Product Design Engineer
Oneiro Solutions and its Digital Loan Exchange (DLX) platform brings to market an entirely digital syndicated loan administration platform. Built on modern technology standards, DLX removes the need for faxes and emails, giving borrowers, lenders and agents a more seamless, collaborative and transparent experience throughout the lifecycle of a syndicated loan.
We are looking for a Product Design Engineer, someone who is as comfortable thinking through user journeys, workflows and interaction patterns as they are building high-quality frontend applications.
This is a hybrid product-design and engineering role. You will help shape how complex financial workflows are translated into clear, intuitive and reliable web application experiences. You will work closely with product, backend engineering and domain experts to understand user needs, design practical solutions, prototype ideas, and implement polished interfaces in the DLX platform.
This role would suit someone who enjoys the craft of frontend engineering, but also has a strong voice in product experience, usability and design.
Role description
As a Product Design Engineer you will work on complex enterprise workflows where clarity, trust, accuracy and usability matter. You will be responsible for designing, prototyping and building user-experiences for the DLX web application.
You do not need to be a pure Product Designer, but you should care deeply about how users interact with software. You should be able to think through flows, states, edge cases, information hierarchy, accessibility and interaction details, bringing bring those ideas to life in production code.
The ideal candidate will be able to learn new technologies and business domains quickly, work with autonomy, collaborate openly, and adapt in a fast-moving startup environment. At Oneiro, you will have space to raise ideas, challenge assumptions and help shape the product experience as we build a new category of digital loan administration software.
Responsibilities
- Design, prototype and build user interfaces for the DLX web application.
- Translate complex syndicated loan workflows into clear, usable and elegant product experiences.
- Work closely with product stakeholders, engineers and non-technical domain experts to understand user problems and shape practical solutions.
- Create wireframes, interaction flows, prototypes or design explorations where useful.
- Implement high-quality frontend features using Vue.js and modern web technologies.
- Contribute to the evolution of our design system, component library and UI patterns.
- Think through empty states, error states, loading states, validation, accessibility and responsive behaviour.
- Ensure the technical feasibility of product and UX ideas, balancing user needs, business needs and engineering constraints.
- Write clean, reusable and efficient frontend code following best practices.
- Optimise web applications for performance, scalability and maintainability.
- Participate in code reviews and help improve engineering and design standards.
- Use feedback, product context and user insight to iterate on features after release.
- Stay up to date with emerging trends in frontend development, product design and enterprise UX.
Requirements
- 2–5 years of experience in frontend engineering, product engineering, UX engineering, product design engineering, or a similar hybrid role.
- Strong frontend development skills with Vue.js, or another modern reactive JavaScript framework.
- Excellent knowledge of HTML, CSS and JavaScript, preferably ES6+.
- Good product design judgement, with the ability to reason about user flows, interaction patterns, hierarchy and usability.
- Experience working with design tools such as Figma, Sketch or similar.
- Ability to prototype ideas quickly, either in design tools or directly in code.
- Understanding of REST APIs or GraphQL.
- Strong problem-solving skills and attention to detail.
- Ability to work through ambiguity and simplify complex workflows.
- A principled but pragmatic approach to software engineering and product design.
Desirables
- Experience in B2B SaaS, enterprise software, fintech, banking, corporate banking or investment banking.
- Experience designing or building complex workflow-heavy applications.
- Experience with TypeScript.
- Experience with testing frameworks; we currently use Playwright.
- Experience contributing to design systems or component libraries.
- Familiarity with accessibility standards and inclusive design principles.
- Experience conducting or participating in usability testing, user interviews or product discovery.
- Ability to write clear UX copy, labels, tooltips or product microcopy.
What we are looking for
We are especially interested in people who can:
- Think like a product designer and build like a frontend engineer.
- Care about both the user experience and the quality of the implementation.
- Take a complex process and make it feel simpler.
- Spot UX gaps before they become engineering problems.
- Work autonomously while collaborating closely with the wider team.
- Balance polish, speed and pragmatism in a startup environment.
- Bring ideas, challenge assumptions and help improve how we design and build.
