KEY RESPONSIBILITIES

• 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.

• Prior experience in FinTech, RegTech, or another highly regulated industry

with familiarity with financial data or compliance systems.
