Job Description
Senior PLC Engineer
Giga Energy
• As a Senior PLC Engineer, you'll own the controls software that keeps our infrastructure online. • This is a hands-on build role. • You'll take an architecture from concept to commissioned, running system, programming the PLCs and SCADA and writing the software, services, and tooling around them. • Design, develop, test, and commission PLC programs on Siemens (TIA Portal, S7-1500/1200) and/or Rockwell/Allen-Bradley (Studio 5000, ControlLogix/CompactLogix) platforms, using IEC 61131-3 languages (Structured Text and ladder), for cooling and mechanical plant equipment: CDUs, chillers, hydraulic skids, fan walls, DOAS, and pumps. • Develop the supervisory logic for the Master Plant Controller, including equipment staging, lead/lag, setpoint reset, failover, and plant-level coordination across multiple skids. • Build and maintain the SCADA/HMI layer (Siemens WinCC, Rockwell FactoryTalk View, or Ignition): operator screens, alarming, trending, historian, and access control. • Write robust safety logic, interlocks, and alarm strategies for pressurized and high-power equipment, and uphold a safety-first engineering standard. • Integrate OEM-controlled equipment such as chillers and DOAS over Modbus TCP, BACnet, OPC UA, EtherNet/IP, and PROFINET, defining and validating register and object maps. • Build process simulations and digital twins (Siemens PLCSIM Advanced / SIMIT, Rockwell Studio 5000 Emulate / Emulate3D, or scripted models) to validate logic and tune control loops before site deployment. • Lead field commissioning, startup, and loop checks. Troubleshoot live systems and drive issues to resolution. • Apply real software engineering practices to controls work: version control, code review, modular and reusable function-block libraries, and clear naming and documentation standards. • Build the general-purpose software around the controls stack: data pipelines, monitoring and telemetry services, edge and cloud integrations, internal tooling, and automation that connects plant data to the rest of Giga's systems. • Translate the controls engineer's architecture and sequence-of-operations into working, well-structured, maintainable code. • Operate comfortably in ambiguous, unstructured environments and solve problems where established processes don't yet exist.
Job Requirements
- 5+ years programming industrial PLCs and SCADA/HMI systems in production environments.
- Deep hands-on experience with Siemens (TIA Portal, S7-1500/1200) and/or Rockwell/Allen-Bradley (Studio 5000, ControlLogix/CompactLogix), fluent in Structured Text and not just ladder. Experience across both platforms is a strong plus.
- Proven SCADA/HMI development experience (Siemens WinCC, Rockwell FactoryTalk View, Ignition, or comparable platform), including alarming, historian, and trending.
- Strong command of industrial communication protocols such as EtherNet/IP, PROFINET, Modbus TCP, OPC UA, and BACnet.
- Experience programming controls for mechanical, process, or HVAC plants (pumps, valves, chillers, heat exchangers, air handling).
- Track record of commissioning systems on live equipment, with a rigorous, safety-first mindset.
- Excellent written and verbal communication, with the ability to work directly with controls engineers, mechanical engineers, and field technicians.
- Willingness to travel to project sites for installation and commissioning.
Benefits
- Subsidized health, dental, and vision insurance
- Equity (options) in a rapidly growing startup
- 401(k) with 4% employer match
- Unlimited PTO
- Parental leave

With a business model that is aligned with our customers, we create transparent, fair, and simple financial products that put money back in the hands of our members, help them spend wisely, avoid unfair fees and build their credit quickly. If autonomy, ownership, and having meaningful input at the company you work for is important to you, come join our growing team! Brigit is doing innovative and exciting work, but don’t just take our word for it, our work is being recognized by others: - Built In's 2026 Best Midsize Companies to Work For in New York City - Built In's 2025 Best Places to Work For In New York City - Built In’s 2024 & 2025 Best Startups to Work For In the U.S. - Built In’s 2023 - 2025 Best Startups to Work For In New York City - Fast Company’s Most Innovative Companies of 2022 - Business Insider’s Most Promising Consumer Startups 2022 - Forbes Fintech 50 2022 Role Overview: Brigit is looking for senior fullstack engineers to help us scale our next-generation consumer finance platform to millions of users in the next year. We’ve found tremendous traction helping low income Americans make ends meet; now is the time to scale. We’ve built a mobile/web app on React and React Native with Typescript, and a backend of Java services in Google Cloud. It’s served us well so far, but we need help making it even better. Our team has two main goals: 1) Feature development supporting numerous external and internal applications. The next generation of our product may look nothing like it does today - and we welcome that! The degree to which we implement new user flows, compute our proprietary algorithms, integrate with 3rd party APIs, store data, and serve traffic will make or break our success. 2) Scalability of our customer-facing applications. Growing from 100k to 10 million users presents unique technical challenges. The efficiency and reliability of both our customer-facing and internal tools needs to improve. We have fun Data Engineering tasks, automation procedures, and availability/monitoring problems to tackle. We also have many user-facing projects, including the creation and upkeep of components and libraries, GraphQL API design, testing and QA processes, and CI/CD enhancements. Our team is small and nimble; you'll be given an extraordinary amount of autonomy and ownership. More importantly, you have a large say in the direction of the company -- both in terms of our technology and our product. Recent accomplishments of our team are: - Building a Payments API platform that moves millions of dollars on a daily basis - Implementing the advanced mathematical processes behind our proprietary risk algorithm - Normalizing relational database schema to optimize for performance for over 1 million users - End to end User notification (via SMS, Email, Push) capabilities - Building internal tools that enable our Customer Support Specialists to help our customers ASAP One of our greatest strengths is the speed at which we move. If you want to propose a new way of doing things, we are all ears. If you have an idea for a new feature, we'll be open to it. A new design paradigm? Bring it on. At Brigit you can enjoy a mature CI/CD platform with automated deployment processes, an easy-to-use local/staging/production development environment, and teammates willing to fill in the gaps. We automate manual things so we can focus on thinking and building something that helps people. As a fullstack engineer we’re looking for someone with experience owning a feature from start to finish on both the frontend and backend. We don’t expect everyone to know everything in our stack, but having one side of overlap (frontend/backend) that you feel very comfortable with will set you up for success here.
