Job Description:

We’re looking for a Senior Backend Engineer to help bring this vision to life. You’ll design and build core services, shape APIs, work on data ingestion and orchestration, and contribute to the open-source projects we depend on. You’ll be a key part of a small, startup-mode team inside Aiven, shipping fast, learning from users, and setting the technical foundation for a product that will scale.

Job Responsibility:

Design and implement managed open source services that power the metadata discovery and governance system
Build and extend the Metadata Orchestrator, listening to control-plane events and orchestrating ingestion jobs without messy cron scheduling
Develop ingestion connectors & pipeline and backend logic for indexing and serving metadata
Shape APIs (REST/HTTP) that connect the backend with UI and integrations
Work with identity & policy mapping so Aiven Teams, Projects, and SSO map cleanly into managed service access controls (RBAC/ABAC)
Focus on operability: deployment patterns, monitoring, observability (metrics/logs/traces), and incident response
Collaborate closely with engineers, designers, product, and platform/security teams to deliver end-to-end functionality

Requirements:

Solid experience building backend services for managed services/SaaS
Hands-on coding experience with: Python for backend services, ingestion, and orchestration
REST APIs as a primary interface
JVM (Java / Kotlin) for fixes and improvements in the open-source projects
Knowledge of data storage and indexing systems: relational DBs (PostgreSQL/MySQL), search engines (OpenSearch/Elasticsearch), and event logs (Kafka)
Familiarity with Kubernetes, Terraform/IaC, and cloud networking basics
A security-conscious mindset: you think about threat modeling, access controls, and auditability
Pragmatic problem-solving: you enjoy building clean systems that are easy to operate and evolve

Nice to have:

Previous experience at early-stage startups
Contributions to open-source projects
Exposure to AI workflows integrated into production software
Experience with metadata systems, policy-enforced access, or governance tools
Familiarity with Aiven-managed services (Kafka®, PostgreSQL®, OpenSearch®, ClickHouse®)
