Who is Litmus

Litmus is building the data foundation that powers industrial AI.

AI doesn’t work without real-world, contextualized data - Litmus makes that data usable. As AI adoption accelerates, most industrial environments still can’t access or use their operational data. We solve that gap.

We’re a growth-stage software company helping manufacturers access, structure, and use real-time data from machines, systems, and sensors at the edge. Our platform sits at the intersection of edge computing, AI, and industrial operations, enabling some of the world’s largest companies to run operations in real time, reduce downtime, and optimize production.

Backed by leading investors and trusted by global manufacturers and partners like Google, Microsoft, Dell, Oracle, and Mitsubishi, Litmus is powering the shift toward software-defined manufacturing.

Why join Litmus

Build the infrastructure that makes industrial AI possible

AI is moving beyond the cloud and into the physical world. At Litmus, you’ll build the infrastructure that enables real-time data to power AI and machine learning systems in production environments.

Work on problems where software meets the real world

Most AI systems fail without access to real-world data. You’ll build the layer that makes them viable in production. We solve challenges at the intersection of distributed systems, real-time data, and industrial constraints — where reliability, scale, and performance are non-negotiable.

Have real impact, fast

You’ll work on systems used by real customers in production, with direct impact on product and company trajectory. As a scaling company, we move quickly. You’ll have ownership, visibility, and the ability to shape both product and company as we scale.

Join a high-performance team

We’re building a team that holds a high bar and pushes each other to improve. You’ll work alongside experienced operators, engineers, and leaders who have done this before and are building again at scale. We hire people who take ownership, move quickly, and care about outcomes. No passengers.

Our culture

At Litmus, the team is collaborative, curious, and low ego. People are scrappy, take ownership, and look for ways to make an impact. We value empathy just as much as execution, whether that’s in how we build, how we communicate, or how we support each other.

We’re a growing company, so things move quickly and not everything is perfectly defined. If you enjoy figuring things out, working closely with others, and making steady progress, you’ll do well here.

Description

As a Software Engineer – Golang Developer, you will play a pivotal role in developing southbound connectors in Golang. These connectors enable seamless data exchange between Litmus Edge Products and a wide range of IIoT devices, industrial protocols, PLCs, and operational technology (OT) systems.

Your primary responsibility will be to design, implement, and maintain robust connectors that keep communication between our software and the OT layer reliable, secure, and efficient. Your work will be essential in helping our products scale and adapt to ever-evolving industrial environments.

What you will do

Design and develop high-performance, Golang-based southbound connectors that communicate with industrial devices and control systems using protocols such as OPC-UA, Modbus, EtherNet/IP, PROFINET, and DNP3.

Implement support for IIoT protocols such as MQTT, CoAP, and SOAP, enabling effective communication with industrial devices and sensors.

Build connectors for streaming protocols such as WebSockets and HTTP/2, enabling real-time data streaming and communication with external systems.

Implement robust error handling and fault-tolerance mechanisms so connectors stay resilient to failures and deliver a seamless user experience.

Collaborate with cross-functional teams, including product managers, OT/controls engineers, and other developers, to understand requirements and deliver high-quality integration solutions.

Conduct thorough testing, including unit, integration, and hardware-in-the-loop tests, to validate the functionality and performance of connectors.
