Job description

Lead Product Designer (UX/UI)

Poland-based | B2B consultancy agreement


About the role


We’re looking for a top-tier Lead Product Designer to own and elevate the user experience across our digital products: our client portal, mobile app, and the interfaces that bridge our hardware with software.


You’ll work end-to-end: from discovery and problem framing through wireframes, prototypes, and high-fidelity UI, all the way to collaborating with engineering on implementation. You’ll join forces with our product team, engineers, logistics & operations teams, and leadership to design experiences that make shipping high-value goods (€5k–€100k) feel intelligent, transparent, and safe.


Seniority & impact: this is a high-ownership role with direct access to decision-makers, a strong quality bar, and significant influence on product direction.

We’re especially looking for someone who is:

  • A strong visual tastemaker with unmatched aesthetics and attention to detail

  • Exceptionally strong in product discovery, keeping users’ needs and expectations at heart

  • Eager to take ownership and take a proactive stance to influence the way we develop our products

  • Fluent in Figma and modern AI-powered prototyping tools (v0, Lovable, etc.)

  • Comfortable in a hardware–software context with real-world constraints (sensors, devices, physical flows)


About the Company


We provide smart, reusable packaging and logistics intelligence for high-value shipments.


Our flagship product, a state-of-the-art container, integrates IoT sensors, e-ink displays, GPS / LTE-M connectivity, and access control. This combination offers companies complete visibility and control over shipments typically valued between €5,000 and €100,000. We serve industries such as luxury goods, art transportation, high-end e-commerce, and industrial/maintenance operations, where minimizing damage, theft, or loss is critical.


We are evolving our focus from “smart packaging” to an AI-powered logistics intelligence platform—transforming sensor and tracking data into predictive insights, automated anomaly detection, and proactive interventions.


Design is paramount to this evolution: we strive for interfaces that translate complex logistics into simple, human-centric, and reliable experiences.


What you will do


Discovery & problem framing

  • Plan and run product discovery with customers and internal teams (interviews, shadowing, workshops, UX research, and data analysis) to deeply understand:

    • how they ship and track high-value goods

    • their risks, fears, and “jobs to be done”

  • Translate fuzzy problems into clear problem statements, hypotheses, and user journeys.

  • Turn operational realities (logistics constraints, regulations, insurance, security) into concrete UX requirements.

Experience & interface design

  • Design end-to-end flows for:

    • Customer portal (track-and-trace, shipment management, alerts, analytics)

    • Hardware-adjacent UX (e-ink display states, mobile interactions around the product, handover UX)

  • Create wireframes, prototypes, and high-fidelity UI in Figma that are ready for implementation.

  • Use modern AI prototyping tools (Claude Code, Google Stitch, Paper, v0, Lovable, etc.) for rapid prototyping and exploration, then refine with strong design judgment.

  • Work with and evolve our design system (components, tokens, patterns) to keep experiences consistent across apps.

Collaboration & delivery

  • Partner closely with Product Managers, Engineers, Operations & Logistics to scope work realistically and ship iteratively.

  • Facilitate design reviews, co-creation workshops, and usability tests, turning feedback into clear next steps.

  • Document your thinking (flows, rationale, edge cases) so engineering and stakeholders can follow and contribute.

  • Support implementation with specs, design QA, and rapid iterations once things hit staging/production.

Data & continuous improvement

  • Help us evolve from “feature shipping” to hypothesis-driven, experiment-driven product work.

  • Collaborate with Product & Data to define UX success metrics.

  • Use both quantitative data and qualitative feedback to refine flows and reduce friction across journeys.


Who you are

  • Fluent in written and spoken English (French or German is a plus, but not required).

  • 5+ years as a Product Designer / UX/UI Designer in cross-functional product teams.

  • Unmatched sense of visual craft and art direction.

  • Strong track record in B2B / complex systems (logistics, fintech, SaaS, operations, industrial, or similar).

  • Demonstrated experience in end-to-end discovery

  • A Figma power-user

  • Comfortable working with modern AI & prototyping tools (e.g., Claude Code, Google Stitch, Paper, v0, Lovable, Framer, code-assisted prototyping) and keen to integrate them into your daily workflow.

  • Able to simplify complex information (sensor data, shipment events, risk signals, analytics) into clear, human-friendly interfaces.

  • Excellent communication skills — you can present work to leadership, explain trade-offs, and listen carefully to operational realities.

  • A system thinker: you see how a small UI change affects operations, data, and the physical world around our products

  • A bias toward action: you’re comfortable shipping iteratively instead of waiting for “perfect.”


Nice to have

  • Hardware/IoT or hardware–software product experience (e.g., working with devices, sensors, or embedded screens).

  • Experience in logistics, supply chain, transport, or high-value goods.

  • Experience in an environment shifting from hardware to platform / data business models.

  • Experience mentoring others, elevating design quality through feedback, and helping improve team rituals and ways of working.


What we offer 

  • Impactful problems: help redefine how high-value goods move around the world — with real sustainability and security impact.

  • Strategic seat at the table: work directly with the Head of Product, CMO, and Founder, influencing product and brand direction.

  • Remote+ work: flexibility to work remotely in Poland with occasional on-site sessions in France for workshops and team time.

  • Competitive B2B compensation.

  • A culture that values experimentation, learning, and ownership.


How to apply 


Send us your portfolio with a few case studies that clearly show both:

  1. your discovery process (how you found the right problem and shaped the solution), and

  2. work that shipped to production (how you collaborated, made trade-offs, and delivered outcomes).

Based on the portfolio review, we’ll contact selected candidates with the next steps.
