О компании и продукте

• The Payments Team builds and operates the core services, shared libraries, and infrastructure behind our payment gateway.
• We process merchant transactions across multiple payment providers, so our work sits on the critical path for money movement, and reliability, correctness, and observability are not optional.
• Our goal is to ship faster, keep the system reliable under transactional load, and raise the engineering bar across the org.

Задачи

• Design, build, and maintain backend services and shared libraries consumed across gateway and integration teams
• Develop scalable, cloud-native microservices, gRPC/REST APIs, and integrations in C# on .NET 9, orchestrated locally with .NET Aspire
• Work across our data and messaging stack: PostgreSQL (EF Core), Redis/Valkey for caching, and Kafka for event-driven, asynchronous transaction flows
• Design resilient, correct message-driven flows using proven microservice patterns — Transactional Outbox/Inbox, exactly-once delivery, idempotent consumers, sagas/process managers for distributed workflows, and event sourcing where it fits
• Define and implement engineering standards, reusable patterns, and building blocks (configuration, observability, logging, test frameworks) adopted across teams
• Improve reliability, performance, observability, testability, and maintainability of payment-critical services
• Strengthen observability across services using OpenTelemetry, Prometheus/Thanos, Loki, and Grafana/Coralogix — including RED metrics, tracing, and health probes
• Collaborate with product and integration teams to understand their needs and deliver effective, well-abstracted technical solutions
• Mentor engineers and drive adoption of modern practices, including AI-assisted development

Требования

• Strong backend development experience with C# and ASP.NET
• Experience building distributed systems, microservices, APIs (REST and gRPC), and shared components
• Understanding of microservice design patterns: Transactional Outbox/Inbox, exactly-once/idempotent message processing, sagas, distributed transactions, retries, and eventual consistency
• Hands-on experience with relational databases (PostgreSQL/EF Core) and key-value/caching stores (Redis)
• Experience with message brokers and event-driven architecture (Kafka or equivalent)
• Experience working with AI coding agents / AI-assisted development tools
• Strong grasp of engineering best practices: integration testing, CI/CD, code quality, observability, and reliability
• Ability to take ownership, drive technical initiatives, and collaborate across multiple engineering teams

Будет плюсом

• Experience in payments, fintech, or other high-reliability transactional domains
• Practical knowledge of Docker and Kubernetes
• exposure to GitOps (ArgoCD) and infrastructure-as-code (Terraform)
• Experience running services on AWS (EKS, RDS, MSK, ElastiCache, SSM/Secrets Manager)
• Familiarity with .NET Aspire and OpenTelemetry-based observability
