Department/Project Description

Small Teams; Big Data
We look for individuals who are motivated by complex and challenging work. We want to work with people who share compelling solutions to those challenges, solutions informed by their unique experiences, passions, and expertise. We plan to build a Data Platform on top of AWS Ecosystem to port-over some of EMS Legacy applications. We plan to use Scala to build microservices that will provide self-onboarding functionality to our customer and internal users. We, furthermore, plan to build data pipelines on Spark (Scala) and other open-source technologies with the goal of having robust/scalable and resilient data services. The platform will have several User Interfaces built on top of Angular and Typescript to connect the pipelines and services together and provide a optimized user experience. The application/pipelines and microservices we build will run on top of managed Kubernetes.
We're open-minded about new technologies, we're passionate about what we do, and we make time for everyone to learn and grow as the industry changes. Engineers on the team are approachable and ambitious people who think outside the box and together solve big problems. Are you up for the challenge?
We are looking to build multiple value stream teams composed of Front-End/Back-end Software/Data and Infrastructure engineering. We need people that can work hands-on as engineers solving complex problems and building advance software solutions. We face daily challenges that are both unique and engaging, while processing data at petabyte scale. That is over one trillion data points in multiple different data periods. We have consumer privacy and data security at the forefront of all that we do. Our size also allows us to use cutting edge, open-source technologies to tackle the ever-growing challenges.

On behalf of our client, we are looking for a Senior Backend Engineer (Java, C++, Scala).

About the Project

Apache Spark powers data infrastructure worldwide, but at petabyte scale, performance bottlenecks translate directly into massive infrastructure costs.

The company is building a novel engine designed to dramatically accelerate Spark jobs at their core without requiring data teams to change how they work.

The startup has raised $4.5M in seed funding to build a next-generation data infrastructure optimization engine for the AI era.

Responsibilities:

- Own SQL-acceleration projects end-to-end from planning to implementation and measurable outcomes

- Implement algorithms (targeting a custom DSL) for complex SQL functions within a Scala codebase

- Drive performance optimizations for Big Data processing algorithms primarily in Java but also C++

- Research and develop new greenfield development lying at the intersection of Big Data analytics and compilers

- Implement (in a custom DSL) a major SQL operator (e.g. Window aggregate) or smaller SQL expressions

- Migrate a complex code-generated algorithm in a custom DSL to a C++ equivalent

- Invoke Java code via C++ JNI to provide execution of a SQL function for compatibility reasons

- Implement a variant of repartitioning algorithm optimized for edge-case application configurations

- Refactor existing code generation algorithms to accommodate new improvements of a custom DSL

- Improve GitHub actions workflows to accommodate new build options or new comparative benchmarks

Requirements:

- 5+ years of experience with Java

- 3+ years of experience with C++

- 2+ years of experience with Scala

- Experience working with Big Data processing systems (Apache Spark or similar)

- Strong understanding of SQL processing and data processing algorithms

- Experience working with performance optimization and low-level system improvements

- Upper - Intermediate or higher level of English

Company offers:

- Long-term employment with possibilities for professional growth

- Fully remote work

- Reasonably flexible schedule

- 15 days of paid vacation

- Regular performance reviews
