Job Description

About 3Sigma EdTech

3Sigma builds classroom analytics and assessment-support tools for schools and educators. We work closely with schools to improve visibility into student learning while fitting as smoothly as possible into existing teaching and assessment workflows.

We are an early-stage, founder-led education technology company with a small international team. Design contributors work closely with founders, product and engineering, and may contribute across both product interface design and broader visual communication needs.

Role Summary 

We are looking for a motivated early-career UI/UX product designer with strong visual-design fundamentals who can contribute primarily to product features and workflows, while also supporting selected website, presentation, brand and communication-design needs.

This is primarily a product-design role focused on UI/UX work for product features and workflows, together with broader design support for website and landing-page visuals, presentation decks, simple brand collateral, logos and icons, business cards, and selected print or communication materials.

It is best suited to someone with strong product-design instincts, a good eye for visual design, solid layout judgment, and an interest in combining structured interface-design work with practical day-to-day visual execution.

Applicants whose experience or portfolio is focused mainly on graphic design, illustration, animation, video, social media or branding should also demonstrate substantive UI/UX or digital-product work.

The successful candidate should be comfortable taking ownership of defined design tasks and carrying them through from requirements and initial concepts to developer-ready or final design output.

We can accommodate near-term academic or other commitments where appropriate, particularly during an initial trainee or contributor period.

Role Responsibilities

• Translating rough ideas into sketches, wireframes, mock-ups, interactive prototypes, and final design assets for new features and improvements 
• Collaborate with product, engineering, and other stakeholders on ongoing feature and product design initiatives 
• Participate in design reviews, contribute to ideation sessions, and help translate research or product insights into design decisions 
• Document design rationales, maintain component libraries, and contribute to shared design and product knowledge 
• Contribute to the design system and help maintain consistency across product interfaces 
• Maintain visual consistency across product UI, website materials, slide decks, and other design outputs 
• Conduct product, competitor, and market research to support product decisions, business discussions, and presentation materials 
• Create or refine website graphics, landing-page visuals, and other public-facing design assets 
• Support the layout and visual refinement of presentation decks, internal documents, and other communication materials, including print and branded communication materials 
• Help produce brand and communication materials, including logos, icons, business cards, print collateral, and related brand assets where needed 

Engagement Structure

Depending on candidate location, availability, experience, and the final arrangement, the opportunity may initially be structured on a trainee, part-time, contract, or independent-contractor basis, subject to applicable law.

Job Requirements
