Golang Engineer

We're seeking a talented Golang Engineer to join our core engineering team focused on our B2B Payment Orchestrator. In this role, you'll design, develop, and optimize backend systems that handle high-volume payment processing, ensuring reliability, security, and performance. If you thrive in a fast-paced environment and have a passion for building robust, scalable microservices, this is your opportunity to make a real impact.

Key Responsibilities

• Architect and implement backend services in Golang for payment orchestration, including routing, reconciliation, and integration with third-party APIs (e.g., Stripe, Plaid, or bank APIs).
• Collaborate with cross-functional teams (product, frontend, DevOps) to define requirements and deliver features that support multi-currency, real-time fraud detection, and compliance with standards like PCI-DSS and GDPR.
• Optimize system performance for high-throughput scenarios, handling millions of transactions per day with low latency.
• Write clean, maintainable code with comprehensive unit/integration tests, and participate in code reviews to uphold best practices.
• Troubleshoot and resolve production issues, implementing monitoring and alerting using tools like Prometheus, Grafana, or ELK Stack.
• Contribute to the evolution of our microservices architecture, leveraging containers (Docker/Kubernetes) and cloud infrastructure (AWS/GCP).
• Stay ahead of industry trends in payments tech, proposing innovative solutions to enhance our orchestrator's capabilities.

Required Qualifications

• 3+ years of professional experience as a backend engineer, with at least 2 years focused on Golang development.
• Strong proficiency in Golang, including concurrency patterns (goroutines, channels), error handling, and standard libraries.
• Experience building scalable APIs and microservices, preferably in fintech, payments, or high-stakes transactional systems.
• Familiarity with databases like PostgreSQL, Redis, or MongoDB, and message queues (e.g., Kafka, RabbitMQ) for event-driven architectures.
• Understanding of security best practices in payments, such as encryption, tokenization, and secure API design.
• Proficiency with version control (Git), CI/CD pipelines, and agile methodologies.
• Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent experience).

Preferred Qualifications

• Experience with B2B payment systems, orchestration tools, or financial integrations (e.g., ISO 20022, SWIFT).
• Knowledge of cloud-native development, serverless architectures, or infrastructure as code (Terraform).
• Contributions to open-source Golang projects or familiarity with frameworks like Gin, Echo, or gRPC.
• Exposure to compliance frameworks in fintech (e.g., SOC 2, KYC/AML processes).
• Strong problem-solving skills with a track record of optimizing systems for scale and reliability.
