Staff Software Engineer

Aiven Unify’s mission is simple: help customers quickly discover, govern, and query their data—delivering value in minutes, not months.Here’s a short pitch from the Product Director behind this initiative: “I'm building a small, fast-moving team inside Aiven - think startup energy, minimal process, and full ownership. The goal is to launch new open-source managed services that will drive a platform effect for Aiven, including a Data Catalog, a Federated Query Engine, and other technologies to help our customers do more across their data stack. Basically trying to make an open-source first data platform.”We’re looking for engineers with experience across Python, REST APIs, Java, React/TypeScript, understanding of PostgreSQL, OpenSearch, Kafka, Terraform, and cloud infrastructure to help us build and scale these next-generation data services.The Role:We’re looking for a founding Staff Engineer to lead the way—someone who can architect, ship, and run this service. Think of this role as the “CTO of the team”: you’ll set the technical direction, design the early architecture, define SLOs, and contribute to open-source. If you’re interested in eventually moving into engineering management, that path is open.We work like a startup inside Aiven: fast shipping, tight feedback loops, and treating mistakes as opportunities to learn. Our focus is on mid-market customers who need simple, open solutions that just work.What You'll Do:Design and own the architecture for running managed services (including VPC support), backed by Aiven-managed data systems (Kafka®, OpenSearch®, PostgreSQL®, and other technologies).Ensure reliability and resilience: design failover mechanisms, deployment patterns, upgrade strategies, and observability for metrics, logs, and traces.Develop and maintain ingestion pipelines and connectors (primarily in Python) to collect and synchronize metadata across Aiven services.Implement identity and access control synchronization, aligning Aiven’s Teams and Roles with catalog-level RBAC/ABAC policies across APIs and UIs.Collaborate cross-functionally with Product, Design, Security, and Platform teams to define SLOs, readiness checklists, and operational runbooks.Iteratively build the product 0 from PoC through LA to GA — balancing speed, quality, and long-term maintainability.Contribute across the stack where needed: Python for orchestration, Java for service improvements and fixes, and React/TypeScript for Console experience improvements.Coach and mentor engineers, set technical standards, and shape the engineering culture for the new product line.What We're Looking For:Strong experience building and operating managed services or SaaS platforms (single- or multi-tenant): tenancy models, and incident management.Hands-on engineering skills, particularly in:Python for service orchestration, platform development and ingestionREST API design and integration — building, securing, and maintaining user facing, service-to-service APIsJava languages (Java) for improvements and integrations of managed services.React/TypeScript for occasional Console UI enhancementsExperience with metadata, catalog, or data pipeline systems: relational databases (PostgreSQL/MySQL), search engines (OpenSearch/Elasticsearch), and event logs (Kafka).Cloud and platform experience: Terraform/IaC, networking (VPC peering/BYOC), observability, and cost optimization.Security mindset: experience with access control, audit trails, GDPR, ISO, and SOC2 compliance.Product sense and delivery focus: ability to work iteratively with design partners and turn concepts into customer-ready services.Nice to have:Contributions to open-source projects.Prior experience working in startups as one of the first hires or co-founder.Experience with policy-enforced access for queries (row/column filtering, masking).Familiarity with Aiven services like Kafka®, PostgreSQL®, OpenSearch®, ClickHouse®Don’t worry if your experience doesn’t line up perfectly – we still encourage you to apply!
