Sr Backend | Golang, Node, TypeScript | Payments

What would you do

• Build and evolve payment services end to end using Go for new services and TypeScript and PostgreSQL to maintain and improve existing systems.

• Design and implement payment gateway integrations supporting transaction flows such as authorization capture cancellation and refunds.

• Build reliable transaction workflows that handle retries timeouts idempotency concurrency and partial failures while preserving transaction integrity.

• Drive technical solutions from discovery to production translating business requirements into maintainable designs identifying risks and dependencies early and owning the outcome.

• Contribute to the evolution of our payment platform helping migrate from legacy systems to a scalable modular architecture while maintaining existing customer operations.

• Ensure production reliability and observability using monitoring logs tracing automated testing and incident analysis to prevent issues and improve system resilience.

• Raise engineering standards through thoughtful code reviews pragmatic architectural decisions testing strategies and continuous improvement of development practices.

• Collaborate with Product and other engineering teams to clarify requirements challenge assumptions communicate trade-offs and deliver solutions aligned with business priorities.

• Share knowledge and provide technical leadership mentoring teammates facilitating technical discussions and helping others make sound engineering decisions.

• Contribute to deployment and operations using AWS Docker Terraform and CI/CD pipelines.
  

Your experience has been shaped by

• Go: strong hands-on experience building production services designing APIs managing concurrency and writing maintainable well-tested code.

• TypeScript and PostgreSQL: experience evolving existing backend systems working with relational data optimizing queries and maintaining transactional integrity.

• Distributed systems and microservices: service boundaries asynchronous communication failure handling retries and consistency across services.

• Software architecture: clean architecture domain-driven design modularity and pragmatic approaches to legacy modernization.

• Reliability engineering: idempotency timeouts observability incident troubleshooting and designing resilient systems.

• Automated testing: unit integration and contract testing with a focus on business behavior and critical transaction paths.

• AWS and infrastructure as code: experience with cloud services Docker Terraform and CI/CD pipelines.

• Technical leadership: mentoring engineers conducting meaningful code reviews facilitating technical discussions and influencing decisions without relying on formal authority.

• Cross-functional collaboration: communicating technical trade-offs clearly aligning with Product and managing dependencies across teams.

• Payment systems or transactional domains: experience with payment gateways billing financial transactions order processing or other business-critical workflows. Direct payment experience is a strong plus.

• AI-assisted development as part of your daily workflow: You are already working with AI agents and assistantsnot as an experiment but as a normal part of your workflow.

• Security in payment systems: PCI-DSS scope and tokenization webhook authentication and responsible handling of sensitive data
  

Your SuperPowers

• You are a strong technical problem-solver: you can navigate complex systems understand root causes and deliver robust solutions without overengineering.

• You think beyond the happy path: you anticipate edge cases failure scenarios and operational risks before they become production incidents.

• You take end-to-end ownership: you follow through from technical discovery and implementation to deployment monitoring and production stability.

• You lead through influence: you help teammates grow challenge ideas constructively and bring people together around sound technical decisions.

• You balance pragmatism with engineering excellence: you know when to move fast when to invest in the architecture and how to explain those trade-offs.

• You communicate with clarity: you make complex technical topics understandable and raise risks dependencies and disagreements early.
