Department: Consulting

Employment Type: Full Time

Reporting To: UX Team Lead

n

Description The Decision Lab is an applied behavioral science consulting firm based in Montréal.

n

Our mission is to democratize the insights generated by behavioral insights to help people live better lives.

n

We're a young company, but we punch above our weight: in the past, we've worked with partners like the Gates Foundation, Capital One, and the World Bank, using scientific thinking to tackle some of the thorniest problems of our day.

n

Everything we do at TDL is guided by SPICE: Socially conscious, Pragmatic, Inventive, Catalytic, and Evidence-based.

n

Why this role is important for TDL

n

We're not looking for a "pixel pusher."

n

We're looking for a Sr.

n

Product Designer —someone who thrives at the intersection of UX, UI and strategy.

n

Our team goes beyond screens: we design products, yes, but we create systems, workshops, toolkits, communications, and experiences that create change and solve complex problems.

n

That means we're looking for a problem solver first, designer second—a person who can bring clarity, creativity, and evidence-driven thinking to challenges of all shapes and sizes.

n

Why this role is great for you The Decision Lab is a place where you can learn to use evidence-based approaches to solve diverse & complex challenges.

n

You will work alongside intelligent & free-thinking colleagues who lead with optimism, pragmatism and empathy.

n

Rather than reusing the same behavior change frameworks,



TDL develops custom solutions – this means that in addition to being evidence-based, your role will be fundamentally creative and you will have the opportunity to evolve and express your thinking in the work you do.

n

Our team helps and empowers each other and we have a rich set of tools and frameworks that you will be exposed to, but you will ultimately be responsible for your work – past hires tell us they are surprised to what extent they are able to take intellectual ownership of the projects they work on.

n

What you'll do

n

Own the end-to-end design process—from research and strategy to wireframes, prototypes, user testing, and delivery.

n

Translate research and behavioral insights into actionable design solutions and interventions that are both evidence-based and intuitive.

n

Create visual interfaces while building experiences that balance form and function.

n

Work beyond product screens: make research insights tangible, design workshop experiences, and create compelling communication tools.

n

Lead clients and colleagues through design decisions—explaining the why with clarity and confidence.

n

Drive projects forward by clarifying priorities, managing iterations, and ensuring alignment with strategic goals.

n

Collaborate with behavioral scientists and strategists to apply AI ethically in products and processes, ensuring transparency and user trust.

n

What we are looking for

n





5+ years of professional experience blending UX, UI, and design strategy.

n

A portfolio that shows not just polished visuals, but your process and thinking.

n

Experience in conducting and applying research—usability testing, surveys, co-design, and more—to inform decisions.

n

Strong communication skills for both internal collaboration and client-facing conversations.

n

You're curious about emerging tech and comfortable experimenting with AI to expand the range of design solutions.

n

Comfort with ambiguity, non-hierarchical organizations, and environments where everyone's voice matters.

n

Enthusiasm for behavioral design (or willingness to learn).

n

Have experience in the health space, or designing with equity and inclusion at the forefront.

n

Bring a graphic or visual design background—skilled at making complex ideas simple and compelling.

n

Thrive at working with diverse roles and perspectives, using collaboration as a way to push projects forward and raise design quality.

n

Eager to introduce new practices to improve design maturity.

n

A jack of many trades who can move fluidly between research, strategy, and design execution.

n

Evidence-driven, not ego-driven—you let testing, iteration, and impact guide your choices.

n

Adaptable, collaborative, and excited to design in contexts where the challenge isn't always a screen.

n

Motivated by creating solutions that make a difference—not just products that "look good."

n

About the role

n

6m contract role with the possibility of renewal and/or permanent position

n

Remote position (with at least 80% overlap with Montreal timezone)
