📋 Description

• Review AI-generated Scala code, system designs, and technical explanations. • Produce high-quality reference implementations and step-by-step reasoning for complex engineering problems. • 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 that demonstrate correct methods. • Rate and compare multiple AI responses based on correctness and reasoning quality. • 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.

🎯 Requirements

• Bachelor’s degree or higher in Computer Science, Software Engineering, or a closely related technical field (or equivalent practical experience). • 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). • Experience designing and operating services in distributed environments: microservices, messaging/streaming, retries, idempotency, backpressure, consistency tradeoffs. • Strong testing practices (ScalaTest, MUnit, property-based testing like ScalaCheck) and comfort with CI/CD workflows. • Comfortable with build tooling and dependency management (sbt, Maven/Gradle interop), and version control best practices. • Minimum C1 English proficiency (written and spoken), with the ability to write clear technical explanations and follow detailed English-language guidelines. • Prior experience with AI data training, annotation, or evaluating AI-generated technical content is a strong plus. • Highly detail-oriented and systematic, with a methodical approach to evaluating reasoning quality and identifying subtle issues in Scala/JVM systems.
