Senior Research Engineer – Hybrid in Montréal

At LocusX, we’re aiming to steadily revolutionize the Software Development Life Cycle (SDLC) and reimagine the game development pipeline by embedding intelligence at its core. Our platform uses ML to automate testing, debugging, and production insights—helping studios ship faster, smarter, and more reliably. Founded by gaming and AI veterans, we’re building a research-driven culture where cutting-edge ideas turn into real-world breakthroughs.

About The Role

We’re seeking a Senior AI Researcher to lead our efforts in exploring, prototyping, and validating novel AI techniques that can transform game development workflows. You’ll work on the frontier of LLM reasoning, context understanding, multimodal AI, and AI-human collaboration, with an emphasis on bringing research concepts to production readiness. This role blends pure research curiosity with practical product impact—you’ll have the freedom to explore ambitious ideas, but also the responsibility to see them deliver measurable results for our customers. The position is full-time and is based in Montreal, Canada. The work model is hybrid.

Compensation: Competitive salary and equity.

In This Role, You Will Be:

• Conducting research on advanced AI architectures relevant to game development pipelines, tackling challenges such as dynamic changes, data privacy, correlation, and causal discovery.
• Prototyping and evaluating AI agents capable of operating within complex development pipelines.
• Developing and testing novel algorithms to interpret and reason over production data (e.g., bug reports, code commits, game assets, logs).
• Building various components of the multimodal stack: datasets, modelling, evaluation, deployment and more.
• Collaborating with production and engineering to find important research directions that match our roadmap and turn research results into scalable, production-ready solutions.
• Staying at the forefront of AI research by publishing internally and potentially externally if appropriate.
• Being a key technical voice in the company, helping shape product roadmap and culture.

You May Be a Good Fit If:

• You have a Master/PhD or equivalent industry research experience in AI, ML, NLP, or a related field.
• 5+ years of AI research, with a proven track record of innovation and peer-reviewed publications or have significant software, ML, or research engineering experiences.
• Strong engineering skills, particularly in designing, deploying and optimizing multiple AI systems.
• Enthusiasm for staying at the forefront of technology trends and a commitment to continuous learning.
• Prior work in startups, in gaming and/or developer tooling environments.
• The ability to bridge the gap between research novelty and product value.

You Might Thrive in This Role If:

• You are a team player, willing to do a variety of tasks that move the team forward, preferring fast-moving collaborative projects to extensive solo effort.
• You have experience working with large size multimodal models including temporal sequences of text, audio, image and video.
• You have deep knowledge of neural network algorithms, trends in ML space and challenges associated with SaaS deployment including privacy, data-quality and real-time decisions.
• You show strong problem-solving skills and ability to identify technical improvements in complex systems and enjoy obsessively iterating on immediate blockers towards long-term goals.
• You care about the real-world impact of AI.
• You have strong attention to detail.

Strong Candidates May Also:

• Have experience with LLMs and Agentic AI.
• Have experience with Graph neural networks and common vision backbones.
• Have experience with Transfer Learning, Federated Learning and Reinforcement Learning.
