Job summary

Hex Technologies Inc. is hiring a senior backend engineer to evolve the execution architecture of its graph-based system that compiles, plans, and runs user notebooks.

You will own performance, scalability, and platform integration, including building compute components and a new internal query language to target connected data warehouses. This is a fully remote role within the US Eastern time zone, with the option to work from our NYC office.

Qualifications

• 10+ years of backend engineering experience with a focus on computation and systems architecture.
• Experience with parallel execution strategies, caching, and remote data warehouse computation.
• Proven track record solving large-scale systems design problems with data complexity.
• Ability to translate vague problems into well-articulated technical solutions and roadmaps.
• Strong communicator; comfortable leading across a remote-first team.
• Proficiency in Python and/or TypeScript; experience with both is a plus.

Responsibilities

• Evolve the execution architecture including building new compute components to speed execution.
• Drive parallel execution strategies and caching to reduce latency.
• Instrument systems to surface performance issues and show where time is spent.
• Collaborate to support platform capabilities, like a query language for connected warehouses.
• Author and review proposals and mentor engineers to implement ambitious designs.
• Roadmap long-term designs with milestones across quarters.

Job description

What you will do:

• Evolve Hex's execution architecture - the graph-based system that compiles, plans, and runs user notebooks - including proposing and building entirely new compute components that support faster, smarter execution

• Drive parallel execution strategies and caching approaches that reduce latency and minimize unnecessary round trips to external data warehouses

• Instrument complex systems to surface and diagnose performance problems to give the team and our customers a much clearer picture of where time is being spent

• Collaborate across engineering and product to support new platform capabilities, such as building an internal query language that compiles to the appropriate dialect for any connected warehouse

• Author and review technical proposals, and mentor engineers to implement ambitious designs effectively

• Propose and roadmap long-term designs with clear milestones across quarters

About You:

• 10+ years of backend engineering experience, with a strong focus on computation, performance, database/storage optimization, and systems architecture

• Experience with parallel execution strategies, caching strategies, and the trade-offs involved in remote data warehouse computation. Strong systems thinker with solid intuitions around storage, database performance, algorithms, and data structures

• A track record of solving difficult, large-scale systems design problems involving significant data and operational complexity - writing code and reviewing code of your teammates

• The ability to move from abstract, vague problems to well-articulated, well-reasoned technical solutions - and to roadmap ambitious designs with clear milestones across quarters

• A strong communicator; comfortable leading technical work and collaborating across a remote-first team

• Python and/or TypeScript required; experience with both is a plus

Nice to have:

• Working knowledge of Kubernetes, Docker and cloud infrastructure

• Some frontend experience - this is a backend-focused role, but a willingness to occasionally wire a feature all the way through is a plus

This role is fully remote anywhere within the US Eastern timezone, with the option to work from our NYC office.

Our stack

Our product is a web-based notebook and app authoring platform. Our frontend is built with Typescript and React, using a combination of Apollo GraphQL and Redux for managing application state and data. On the backend, we also use Typescript to power an Express/Apollo GraphQL server that interacts with Postgres, Redis, and Kubernetes to manage our database and Python kernels. Our backend is tightly integrated with our infrastructure and CI/CD, where we use a combination of Terraform, Helm, and AWS to deploy and maintain our stack.

The salary range for this role is: $221,250 - $348,500
