Responsibilities

The Engine team develops and maintains core components of the Workato Recipe runtime. Scope includes recipe execution, DSL, event pulling, webhook processing, and job execution. The team owns trigger and event infrastructure that defines how integrations start and react to external events. Current focus: modernization of a high-throughput platform to improve reliability, scalability, and long-term evolvability. Work is platform-oriented and directly impacts runtime performance and system correctness.

In this role, you will also be responsible to:

• Design and implement distributed backend systems in Go with deep consideration of performance and memory behavior.

• Work on runtime-level components operating under high concurrency and throughput.

• Apply in-depth knowledge of Go internals (scheduler, memory model, garbage collection behavior) to improve system efficiency.

• Design and optimize concurrent workflows using goroutines, channels, synchronization primitives, and context propagation.

• Analyze and optimize slice usage, memory allocations, and data structures for performance-critical paths.

• Improve execution engine for custom third-party code (isolation, performance, feature extensions).

• Modernize runtime components with focus on modularity, structured architecture, and observability.

• Improve trigger configuration and execution across webhooks and polling mechanisms.

• Integrate and optimize data storage solutions (Postgres, S3, DynamoDB, Kafka, ClickHouse).

• Identify bottlenecks, race conditions, deadlocks, and performance degradation in distributed systems.

• Own initiatives end-to-end, from design to rollout and production support.

• Conduct code reviews with emphasis on correctness, concurrency safety, and performance characteristics.

Requirements

Qualifications / Experience / Technical Skills

• Strong experience in building scalable distributed backend applications (7+ years).

• Great understanding of all building blocks of large web applications: databases, load balancers, application servers, message brokers, caching, monitoring, etc.

• Good understanding of network protocols and stacks.

• Good understanding of DB technologies: classic databases and modern no-SQL.

• Knowledge of basic data structures and algorithms and how they are used is a must.

• BS/MS degree in Computer Science, Engineering or a related subject, 7+ years of industry experience.

• Readiness to work remotely with teams distributed across the world and timezones.

Nice to Haves

• Background in network programming.

• Background in application, data security.

• Deep knowledge of physical DB design.

• Experience of working with Docker and other isolation technologies.

• Experience of working with public cloud infrastructure providers(AWS/Azure/Google Cloud).

• Experience in related fields (DevOps, ML, DBA, Enterprise applications, etc).

• Experience in building/deploying data processing pipelines is a plus.

• Experience of working with third-party REST APIs at scale (request throttling, batch processing etc).
