Scala Engineer

About this role

As a Scala Engineer, you will work remotely on an hourly paid basis to review AI-generated Scala code, system designs, and technical explanations, as well as produce high-quality reference implementations and step-by-step reasoning for complex engineering problems. You will assess solutions for correctness, clarity, safety, performance, and adherence to the prompt; identify errors in concurrency, distributed systems behavior, JVM performance, functional correctness, and resource handling; fact-check technical information; write high-quality explanations and model solutions; and rate and compare multiple AI responses.

Scala, Functional Programming, JVM

Responsibilities

• Develop AI Training Content: Create detailed prompts across Scala/JVM topics and write high-quality reference answers to guide AI learning.
• Optimize AI Performance: Evaluate and rank AI responses to improve correctness, safety, performance, and contextual relevance.
• Ensure Model Integrity: Test AI outputs for inaccuracies, unsafe patterns, and bias; validate reliability across real-world use cases.

Qualifications

• Bachelor's degree or higher in Computer Science, Software Engineering, or a closely related technical field.
• 4+ years of professional experience building production systems using Scala (backend services, data platforms, or distributed systems).
• Expert-level proficiency in Scala 2.13+ and/or Scala 3, including strong understanding of the type system, implicits/givens, collections, and functional patterns.
• Strong JVM fundamentals: memory model, garbage collection, profiling, performance tuning, and troubleshooting production issues.
• Deep experience with concurrency and effect systems (e.g., cats-effect, ZIO) and/or actor-based systems (Akka/Pekko).
