[Hiring] Senior Golang Full Stack Engineer @Avenga

Role Description

We are looking for a Senior Full-Stack Engineer to help build a FinOps and IT Asset Management platform that brings together cloud, SaaS, and AI usage data. This is a genuinely hands-on role spanning modern React/TypeScript applications, Go-based backend services, and Python connectors that integrate with third-party APIs.

• Build data-dense interfaces for cost and usage insights.
• Create and evolve scalable services.
• Develop reliable integrations with cloud providers, LLM vendors, and SaaS platforms.
• Work with real-world API complexity: OAuth and API-key authentication, credential lifecycle, pagination, rate limits, retries, idempotency, partial failures, and normalization of data into the FOCUS FinOps standard.
• Join a cross-functional product team of engineers, product partners, and ITAM/FinOps stakeholders.
• Follow established connector patterns and platform conventions while continuously improving the reliability, scalability, observability, and developer experience of the product.

Qualifications

• 5+ years of professional software engineering experience, including delivery in a consulting, client-facing, or contract environment.
• Strong, recent hands-on experience building production web applications with React and TypeScript.
• Production backend experience with Go, including at least one year of commercial Go development.
• Production experience with Python, particularly for API integrations, data collection, or backend services.
• Proven experience integrating third-party REST APIs, including OAuth/API-key authentication, pagination, rate limiting, retries, idempotency, error handling, and partial-failure scenarios.
• Strong understanding of REST APIs, microservices, distributed systems, and service-to-service integration patterns.
• Solid SQL and data-modelling experience, including practical work with an ORM such as SQLAlchemy, Django ORM, Hibernate, or equivalent.
• Working knowledge of Docker, Kubernetes, CI/CD, Git, and modern code-review and testing practices.
• Experience working in Agile teams using Jira and Confluence as part of the normal development workflow.
• Confidence using AI-assisted engineering tools while critically reviewing, testing, and validating generated code.
• Strong written and spoken communication skills, a pragmatic problem-solving mindset, and the ability to ramp up quickly in a complex product environment.

Requirements

• FinOps, cloud cost management, cloud billing, usage analytics, or familiarity with the FOCUS standard.
• IT Asset Management or software-licensing domain knowledge; experience with FlexNet Manager Suite is a plus.
• Experience with AWS Cost and Usage Report, Azure Cost Management, GCP billing exports, or comparable cloud billing APIs.
• Familiarity with LLM provider APIs, usage or analytics endpoints, and token- or credit-based billing models.
• Experience with gRPC, Protocol Buffers, Databricks, event-driven architectures, or messaging platforms.
• Strong AWS experience, including deploying and supporting production applications.
• Experience with Kubernetes Jobs, ArgoCD, Helm, GitOps practices, or feature-flag platforms such as Split.io.
• Experience with n8n or similar workflow-automation tools, together with sound judgement about when an automation should become a supported service.
• Hands-on experience with observability, monitoring, distributed tracing, and production reliability practices.
• Experience building internal developer tooling, agent skills, MCP servers, or reusable AI-enabled engineering workflows.
• Previous experience in a SaaS product organisation.

Benefits

• People are at the core of Avenga.
• We provide equal opportunities regardless of race, ethnicity, gender identity, sexual orientation, disability, age, religion, or any other characteristic.
• We are committed to a respectful environment where everyone can be themselves, share their ideas, and feel that they belong.
