About The Position

As a Senior Software Engineer on the Tax Platform Engineering team, you will architect, build, and scale the mission-critical systems that ensure accuracy, verifiability, and compliance for our global tax obligations. You will be responsible for engineering the durable systems of record that serve as the definitive source of truth for our financial operations, directly mitigating financial risk and ensuring auditable adherence to complex financial laws in a high-volume, regulated environment.

Requirements

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.

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.
