There are NO limits to your career: come shape the future and be part of a truly unique global culture at OutSystems!
Senior Front-End Developer | Professional Services
As a Senior Front-End Developer, you will be at the forefront of Agentic Workflow Orchestration. In this role, you aren't just building interfaces; you are designing the collaborative space where humans and AI agents interact. Your mission is to leverage OutSystems to build high-performance, accessible, and low-cognitive-load experiences that solve complex business problems.
The Mission: Agentic Excellence
Your work will focus on the North Star of Professional Services: Reducing User Cognitive Load. You’ll build UI patterns that make autonomous agent actions transparent, trustworthy, and seamless for the end-user.
Core Responsibilities
- Live Style Guide (LSG) Engineering: Build and maintain scalable LSGs and UI patterns. You won't just deliver a static library; you will build the "rules of engagement" that allow AI agents to correctly assemble customer-branded interfaces.
- Agentic Orchestration: Act as the supervisor of AI agents. You will prompt, audit, and orchestrate agents to generate code, troubleshoot UI bugs, and automate repetitive front-end tasks, ensuring the output delivers value to our customers.
- Prompt Engineering for UI: Develop and refine the system prompts used to generate OutSystems logic and UI. You are responsible for ensuring the AI understands the "governance" of the customer’s style guide.
- Technical Troubleshooting: Solve the "impossible" front-end bugs. Whether it’s a CSS race condition in a legacy app or a non-deterministic error in a new agentic workflow, you are the final point of escalation.
- Customer Workshops & Coaching: Lead workshops on Front-End best practices and Accessibility (WCAG). Transition customer teams from manual "pixel-pushing" to an "Orchestrator" mindset.
- Work directly with customers to troubleshoot challenging front-end issues and refine their front-end strategy.
- Mentor junior developers in the transition from traditional development to AI-assisted coding.
What We Look For
Advanced knowledge of HTML, CSS, and JavaScript.
Proven experience developing high-quality applications using the OutSystems platform (OutSystems UI & Mobile UI).
Ability to optimize applications for speed and search engine visibility.
Experience implementing and a strong commitment to accessibility (WCAG) and creating tools that work for everyone.
AI code fluency: Ability to read, debug, and optimize code generated by LLMs. You understand the "hallucination" patterns of AI-generated front-ends.
Advanced prompt engineering: Experience structuring multi-step prompts to achieve specific, high-quality technical outcomes.
Systemic thinking: You don't just fix a bug; you fix the prompt or the pattern so the bug never happens again.
Fluent in English (mandatory) with the ability to explain technical concepts to diverse audiences.
Ability to work effectively across different cultures and geographies in an agile environment.
A proactive attitude towards coaching other developers and contributing to the evolution of the Front-End practice.
Leadership by example, strong analytical thinking, and a focus on user-centric design.
5+ years of experience in OutSystems and experience in enterprise software development.
Certifications: OutSystems Expert Developer; Specialist Agentic AI certification preferred, Front-end Developer Specialist.
