We are looking for Software Engineers that shares the same values of pragmatism, professionalism and transparency as us to join our team in Brazil. You'd be utilising your expertise with both clients and also internally - helping to shape Codurance, and being involved in coaching and mentoring across the company. We support our clients in many ways and you will have the opportunity to work on a wide range of different internal and client projects. Perhaps you’ll work on a greenfield project for a startup, or helping to build a mission-critical system for a large enterprise client. Perhaps you’ll work as an embedded craftsperson, working within our client's existing development to help them to get better at writing their own software. Or maybe you're more interested in helping to introduce the values of Software Craftsmanship and Extreme Programming practices to an organisation through coaching & mentoring.

• Design, implement, and evolve Kotlin and Spring Boot microservices that power generation, hosting, deployments, billing, and analytics. • Build resilient distributed systems running on GKE, Knative, Flux, Helm, Terraform, and Terragrunt. • Architect and optimize multi-tenant data models on Neon and Postgres, including aspects like tenant isolation, branching strategies, and safe schema migrations. • Implement high-performance features using coroutines, structured concurrency, gRPC and HTTP APIs, SSE and WebSockets, and message queues. • Build user-facing features for the Kineto app builder, including dashboards, analytics, editors, session views, run logs, and the billing UI. • Work across React and TypeScript frontends, integrating with backend APIs, remote configuration, analytics, and credit and billing systems. • Contribute to the component library, UX flows, and developer tooling that enable the creation and management of thousands of apps. • Drive performance tuning across the platform (GC configs, container resources, distributed locks, and caching strategies). • Solve real operational challenges such as scale to zero, cold starts, autoscaling, build farm performance, and queue backpressure. • Build and improve the LLM-based generation pipeline that produces thousands of Node.js, Kotlin, and Spring Boot applications. • Design entropy-safe, cache-friendly templates and generation flows that minimize build times, reduce costs, and improve reliability. • Collaborate on prompt design, safety layers, and deterministic generation for reproducible deployments. • Own major architectural roadmap items, including multi-region deployments, advanced billing, secure tenancy, and preview environments. • Mentor other engineers, review complex changes, and raise the engineering quality in the team. • Collaborate with product, design, and infrastructure teams to define the long-term vision for the platform.

• Develop and maintain backend services for card payment processing using PHP (Symfony) and Golang. • Integrate and support payment service providers (PSPs) and acquirers (Adyen, Checkout.com, JP Morgan Chase, etc.) • Design and implement scalable, event-driven architectures for high-load payment systems • Write clean, testable code with comprehensive unit and functional test coverage • Optimize database queries and data models for OLTP workloads (MySQL, MongoDB) • Collaborate with the team on system design, code reviews, and technical decisions • Ensure system observability and troubleshoot issues using ELK stack • Participate in CI/CD pipeline improvements and deployment processes

• Own backend features end-to-end: scope → design → implement → test → ship → observe • Build production-grade web services and APIs (primarily in PHP with Symfony) • Write efficient SQL (MySQL) and use Doctrine ORM effectively; tune queries and indexes • Improve reliability and performance through thoughtful design, profiling, and instrumentation • Partner with Product and Design to turn requirements into simple, lovable solutions • Raise the bar on engineering standards, tooling, observability, and developer experience • Mentor peers (and be open to being mentored); give and receive clear, actionable feedback
