About ONIQ

ONIQ is on a mission to transform manufacturing for a more sustainable and efficient future.

Our entrepreneurial mindset and commitment to innovation have enabled us to grow fast and shape the future of digital lean and green manufacturing. At ONIQ, culture is just as important as product. We foster an environment rooted in authenticity, diversity, integrity, and mutual respect - where everyone is encouraged to bring their whole self to work.

What you will do

As Lead DevOps Engineer, you will be the technical owner of our multi-cloud infrastructure and data strategy. You’ll have real decision-making authority over our cloud architecture, infrastructure roadmap, and data engineering approach as we scale to serve more Fortune 500 enterprises.

This is a hands-on leadership role. You lead through expertise rather than hierarchy: you design, build, and operate key systems yourself while setting the technical direction. You’ll work directly with our founding and senior development team to make critical build-vs-buy decisions, define our infrastructure evolution over the coming years, and establish the foundations that enable our platform and team to scale reliably.

Infrastructure Strategy & Architecture

• Define and execute our multi-cloud infrastructure roadmap, making key decisions on technology selection and architecture patterns
  
• Own the technical strategy for our Kubernetes-based deployment infrastructure and IaC approach across Google Cloud, Azure, AWS, and on-premise deployments
  
• Build, deploy, and monitor container-based services using IaC in diverse client-provisioned Fortune 500 production environments
  
• Interface with enterprise customers technical teams on deployment and infrastructure requirements and rollout plans

• Engineer the DevOps tooling and automation layers that streamline our data onboarding, allowing us to ingest heterogeneous customer data with minimal manual effort
• Own our infrastructure strategy including data (object storage, OLTP/OLAP, caching), CI/CD and orchestration
  
• Develop and optimise APIs and data processing systems using Python (Polars/FastAPI) to benefit from your infrastructure decisions
  

• Partner with product and engineering leadership to translate business requirements into robust infrastructure capabilities
  
• Research and evaluate emerging technologies, making clear recommendations on when and how to adopt new tools
  

What we expect from you

Experience & Technical Depth

• 6+ years in software engineering, cloud infrastructure, or backend/data engineering roles, with a primary focus on Cloud Infrastructure/DevOps and Python proficiency and at least 2 years in a senior technical capacity where you made architectural decisions
• Deep, hands-on expertise with Kubernetes, major cloud providers (Google Cloud, Azure, AWS), and IaC frameworks (Terraform, OpenTofu, Pulumi)
• Strong Python skills with modern data processing libraries (e.g. Polars) and API frameworks (FastAPI, etc.). Experience with TypeScript/React or Rust is a plus, not a requirement

• Track record of making significant architectural decisions and seeing them through to production at scale.
• Strong sense of ownership – you care about outcomes, not just outputs, and you’re happy to roll up your sleeves.
• You prefer deep impact and technical leadership over pure people management.

• Genuine interest in industrial manufacturing and B2B SaaS – we’re solving real problems for customers making physical products
• Entrepreneurial mindset: you enjoy building foundational systems that will support company growth over years
• Excellent organisational and communication skills – you can articulate complex technical decisions to non-technical stakeholders
• Master’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience

• We love the energy that comes from working together in person, so spending time at our Cologne or Berlin office matters to us. One on-site day per week is the minimum, and more time together is always welcome

What we offer

• True technical ownership with decision-making authority over infrastructure strategy
• Direct impact on our ability to serve manufacturing customers and scale the platform
• A culture built on transparency, integrity and authenticity – we trust and respect each other and make decisions based on competence
• A fast-paced, agile environment where you can take on as much responsibility as you feel ready for and actively shape our marketing and go-to-market
• A team that genuinely cares about collaboration and work culture: we regularly reflect on our teamwork, invest work time into team spirit and consciously create balance in everyday work
• The opportunity to contribute to fighting climate change by helping industrial manufacturers to become more efficient and to reduce their CO₂ emissions, while we are mindful of our own environmental impact as a carbon-neutral company
• All the benefits that make work more pleasant: flexible hours, part-time options, remote work possibilities, regular team events and offsites, 30 days PTO, weekly yoga sessions, Deutschlandticket, Urban Sports Club and more
