration of provisioning, lifecycle, and bookkeeping of user-facing resources like logic engines, databases, transactions, and individual jobs.

What You Will Do

We are looking for people excited to help design and work on these database management system components.

As a part of the team, you will...

  • Work on novel system designs that enable our unique value proposition.
  • Learn about and contribute to our system implementation and how trade-offs on the language side impact it.
  • Interact with our research network on the frontier of database research.
  • You'll have the opportunity to gain exposure to various parts of the system. Since our team is small, you can contribute to multiple components, allowing for a diverse and enriching experience instead of being limited to just one area.
  • Make our system scale up and out, tackling exciting challenges around concurrency and distribution.
  • Tune code, reduce allocations, and write tight hot loops.
  • Have the option to work on the programming language's internals that underpin our system, contributing changes to the language itself.

What We Look For

  • Up to 3 years of professional experience in system-level code.
  • Enthusiasm for database systems, distributed systems, algorithms, and data structures.
  • Willingness and ability to learn quickly, including a new programming language.
  • Ability to work towards a long-term, multi-year strategic objective, while delivering consistent and progressive results along the way.
  • People who are reliable and find ways to be productive. We are looking for individuals who take ownership and will be responsive, knowing we will provide comprehensive support and mentorship to ensure your success.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
