Job description

Location: on-site/remote aligned with European CET/CEST

Reporting to: CTO

Start date: ASAP

At OTee, we are rethinking industrial automation from the ground up. Our momentum is driven by a clear market need across geographies and a strong support from strategic, international investors. If you've been looking for a place where your work can shape an entire industry (and where you'll feel the energy of real progress every day), this is it. You'll be joining a lean but growing team that values curiosity, technical excellence, and impact.

About the Role

As Backend Developer (Platform & Reliability) at OTee, you will build out the backend services that power our platform. You will work alongside the existing backend team - contributing to shared architecture decisions, owning the CI/CD and observability surface, and holding backend systems accountable to a 99.95% availability target.

Key Responsibilities

• Build Platform Backend Services: Build and maintain services that integrate the platform's data layer, messaging fabric, and external interfaces - production implementations in Go and/or Python, deployed on cloud Kubernetes with on-prem variants depending on customer context.
• Contribute to Backend Architecture Decisions: Co-own architectural decisions with the existing backend team across data modeling, messaging semantics, service boundaries, and cloud/on-prem deployment trade-offs.
• Own CI/CD Pipeline Development and Reliability: Develop, maintain, and improve CI/CD pipelines (GitHub Actions, CircleCI) and GitOps deployment workflows (ArgoCD on EKS) for pipeline performance, reliability, and developer ergonomics.
• Drive Backend Reliability Toward a 99.95% SLA: Own observability for backend services on the new Prometheus/Grafana infrastructure, establish reliability practices for distributed systems, and participate in incident response events where necessary.

What We're Looking For

At OTee, we're building a world‑class team - people who strive to be the best version of themselves and bring speed, precision, and care for the systems they build. If you're excited by the idea of setting new standards in industrial automation, you'll fit right in.

Education & Experience

• 5+ years of backend development experience, with significant time spent on architecture and system design
• Has designed and operated multiple microservices in production
• Has built and operated pub/sub / event-driven messaging in production, with a track record of making the calls these systems demand: delivery semantics, schema, ordering, error handling
• Has built and maintained CI/CD pipelines (GitHub Actions, CircleCI, or equivalent) - pipeline performance, reliability, and developer ergonomics, not just running templates
• Has deployed and/or operated observability infrastructure (Prometheus, Grafana, or equivalent) in distributed systems beyond consuming dashboards built by others
• Has handled production incidents in distributed systems
• Deep understanding of relational database design and modeling (PostgreSQL or equivalent)
• Production experience with Docker and Kubernetes, ideally with GitOps (ArgoCD) and AWS-managed services such as EKS and RDS
• Production experience with Redis for caching, session, or state management
• Strong API design experience REST, gRPC, OpenAPI/Protobuf contracts
• Excellent communication and collaboration abilities
• Nice to have: exposure to industrial protocols (OPC UA, MQTT)

(Technical) Skills

• Languages: Golang and/or Python
• Architecture: Microservices, Event-Driven Architecture, DDD
• Databases: PostgreSQL, Redis, RDS instances (NoSQL a plus)
• Messaging: NATS preferred (Kafka/RabbitMQ also relevant)
• Containerization & Orchestration: Docker, Kubernetes
• CI/CD: GitHub Actions, CircleCI, ArgoCD
• Monitoring: Prometheus, Grafana

Personal Qualities

• Ownership of shared responsibility: You feel full responsibility for the backend function and are able to make sure all required functionalities and components are delivered to high quality and in a timely manner, independently and as a team
• Reliability mindset: You design and ship services with their failure modes, observability, and recovery paths in mind from day one, not as an afterthought
• Collaborative Spirit and Communication: Strong team player with excellent interpersonal skills
• Attention to Detail: Ensuring high-quality, technical solutions that adhere to industry standards and best practices
• Strategic Thinking: Strong understanding of technical trade-offs and ability to balance performance, scalability, and maintainability with business objectives
• Interest in Industry 4.0: extra brownie points if you know what a PLC is and understand OT/IT security convergence

What We Offer

• The opportunity to take part in building a product with global impact
• What may be the biggest challenge of your professional career
• A competitive benefits package with stock options
• Being part of an exceptional team, with experts in their respective fields
• An honest work culture where we can admit failures, ask for help and be safe
