Original job description

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.

As a Senior Software Engineer specializing in Golang, you will play a pivotal role in developing southbound connectors that enable Litmus Edge to communicate reliably with PLCs, industrial control systems, and IIoT devices.

You'll work at the intersection of modern software engineering and industrial automation, solving complex communication challenges across a wide range of protocols, devices, and manufacturing environments. Your work will directly enable customers to securely connect their factory-floor systems to the Litmus platform.

You won't get bored in this role - you'll be exposed to a constantly evolving range of protocols, devices, and industrial environments across industries. You'll work with an exceptional team using modern tools to push the boundaries of industrial communication, speed, and reliability.

What You'll Do:

Develop primarily Golang-based southbound connectors that communicate directly with PLCs and industrial control systems using protocols such as OPC-UA, Modbus, EtherNet/IP, PROFINET, and DNP3.
Implement robust error handling and fault-tolerance mechanisms to ensure connectors are resilient to failures in OT environments and deliver a seamless user experience.
Troubleshoot and optimize connector performance, reliability, and communication across diverse industrial environments.
Design and implement comprehensive testing, diagnostics, logging, and monitoring to identify and resolve communication issues across diverse OT environments.
Collaborate with cross-functional teams - including Product Managers, OT/Controls Engineers, and other Software Engineers - to understand requirements and deliver high-quality integration solutions.
Contribute to the development of our open-source projects, sharing expertise with the wider developer community.

What We're Looking For:

Must Haves:

Bachelor's or Master's degree in Computer Science, Software Engineering, Electrical Engineering, or a related field.
Hands-on experience developing software integrations, connectors, or drivers for PLCs and industrial control systems, with practical knowledge of industrial protocols such as OPC-UA, Modbus, EtherNet/IP, or PROFINET.
Strong proficiency in Golang.
5+ years of relevant software engineering experience.
Deep understanding of networking concepts, real-time communication, and industrial automation environments.
Strong communication skills and the ability to collaborate effectively with cross-functional teams, including engineers from both software and industrial automation backgrounds.

Nice To Haves:

Experience with C++
Experience with MQTT, REST, SOAP, and other communication protocols.

Compensation Range: CA$125K - CA$170K
