Job Title: Senior Scala/Akka Developer (Reactive Architecture, Financial Services) Location: Pune, Maharashtra, India About Us: At FusionPact, we are dedicated to building cutting-edge, high-performance solutions that power critical operations within the financial and core banking sectors. We specialize in leveraging Reactive Architecture principles, with a strong emphasis on Scala and the Akka toolkit, to create systems that are responsive, resilient, elastic, and message-driven. Our mission is to deliver innovative and robust software that transforms how financial institutions operate, ensuring scalability and fault-tolerance in even the most demanding environments. We are a team of passionate engineers who thrive on technical excellence, continuous learning, and pushing the boundaries of what's possible with modern distributed systems. The Opportunity: We are seeking a highly skilled and experienced Senior Scala/Akka Developer to join our growing engineering team in Pune. In this role, you will be instrumental in designing, developing, and maintaining high-performance, fault-tolerant, and distributed applications using the Akka ecosystem. If you are passionate about functional programming, concurrent systems, reactive principles, and building resilient solutions that directly impact the financial industry, we encourage you to apply. What You'll Do: 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. Deep and practical expertise in the Akka ecosystem 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. Experience in the Financial or Core Banking Domain is a significant plus. 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. Bonus Points If You Have: 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. Why Join FusionPact?
