Senior Real-Time Control Software Engineer

Intellisync; Town of Italy (NY); Hybrid; EUR 80,000 - 120,000; Full time

Job summary

BaxEnergy is seeking a Senior Real-Time Control Software Engineer to implement and optimize deterministic real-time software for our CPPC platform, ensuring low latency and robust behavior under real grid conditions. The role is fully remote, with collaboration across distributed teams and tight hardware integration.

You will translate control algorithms into production-grade real-time code, work closely with control engineers, and contribute to safety-critical software standards.

Qualifications

• 6–10+ years of experience in industrial real‑time software development.
• Strong experience with real‑time programming in C/C++ and IEC 61131-3.
• Hands‑on experience with RT‑Linux or industrial PLC platforms such as Beckhoff, Codesys.
• Direct experience with field controllers, not purely IT systems.
• Understand scheduling, determinism, jitter, and latency — and know how to debug them in practice.
• Able to work with globally distributed teams, with at least a 4‑hour overlap with CET/CEST.
• Eligible to obtain a visa and able to travel to Italy within three months of hiring.

Responsibilities

• Implement and optimize real‑time control loops for active/reactive power, voltage, and frequency (P/Q/V/f) regulation.
• Develop FFR logic, ramping, smoothing, and transient response handling for grid‑connected systems.
• Manage task scheduling, priorities, and jitter to meet strict latency and determinism requirements.
• Optimize CPU utilization, I/O handling, and communication latency.
• Collaborate closely with Control Engineers to translate control algorithms into robust real‑time implementations.
• Debug, profile, and stabilize real‑time behavior under realistic and stressed grid scenarios.
• Contribute to coding standards and best practices for safety and performance‑critical software.

Job description

We’re looking for a Senior Real-Time Control Software Engineer to implement and optimize the deterministic real-time software of our CPPC platform. In this role, you’ll be responsible for ensuring strict timing guarantees, low latency, and stable behavior under real grid conditions for utility-scale renewable energy and storage systems.

This is a deeply technical, hands‑on role for someone who understands what deterministic really means. You’ll work close to the hardware, translate control algorithms into production‑grade real‑time code, and make systems behave correctly when timing, jitter, and edge cases actually matter.

This role is fully remote.

What You Will Do

• Implement and optimize real‑time control loops for active/reactive power, voltage, and frequency (P/Q/V/f) regulation
• Develop FFR logic, ramping, smoothing, and transient response handling for grid‑connected systems
• Manage task scheduling, priorities, and jitter to meet strict latency and determinism requirements
• Optimize CPU utilization, I/O handling, and communication latency
• Collaborate closely with Control Engineers to translate control algorithms into robust real‑time implementations
• Debug, profile, and stabilize real‑time behavior under realistic and stressed grid scenarios
• Contribute to coding standards and best practices for safety and performance‑critical software

Why Join Us

You will join a fast‑growing technology company operating in a complex and challenging industrial and energy environment, where software and engineering innovation has a real impact on systems and infrastructure.

We work on highly complex projects that require strong technical expertise, ownership, and close collaboration across multidisciplinary teams (software, control, automation, operations).

Positions are open both to professionals working as contractors and to candidates interested in on‑site employee roles, depending on the profile, experience, and project needs.
We welcome applications from local candidates, available to work on‑site, as well as from professionals based worldwide, in line with the applicable contractual model.

We offer a dynamic, results‑oriented work environment, where people are actively involved in projects and valued for the contribution they bring
