Experience: 4-10 Years

• Lead the design, development, and deployment of highly scalable and reliable distributed systems using Scala and the Akka ecosystem, adhering to Reactive Architecture principles.
• Implement and optimize Akka-based microservices using Akka HTTP for exposing RESTful APIs and Akka gRPC for high-performance inter-service communication.
• Masterfully leverage Akka Futures for asynchronous and non-blocking operations, ensuring efficient resource utilization.
• Proactively identify, diagnose, and resolve complex issues related to Akka applications, applying advanced Akka troubleshooting strategies.
• Work extensively with Akka Actor Systems, demonstrating an in-depth understanding of actor lifecycles, hierarchies, supervision strategies, and effective message passing patterns.
• Utilize Akka Streams to build powerful, back-pressured data processing pipelines for real-time and batch scenarios.
• Contribute to the entire software development lifecycle, from requirements gathering and architectural design to robust testing, deployment, and ongoing support.
• Collaborate closely with product managers, architects, and other engineers to deliver high-quality, maintainable, and performant solutions.
• Mentor junior developers, conduct code reviews, and champion best practices in Scala, Akka, and Reactive System design.
• Participate actively in architectural discussions and contribute to the evolution of our technical stack.
• What You'll Bring:
• Exceptional proficiency in Scala Basics: Demonstrable expertise in functional programming principles (immutability, pure functions, higher-order functions), pattern matching, algebraic data types, and the Scala type system.

• Akka HTTP: Proven track record in designing, implementing, and consuming highly performant and secure RESTful services.
• Akka gRPC: Experience with gRPC for efficient, contract-first inter-service communication.
• Akka Futures: Advanced understanding and application of asynchronous programming, composable futures, and robust error handling.
• Akka Troubleshooting Strategies: Expert ability to diagnose and resolve complex distributed system issues including dead letters, actor crashes, message delivery semantics, and performance bottlenecks.
• Akka Actor System: Masterful understanding of the actor model, including actor lifecycle management (creation, starting, restarting, stopping), supervision hierarchies, message dispatchers, and effective communication patterns (e.g., ask vs. tell).
• Akka Streams: Strong experience in building and optimizing reactive stream processing pipelines, including understanding of Sources, Sinks, Flows, and the intricacies of backpressure.

• This includes familiarity with concepts such as financial transactions, payment processing, risk management, trading systems, or regulatory compliance.
• Solid understanding of distributed systems concepts (CAP theorem, consistency models, eventual consistency), concurrency, and parallelism.
• Proficiency with testing frameworks (e.g., ScalaTest, Akka Testkit) and test-driven development (TDD).
• Strong command of version control systems (e.g., Git).
• Exceptional problem-solving abilities, a strong analytical mindset, and attention to detail.
• Ability to work independently, take ownership, and thrive in a collaborative, agile team environment.
• Excellent communication skills, both written and verbal, with the ability to articulate complex technical concepts clearly.

• Experience with Akka Cluster and Akka Persistence for building truly fault-tolerant and highly available systems.
• Familiarity with cloud platforms (AWS, Azure, GCP) and deploying Akka applications in a cloud-native environment.
• Knowledge of message brokers (e.g., Kafka, RabbitMQ) and event-driven architectures.
• Experience with containerization technologies (Docker, Kubernetes).
• Proficiency with continuous integration/continuous delivery (CI/CD) pipelines.
• Contributions to open-source projects, particularly in Scala or Akka.

• Impactful Work: Opportunity to work on challenging and mission-critical projects that directly impact the financial industry using cutting-edge Reactive Architecture.
