Mid-Term Ux/Ui Designer, Mobile

Wise Pirates seeks restless people, focused on evolving to learn, on producing meaningful impacts, and on working in a highly collaborative way, in a Digital and Tech context.
We want to meet people who are digital natives and full of good energy and a good attitude.
This is design with a number attached.
Most of what our clients sell happens on a phone, and most of what goes wrong there is not taste: it is a form that asks too much, a checkout that forces an account, a page that takes four seconds to become useful.
You will design the thing, and then find out whether it worked.
The work runs from research through to build-ready files, alongside front-end, analytics and CRO people rather than in a separate design phase.
Nobody here is asked to produce a beautiful screen that nobody can implement or measure.
What has changed in this discipline is where the designer sits.
Experience stopped being a layer on top of a business and became one of the ways a business competes, which means the useful designer is the one who can read behavioural data, hold a conversation about revenue and retention, and connect a design decision to the number it is supposed to move.
You do not need to arrive as an analyst.
You do need to be at ease with evidence, and with being told the evidence disagrees with you.
Like everyone here, you will be judged on the marginal value you add to the company and to the projects you touch.
Key Responsibilities
Discovery & Research:
Understand the problem before designing for it: user research, usability testing, session and review analysis, and the judgement to tell a real pattern from a loud opinion.
UX Design:
Flows, information architecture and interaction design for websites, e-commerce and web apps, mobile first by default rather than as an adaptation.
UI Design:
Interfaces that are clear, fast and on brand, made to be built rather than admired in a presentation.
Design Systems:
Build and maintain component libraries and design tokens, so a second designer or a developer can carry the work without inventing their own version of it.
Conversion Design:
Work on the friction that costs money: forms, guest checkout, validation, empty states, error handling, the first screen.
Accessibility:
Design to WCAG 2.1 AA and to the European Accessibility Act, treating it as part of the brief rather than a late audit.
Developer Handoff:
Deliver specs, states and edge cases that a developer does not have to guess at, and stay available while it is built.
Measurement:
See how a design performed once live, and let that change the next one.
Collaboration:
Work with front-end, analytics, CRO and content from the brief onwards, and present your own decisions to clients with the reasoning behind them.
Technical & Platform Skills
Experience:
2 to 4 years designing digital products or commercial websites, in an agency, in-house or freelance with real clients.
Portfolio:
A portfolio we can go through, showing the reasoning and not only the final screens.
Design tooling:
Fluency in Figma, including components, variables and prototyping.
UX craft:
Comfort with flows, wireframes, information architecture and usability testing, and with designing for small screens first.
Interface craft:
A solid eye for typography, spacing, hierarchy and state, and the discipline to keep a system consistent.
Web literacy:
Enough understanding of HTML, CSS and how the web actually renders to design things that can be built and that load quickly.
AI literacy:
Literacy in Tech and AI subjects, and sophisticated use of AI platforms in the design process, both with efficiency and security: research synthesis, variant generation and prototyping, with the judgement to treat the output as a draft rather than an answer.
Languages:
Fluent Portuguese and solid English.
Behavioral Skills
Kindness:
At Wise Pirates we promote and admire kindness, independently of rhythm, intensity and efficiency.
Curiosity:
You want to understand why something behaves the way it does, and you keep asking after the first answer.
Ownership:
Accountability for what you deliver and for what you promise a client.
Collaborative Spirit:
Proactive in working across multi-disciplinary teams, sharing knowledge rather than holding it.
Analytical Mindset:
Capable of putting data first and obsessed with insight building, always with client satisfaction and business results in mind.
AI Readiness:
Interest and fluency in using AI as a partner to deliver efficient value, respecting security and privacy regulations.
Results-Oriented Zeal:
An unwavering commitment to the client's bottom line, pushing boundaries to chase the best overall performance and business goals.
