Senior Software Platform Engineer

Tendium is the global pioneer in AI-driven public tender management, transforming how companies discover, analyze, and win

government contracts. Our platform turns complex processes into something simple and transparent, empowering businesses to compete

fairly for billions in public sector opportunities. We’ve been building our AI-native platform since 2018, leveraging a vast data

moat, agentic AI, and tens of thousands of hours of R&D. Today, we serve large numbers of customers across Europe and are rapidly

scaling.

Our Platform team has a broad and exciting ownership. As a member of our Platform team you will build foundational services that

all our features need, security and developer experience as well as being in the forefront of AI development. You will make sure

that we have the AI tooling we need to build with both speed and quality, and that our platform is secure and easy to monitor and

work with. This is a role where you will spend time on building our product and internal tools as well as building SRE guidelines

and best practices cross-team. The whole tech organisation consists of approximately 20 engineers split into different teams,

where everyone knows each other.

Infrastructure and platform: Hands-on experience with AWS (or equivalent cloud). Containerization (Docker), Infrastructure as Code

(CDK or Terraform), and CI/CD pipeline design and maintenance (GitHub Actions).

Site reliability and operations: Experience defining and tracking SLOs/SLIs, leading incident response, and writing postmortems.

Comfortable structuring production-grade environments — multi-environment setups, security and access standards — and turning that

knowledge into guidelines other teams can adopt.

Cloud micro services: Hands-on experience building and maintaining micro service architectures using AWS services such as SQS,

Lambda, Fargate/ECS (or close equivalents in another cloud).

API design and development: Hands-on experience designing and maintaining APIs, including REST (OpenAPI) and GraphQL, with a focus

on consistency, versioning, and developer experience.

Observability & Reliability: Setting up and using monitoring/alerting tools (Datadog, Grafana, Aikido). Log aggregation and

distributed tracing (OpenTelemetry, CloudWatch)

Software engineering: Strong proficiency in Python (or similar), including writing robust, testable, and maintainable code;

familiarity with async programming patterns.

Collaboration and communication: You enjoy collaborating both with your nearest team and with other teams. You are comfortable

sharing knowledge and best practices.
