Wallapop is a Barcelona based scale-up driven by the purpose to empower people to embrace a more conscious and human way of consumption. We believe in a world where collaborative economy is mainstream. This is what drives us. 💫

Wallapop operates in Spain, Italy and Portugal, offering a catalogue of several hundreds of millions of products and services. Powered by technical innovation and continuous improvement, we bring together the scale & trust of classifieds with the marketplace’s convenience & reach. 🌱 Our mission is to enable a connected trade ecosystem, making 2nd-hand the norm through smart use of technology.

The Challenge 🧩

Identify, frame, and shape a design roadmap aimed at enhancing our user experience and driving key business metrics. In this role, you will operate with a high degree of autonomy — you are not waiting for a roadmap to execute or a solution to be handed to you. You will bring a strong design and user perspective to product strategy: understand where the PM is headed, what the data shows, and what users need — then align, challenge, and shape the direction so that design thinking influences how problems are framed, not just how they're solved.

As a Senior Product Designer, you will play a pivotal role in shaping Wallapop's discovery journey — creating engaging, intuitive, and scalable user experiences. Your work will directly enhance how millions of users discover and connect with unique items. This role blends strategic vision with hands-on design execution: you will help define design strategies and frameworks while building seamless, multi-feature end-to-end flows with an elevated UI. By partnering with cross-functional teams, you will move Wallapop's product vision forward and ensure every initiative delivers measurable value for both our community and the business.

What You Will Do 👇

• Strategic partnership: Bring a strong point of view to product strategy. Challenge assumptions, ensure user and design thinking shapes how problems are framed, and actively seek input from analytics, data science, research, engineering, and content strategy to inform the direction. Contribute meaningfully to roadmap decisions and prioritization.

• Problem framing: Navigate ambiguity from the start. You'll often begin with an ill-defined problem space, scope and frame it, identify the right opportunity, and build a clear path forward before a solution even exists.

• Complex, multi-feature design: Lead end-to-end experiences spanning multiple features, and touchpoints. You’ll work with interconnected systems where a change in one area ripples across others, not isolated flows or single-feature work.

• End-to-end execution: Own the design process from early discovery through to high-fidelity UI and technical specs. Testing, iterating, and building stakeholder alignment along the way to ensure proposals are feasible, desirable, and ready to ship.

• Evidence-based design: Translate quantitative data and qualitative insights into elegant, actionable design solutions that solve real human problems and drive measurable impact.

• Elevated craft: Champion visual excellence and push the boundaries of our current UI,  delivering intentional, delightful experiences that raise the bar across the product.

• Consistency & scale: Contribute to our global design system, ensuring a seamless and accessible experience across all platforms.

• Mentorship & culture: Act as a thought partner for fellow designers, fostering a culture of mutual growth, confidence, and design excellence.

What We’re Looking For 🔎

• Seniority: We are looking for a very senior profile , someone who has already operated at this level, not someone growing into it. Ideally with 8–10 years of product design experience, with 5+ years operating at a senior or lead level. Setting direction, working independently, and influencing product decisions beyond the design brief.

• Product experience: Deep experience designing mobile-first digital products at scale, such as marketplaces, e-commerce, or similarly complex consumer applications.

• Strategic thinking: A natural ability to bring a design and user perspective into product strategy,  not just executing a vision, but helping shape one. Comfortable pushing back on assumptions and advocating for the right problem to solve.

• Complexity & systems thinking: Proven experience leading multi-feature, end-to-end experiences with systemic complexity that involve dependencies, and require thinking across the full user journey.

• Problem framing: Comfortable starting from ambiguity, scoping ill-defined problems, forming hypotheses, and iterating toward clarity before jumping to solutions.

• Visual craft: A high bar for execution and a natural ability to deliver intentional UI that balances aesthetic beauty with functional clarity, even within strict system constraints.

• Design tooling: High proficiency in Figma and modern prototyping workflows, with an interest in staying current with industry best practices.

• Collaboration & communication: Able to articulate the why behind design decisions and build alignment across functions by partnering with analytics, data science, research, engineering, and content strategy to pressure-test direction and drive decisions forward with confidence.

What Would Be A Plus 🚀

• Experience working within a fast-paced, iterative product-tech company.
• A background in graphic design, visual design.
• Experience or interest in accessibility standards (WCAG) to ensure our platform is inclusive for everyone.

Do note that all our jobs are 📍 Barcelona based. We follow a hybrid model where flexibility rules. We commit to a minimum of 6 days per month in the office. Each team self-organizes to decide on cadence and in-person/remote rituals.

