Senior Software Engineer - AI, Integration & Cloud em Lisboa, Portugal

InnoWave is looking for a dynamic, agile person, good communication skills to complete our team. If you're based in Portugal , this might be the opportunity for you!

Senior Software Engineer

Responsibilities

• Design, build, and maintain backend services and APIs in C#/.NET 8+, and in Go or Python as the stack diversifies.

• Develop orchestration flows across APIs, queues, services, and data sources.

• Containerize services and deploy via Kubernetes and infrastructure-as-code, keeping provider-specific coupling contained and replaceable.

• Help evaluate self-hostable alternatives to managed AWS services, and contribute to cutover and parity validation during any transition.

• Design relational schemas, indexes, and queries across SQL Server and PostgreSQL.

• Contribute to conversion, migration, and self-managed PostgreSQL operations.

• Implement LLM use cases (currently Claude), build MCP servers and secure tool integrations, and create AI agent workflows, including how these operate under tighter data-residency constraints.

• Support production systems: debugging, monitoring, incident response, and reliability work.

• Work with product, architecture, and platform teams, and with the Senior Quality Engineer.

Required Skills

• Degree in Computer Science or in similar areas.

• Senior-level experience building and running backend services and APIs that real users depend on.

• Deep proficiency in C#/.NET (8+).

• Demonstrated ability to become effective in another language, Go and Python being the likely directions.

• Comfortable developing and running services on Linux: shell, container runtimes, and reading logs and metrics outside of CloudWatch.

• Strong SQL and relational data modelling, comfortable with PostgreSQL.

• Containers, and exposure to an orchestration platform such as Kubernetes.

• Practical AWS experience, and an understanding of where managed-service convenience becomes lock-in.

• Routine use of AI coding tools (Claude, GitHub Copilot, or similar), with a clear view of where they help and where they don't.

• Fluent in English - written and spoken (mandatory).

• Availability to work in an Hybrid model in one of our offices.

Preferred Skills

• Working knowledge of JavaScript/Typescript.

• Sustained hands-on work in Go or Python on a system in real use, rather than a side project.

• Deeper Linux and Kubernetes operations: system, service hardening, self-hosted observability, and running clusters rather than only deploying onto them.

• PostgreSQL depth: migration from SQL Server including T-SQL and stored procedure conversion, and self-managed operations rather than RDS/Aurora consumption only.

• Running workloads on-premises or in a private cloud, or taking a service through a platform migration.

• Infrastructure-as-code (Terraform, Pulumi, Ansible, Crossplane), ideally against more than one target rather than AWS resources only.

• Messaging and event infrastructure: Kafka, RabbitMQ, NATS, or similar.

• Integrating LLM APIs into production: familiarity with MCP, tool use, or agent frameworks.

• Telco experience: BSS/OSS, provisioning, billing, or network data.
