• Responsibilities:

  Responsible for ensuring the reliability and quality of telemetry‑driven IIoT systems through advanced troubleshooting, manual testing, and protocol‑level diagnostics across edge and cloud environments.
  The L2 Support Engineer / Manual QA Engineer is responsible for second‑line support and quality validation of IoT and IIoT systems handling real‑time telemetry data. The role investigates complex issues escalated from L1, performing root‑cause analysis using logs, metrics, telemetry streams, and monitoring tools. It involves diagnosing problems across edge and cloud environments, often running on Linux‑based systems. The engineer validates fixes and configuration changes before production release and collaborates closely with development, DevOps, and L3 teams.
  In parallel, the role performs manual functional, integration, and regression testing across UI, API, and backend layers. A key responsibility is validating end‑to‑end data flows from devices and gateways through brokers and backend services to dashboards and reports. The engineer ensures data accuracy, correct aggregation, timestamp alignment, and proper resolution in time‑series data.
  The role requires hands‑on work with industrial and IoT protocols such as Modbus and MQTT, including validation of payloads, connectivity, and reconnection behavior. It also involves using monitoring and diagnostic systems to detect latency, data loss, or anomalies in real‑time systems. Overall, the role ensures system reliability, data quality, and observability while supporting continuous improvement across support and QA processes.

We are looking for a Senior PHP Developer with a strong architectural mindset to lead the development of our core systems. You won't just be writing code; you will be responsible for the technical excellence of the product. You will design complex business domains, mentor middle developers, and ensure that our Symfony-based applications remain modular, testable, and resilient under high load.

Technical Leadership Requirements:

• Expert PHP 8.3+: Deep understanding of the engine, memory management, and performance optimization.
• Symfony Mastery: Expert knowledge of internal framework mechanics (Compiler Passes, Custom Lexers/Parsers, advanced Security configurations).
• Architectural Patterns:
  • Practical experience with DDD (Domain-Driven Design): Bounded Contexts, Aggregates, Value Objects.
  • Deep understanding of CQRS and Event Sourcing (and when not to use them).
  • Strategic Design: Ability to define boundaries between modules/microservices.
• Infrastructure & Messaging:
  • Experience with Distributed Systems: Handling eventual consistency, saga patterns, and distributed transactions.
  • Advanced use of message brokers (RabbitMQ/Kafka) with focus on Reliability (Outbox pattern, Idempotency).

• Testing & QA: Driving the testing strategy (Unit, Integration, E2E, Contract Testing).

   

Good to Know:

• Ecotone Framework: We highly value the ability to implement Message-Driven Architecture using Ecotone.
• Knowledge of how to decouple the Domain layer from the Infrastructure (Symfony/Doctrine) using Ecotone's declarative approach.

• Experience in migrating legacy "Fat Services" to a decoupled, event-driven model.

   

Key Responsibilities:

• System Design: Architecting new modules from scratch, choosing the right patterns for the specific business problem.
• Mentorship: Conducting deep code reviews and holding "Tech Talks" to elevate the team's understanding of DDD and Clean Code.
• Technical Debt Management: Proactively identifying architectural bottlenecks and leading refactoring initiatives without halting product delivery.