WHO WE ARE 🌍

We help creators get more out of every conversation with Instagram-focused automations and support for other channels like Messenger, WhatsApp, and TikTok. The result? Better engagement, more sales, and real, sustainable growth.

With a diverse team of 350+ people spread across three continents, we’re building the leading Chat Marketing platform that is used — and loved — by more than 1.5 million customers worldwide.

WHO WE'RE LOOKING FOR 🌟

The AI era isn't coming, it's already here. At Manychat, we're building it into the foundation of everything  and we need an Applied AI Engineer to help make that real.

Your main focus will be AI agents and agentic workflows, LLM-powered system orchestration, and automation pipelines that integrate into the business processes that actually matter. You'll work across internal and customer-facing systems, writing production-grade code and partnering with product and business teams to turn complex challenges into reliable, scalable solutions.

We'd love to work with someone who brings more than strong engineering fundamentals. Someone with the product mindset to understand business context, the communication skills to work fluidly across teams, and the pragmatism to choose solutions that are effective and built to last. Ownership matters here: we're looking for someone who drives work from discovery to rollout, not someone who hands things off at the first checkpoint.

If success for you means identifying real AI use cases, building things that work reliably at scale, and being a trusted technical partner to the teams around you, let’s talk! 

WHAT YOU'LL DO 🚀

• Design, build, and maintain AI-driven services and agent-based solutions for workflow and business process automation.

• Ability to understand business workflows and translate ambiguous requirements into clear technical solutions.
• Experience collaborating with product teams, analysts, operations, and other stakeholders.
• Strong communication skills and the ability to explain complex solutions to both technical and non-technical audiences.

IT WOULD BE GREAT IF YOU HAVE 🤩

• Experience with LangChain, LangGraph, OpenAI SDK, LlamaIndex, or similar frameworks.

• Champion work-life harmony. We’ll give you the flexibility you need in your work life (e.g., flexible vacation time above any required statutory leave, company-wide holidays and timeout (meeting-free) days, remote work options and more) so you can enjoy your personal life too.
• Guarantee autonomy. We have an open, honest culture and we trust our people from day one. Your team will support you, but you’ll own your work and have the agency to try new ideas.
• Encourage career growth. We’re lifelong learners who encourage professional development. We’ll give you tons of resources and opportunities to keep growing.
• Provide an environment to help you succeed. We've invested in our offices, designing incredible spaces with our employees in mind. But whether you’re at the office or working remotely, we’ll provide you the tech you need to do your best work.
• Support your wellbeing. Depending on location, we offer medical and retirement benefits for employees—but no matter where you’re located, we have resources like our Employee Assistance Program and employee resource groups to support your mental health.

Compensation

We make compensation decisions based on an individual's experience, skills and education in line with our internal pay equity practices. 

This role will also be eligible for a long-term incentive (LTI) award. Any bonuses awarded are based on individual and company performance paid at Hudl's discretion. 

Your Role

We’re hiring Senior Engineers to join one of our cross-functional product teams in our Human Performance group, which is focused on building cutting-edge solutions for athletes and sports teams that directly impact how they train, compete and achieve peak performance.

As a Senior Engineer, you’ll:

• Work with a cross-functional team. You’ll collaborate with Engineering, Quality Assurance, Product, Design and Scrum disciplines to deliver full-stack web features. 
• Develop and deliver. Your team has the autonomy to make a meaningful impact across the entire product area, listen to customers' needs and deliver game-changing features to push the boundaries of what they can achieve. Your team is empowered to take ownership of the user experience to support our coaches and athletes.
• Test new ideas. At Hudl, we iterate rapidly, deploying changes to the product hundreds of times daily across our Engineering team. In addition to working on concrete features, you’ll have the opportunity to propose solutions to more ambiguous technical problems and provide guidance to less experienced engineers.
• Mentor. You’ll share your expertise and educate others on development best practices and trade-offs, setting an example in planning, designing and delivering complex projects. 

For this role, we're currently considering candidates who live within a commuting distance of our offices in London. But with our flexible work policy, there aren't any current requirements for the number of days you come to the office.

Must-Haves

• Experienced. You have either led or played a key role in developing large-scale applications.
• A team player. You understand that problem-solving is a team effort and will help others on our Engineering team learn and develop their skills.
• User-focused. You’re excited to have your work used by real people to solve real problems.
• Willing to learn. You have solid engineering skills but are always willing to dive into specific areas to gain the expertise needed to be successful in your role.
