About Hayla

Hayla is building the intelligent direct current (DC) power layer for next-generation AI infrastructure. As data centers transition to higher-efficiency, high-voltage DC architectures — including emerging 800-volt systems — new hardware and control layers are required to deliver power with precision, safety, and real-time responsiveness. Hayla is developing that platform.
We are a pre-seed company backed by leading investors and operators. Joining now means helping define the architecture, engineering culture, and technical foundations of a new category in AI power systems.

The Role

We are seeking an AI-native electrical engineer who enjoys designing real hardware, modeling complex electrical systems, and turning concepts into validated prototypes. You will work across simulation, circuit design, gate-driver development, protection and sensing, and high-power lab testing. This role also involves collaboration with embedded controls, thermal/mechanical engineering, and system-level modeling.
AI driven development has enabled much faster prototyping cycles. The team is focused on leveraging modern tooling to move as quickly as possible. This includes managing agents, training models and taking AI to places it has not historically been.

What You’ll Do

• Design and prototype power conversion, switching, and distribution circuits for DC systems, including 800-V-class architectures
• Develop gate driver circuits for fast-switching, modern semiconductor devices
• Perform modeling and simulation across electrical, thermal, and system domains (SPICE and similar tools)
• Implement protection and sensing circuitry for current, voltage, temperature, and fault conditions
• Conduct iterative hardware bring-up, characterization, and validation using high-power lab equipment
• Optimize PCB and mechanical layouts for switching performance, thermal reliability, EMI/EMC, and manufacturability
• Collaborate with embedded and controls engineers to integrate digital control interfaces (MCUs, DSPs, FPGAs, or similar platforms)
• Design hardware that supports dynamic power routing and rapid reconfiguration under real-time control
• Participate in design reviews, documentation, component selection, reliability assessments, and structured test planning
• Work cross-functionally with system architecture, thermal/mechanical engineering, and compute/power infrastructure teams to ensure system-level integration
• Help shape lab workflows, test procedures, and engineering practices for high-voltage development

What We’re Looking For

• 3+ years of experience designing, prototyping, and testing power electronics systems
• Extreme familiarity with the latest AI development approaches (Claude, Codex, Agents, Agent Harnesses)
• Strong foundation in high-voltage or high-power converter topologies and semiconductor behavior
• Hands-on experience with gate-driver design and fast-switching architectures
• Proficiency with simulation tools (SPICE variants, PLECS, PSIM, or similar platforms)
• Confidence working with high-power and high-voltage lab equipment
• Experience debugging challenging electrical issues across switching, timing, sensing, and protection domains
• Ability to drive designs from schematic → layout → prototype → validated hardware
• Comfortable working in a small, high-ownership environment with fast iteration cycles

Bonus Points

• Experience with medium- or high-voltage DC systems from EV, industrial power, telecom, renewable, or data center environments
• Exposure to embedded or digital control architectures and real-time control systems
• Familiarity with high-current interconnects, bus bars, thermal/mechanical integration, insulation coordination, and creepage/clearance design
• Background in reliability engineering, derating analysis, safety reviews, or power-system compliance standards
• Experience with lab setup, equipment selection, or building new testing workflows
• Prior startup, R&D, or zero-to-one hardware development experience

Why Join Hayla

• Build foundational technology for the future of AI data-center power
• Opportunity to design and work in a modern and evolving workflow
• Unlimited access to tools and software to move quickly
• Take broad ownership across power hardware, system integration, and real-time control
• Work in a fast-moving environment where designs become real hardware quickly
• Competitive compensation with meaningful early-stage equity
• Collaborate with a senior, multidisciplinary team across power, controls, embedded systems, and AI infrastructure

Compensation

The base pay range for this role is $110,000 – $250,000 per year.
