Design, build, and operate highly scalable, resilient, and secure microservices and data processing systems using idiomatic Golang.   Model complex, long-running tax reporting business logic as durable, stateful workflows using Temporal to ensure correctness and reliability.   Implement and optimize data pipelines consuming financial events from Redpanda, ensuring data quality, timeliness, and integrity.  Collaborate with cross-functional teams of tax analysts, legal experts, and product managers to translate complex and evolving regulatory requirements into robust, maintainable, and verifiable software solutions.  Provide technical leadership and mentorship, driving best practices in distributed system design, API definition with gRPC, code quality, and advanced testing strategies.   Build systems with auditability, traceability, and data lineage as a first-class concern to ensure transparency for our auditors and regulators.   Own the full lifecycle of your services, including automated deployment (CI/CD with tools like Jenkins and Terraform), proactive monitoring, and incident response, following a "you build it, you run it" philosophy.

  Technical Environment:

Backend Services: Microservices written in Golang for performance, simplicity, and concurrency.   API Communication: gRPC with Protocol Buffers (Protobuf) for high-performance, strongly-typed, and versionable service-to-service APIs.   Workflow Orchestration: Temporal for durable execution of long-running, auditable business logic workflows.   Streaming Data: Redpanda as a high-throughput, low-latency, Kafka-compatible streaming platform for all tax-relevant financial events. Infrastructure: Cloud platforms (AWS), containerization (Docker, Kubernetes), and Infrastructure as Code (Terraform). Observability: Modern monitoring and observability tools include Prometheus, Grafana, and Datadog.

  Must-Haves:

5+ years of professional software engineering experience, with a proven track record of shipping and operating complex, large-scale systems in production.   Deep, hands-on expertise in Golang, including a strong command of its concurrency models (goroutines, channels), memory management, and standard library.   Demonstrable experience in designing, building, and reasoning about distributed systems, including a strong understanding of microservices architecture and API design patterns (e.g., REST, gRPC).   Exceptional analytical and problem-solving skills, with the ability to deconstruct complex requirements into clear technical components and excellent communication skills for working in a cross-functional environment. 

Nice-to-Haves:

Hands-on experience with Temporal or similar durable execution systems like Cadence or AWS Step Functions. Experience with Redpanda or Apache Kafka, with a solid understanding of the Kafka protocol.   Production experience with gRPC and Protocol Buffers (Protobuf).   Proficiency with AWS, containerization (Docker, Kubernetes), Infrastructure as Code (Terraform), and CI/CD pipelines (e.g., Jenkins).   Experience with modern observability tools like Prometheus, Grafana, and distributed tracing systems.
