Senior Technical Writer

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.

About the Role:

We are looking for a Senior Technical Writer who takes an AI-first approach to documentation. You will own end-to-end technical content for our industrial edge platform, working across multiple concurrent product releases, collaborating with cross-functional teams, and producing both written and video content that helps customers succeed with our product.

What You'll Do:

• Use AI tools as the default approach to drafting, structuring, reviewing, and maintaining documentation, rather than as an occasional aid.
• Own and manage technical documentation across multiple concurrent product releases, tracking version- specific changes and ensuring accuracy across all live versions.
• Plan, script, and produce video content (feature walkthroughs, release demos, how-to guides) in addition to written documentation.
• Get hands-on with the product directly, testing features and workflows first hand to validate documentation accuracy rather than relying solely on specs.
• Partner closely with Product Management, Engineering, QA, and Support to gather release information, clarify feature behaviour, and align content timelines with release schedules.
• Translate complex technical and industrial concepts into clear, accessible content for varied audiences (OT engineers, plant managers, system integrators, enterprise architects).
• Maintain and enforce documentation style guides and standards for consistency across all content types.
• Build and maintain reusable content templates, review checklists, and AI-assisted content workflows to scale documentation output.
• Manage documentation release schedules independently, prioritizing across multiple in-flight projects.

What You'll Bring:

Must Have

• 5+ years of technical writing experience, ideally in B2B SaaS, industrial, or enterprise software.
• Demonstrated experience using AI tools (e.g., Claude, ChatGPT, Copilot) as a core part of a content workflow, not just for occasional edits.
• Proven ability to manage documentation across multiple simultaneous product releases without losing accuracy or version control.
• Experience creating video content: scripting, recording, and basic editing (tools such as Loom, Camtasia, or similar).
• Strong track record of working cross-functionally with Product, Engineering, and Support teams.
• Comfortable getting hands-on with technical products; able to independently test and validate features.
• Excellent written English, with a clear, concise, technical-but-accessible style.
• Familiarity with documentation tooling (e.g., Markdown, static site generators, headless CMS, Git-based workflows).
• Must be based in Canada and legally eligible to work in Canada.

Nice to Have

• Experience in industrial automation, IIoT, or edge computing domains.
• Experience building or customizing AI-assisted documentation or review workflows.
• Familiarity with API documentation and developer-facing content
