Responsibilities:

• Design and maintain core platform services written in Rust (or Go), powering secure communication, device orchestration, and data pipelines.
• Design robust, scalable APIs, with strong ownership of API contracts, versioning, and long-term evolution across multiple products.
• Model and manage complex data domains, including multi-tenant and multi-product data models.
• Build and operate event-driven architectures, enabling asynchronous communication and scalable system workflows.
• Design and integrate telemetry pipelines, handling time-series data generated by millions of devices securely and efficiently.
• Architect for reliability, observability, and performance at scale, leveraging metrics, tracing, and logging.
• Collaborate closely with product, security, and DevOps teams, ensuring platform capabilities align with business and security requirements.
• Drive architectural decisions, contributing to modularity, maintainability, and long-term platform evolution.
• Mentor engineers and uphold high engineering standards, fostering a security-first and quality-driven culture.

Requirements:

• 6+ years of experience in backend, platform , or distributed systems engineering.
• Senior-level proficiency in Rust or Go, with strong foundations in concurrency, performance, and system design.
• Strong experience in API design, including REST/gRPC, backward compatibility, and cross-service communication.
• Proven experience with data modeling for complex, multi-product or multi-tenant platforms.
• Hands-on experience with event-driven architectures and message-based systems.
• Familiarity with time-series data and telemetry pipelines, especially in high-throughput environments.
• Solid understanding of distributed systems, cloud-native architectures, and Linux-based environments.
• Experience with Docker, CI/CD pipelines, and cloud platforms (AWS or equivalent).
• Working knowledge of PostgreSQL, Redis, and streaming systems such as Kafka or NATS.
• Strong understanding of security principles, including authentication, encryption, identity, and data protection.
• Ability to own systems end-to-end, from design to production operations.

Nice-to-have:

• Previous experience as a platform engineer in a security company or cybersecurity-focused environment.
• Background in IoT, edge computing, or large-scale telemetry systems.
• Open-source contributions, especially in Rust or Go ecosystems.

Why Join Us?

• Join a team shaping the future of secure IoT and embedded technology worldwide.
• Build next-generation cybersecurity solutions that protect data, devices, and users at scale.
• Work across Rust, Linux, distributed systems, and edge computing — solving complex challenges that push performance and reliability.
• Influence architecture, product strategy, and key engineering choices from day one.
• Take ownership, expand your skills, and advance your career in a fast-moving international environment.
