Job Description:

We’re looking for a Staff Software Engineer to join our Aiven Unify team. Aiven Unify’s mission is simple: help customers quickly discover, govern, and query their data—delivering value in minutes, not months. 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.

Job Responsibility:

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

Requirements:

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 ingestion
REST API design and integration — building, securing, and maintaining user facing, service-to-service APIs
Java languages (Java) for improvements and integrations of managed services
React/TypeScript for occasional Console UI enhancements
Experience 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®
