Job title: Head of Engineering & Senior Solutions Architect

Role Type: Hands-on Leadership / Strategic

Focus: Architecture, Team Strategy, Backend/Cloud Core, IoT Integration

Role Summary:

We are looking for a Head of Engineering to take ownership of Ionnyk’s technical strategy. You will replace a key leader who balanced high-level architecture with hands-on implementation. You will oversee the entire stack—from the Cloud (GCP/Kubernetes) to the Backend (Kotlin/Spring Boot) and its interaction with our IoT devices. You will act as the bridge between business units, external hardware stakeholders, and the software team.

Key Responsibilities

• Technical Strategy & Leadership: Define the technical roadmap, gather needs from business units, and coordinate internal/external stakeholders. Define and lead the overall technical strategy for the engineering team.

• Architectural Oversight: Define and maintain the global solution architecture for our e-paper frame fleet. Ensure it is robust, scalable, and secure.

• Hands-on Development: Actively contribute to the core backend, utilizing Kotlin, Spring Boot, and complex patterns like CQRS/Event Sourcing.

• Security & Compliance: Act as the Security Officer/DPO, implementing security best practices across the infrastructure. Ensure the implementation and adherence to best practices in IT security.

• Infrastructure & DevOps: Oversee the GCP infrastructure, Kubernetes orchestration, and GitOps deployments via FluxCD.

• IoT & Firmware Strategy: Understand the interaction between the cloud and NRF5-based hardware (BLE, OTA updates, bootloaders) to guide hardware/software integration.

• Business Alignment & Solutioning: Gather requirements from various IONNYK business units, guarantee the implemented technical solutions meet business needs, and identify and propose adapted technical solutions to meet evolving business requirements.

• Coordination: Coordinate all internal and external technical stakeholders.

Required Competencies:

• Backend & Data: Expert in Kotlin (v1.9+) and Spring Boot 3.x. Deep knowledge of JPA/Hibernate and PostgreSQL. Advanced knowledge of Kotlin and Spring Boot 3.x for backend development.

• Architecture & Design: Expert in defining and designing REST API systems. Experience with 3-tier architecture, Hexagonal architecture (Ports & Adapters), and CQRS. Proficiency in architectural patterns like CQRS / Hexagonal is a strong asset.

• Cloud & DevOps: Advanced knowledge of Google Cloud Platform (GCP). Advanced experience with containerization (Docker) and orchestration (Kubernetes), including GitOps (Flux CD). Experience with CI/CD pipelines (GitLab CI).

• Frontend (Web): Advanced knowledge of React and TypeScript for modern web development.

​What’s in it for you:

• ​Strategic Impact: Direct influence on the tech roadmap and product evolution.

• ​Modern Stack: No legacy. Kotlin 1.9+, Spring Boot 3.x, K8s, and Hexagonal Architecture.

•​ Innovation: Work at the intersection of IoT, Art, and Cloud (E-paper tech).

​Ownership: Full autonomy over engineering culture and architectural standards.

​• Flexibility: Hybrid work model and focus on results, not micromanagement.

​• Package: Competitive salary and the best hardware for your setup.
