Durin
Overview
Durin was founded under the belief that raw materials should not be a constraint on civilization's progress. We are actively developing the technologies to make this possible, with the ultimate goal of becoming the foundation of the global supply chain.
We’re looking for a Senior Controls Engineer who wants to
own the brains of our next-generation drill rigs,
building the PLC logic that makes heavy equipment safe, reliable, and ready for autonomy.
Durin builds and operates automated drill rigs to accelerate mineral discovery.
Base pay range $150,000.00/yr - $180,000.00/yr
Responsibilities
Architect and program PLC logic for drill cycle sequencing, safety interlocks, mud mixing, spindle/feed coordination, and rod handling
Implement state machines, PID loops, and interlock matrices in IEC 61131-3 languages (Structured Text, Ladder, FBD)
Commission control systems on physical rigs: wiring checkout, I/O validation, drive tuning, field debugging
Collaborate with mechanical, electrical, and software engineers to define sensor/actuator requirements and ensure reliable integration
Design alarm handling, recovery routines, and HMI interfaces for drillers
Ensure compliance with industrial safety standards (STO, SIL, lockout/tagout)
Support networking and fieldbus integration (EtherCAT, CANopen, OPC UA)
Mentor embedded/software teammates on PLC fundamentals and best practices
Travel to test sites for commissioning and field support (20–50%)
Qualifications
5+ years of experience programming and commissioning industrial PLCs (Beckhoff, Siemens, Allen-Bradley, or similar)
Deep familiarity with IEC 61131-3 languages, especially Structured Text and Ladder
Hands-on experience commissioning machinery with hydraulics, servos, and safety interlocks
Strong knowledge of fieldbuses (EtherCAT, CAN, Profibus, Modbus) and industrial networking
Experience tuning closed-loop systems (PID, torque/force control)
Comfort working in rugged field environments with heavy equipment
Strong debugging instincts and ability to rapidly troubleshoot I/O, sensors, and motion issues
“Get it working, get it safe, then get it elegant” mindset
Bonus Points For
Experience with drilling rigs, mining equipment, robotics, or other heavy machinery
Knowledge of safety PLCs, SIL/PL standards, and functional safety certification
Background in both PLC controls + embedded/robotics software
Prior work on automation systems that integrate with edge/cloud telemetry
Additional Requirements
Must be willing to work from our headquarters in El Segundo
Must be willing to work extended hours and weekends as needed
Join Durin to build the future of mining. If you're passionate about making a real-world impact and solving complex challenges, we'd love to hear from you.
Compensation This role will pay $150,000–$180,000, plus equity, so you have a real stake in Durin's success. Everyone is an owner, so as the company grows, your equity grows too.
Aside from base compensation, we invest heavily in our team. You'll have the freedom and resources to try new things and iterate quickly. We're a high-growth company without middle management, which means fast decision making and the ability for you to own major initiatives from day one.
We also offer 100% healthcare coverage (medical, dental, vision), all meals (breakfast, lunch, dinner) are paid for when you're at headquarters, and we can help you find housing nearby.
