About the role
You’ll design the end-to-end experience for Simetrik’s new Developer Portal (devsite): the place where engineers discover our APIs, understand integration paths, and get from “hello world” to production. This is a UX role for someone who can think like a developer: mapping technical journeys, shaping information architecture, and prototyping flows that make complex integrations feel simple. You’ll work side-by-side with Product and Engineering, iterating quickly with real developer feedback and shipping designs that are implementation-ready.
What does success look like in this role?
- Developers can self-serve: they understand our APIs, auth, and integration steps without hand-holding, and complete key tasks end-to-end.
- Ambiguity gets turned into testable prototypes and then into production UI/UX, with measurable improvements to time-to-first-call and integration success.
- The devsite’s information architecture, navigation, and patterns are coherent, reusable, and accelerate delivery across squads.
- Collaboration with Engineering is tight and pragmatic; trade-offs are explicit; pace and craft both go up.
What is the impact and scope of this position?
- Direct impact on Simetrik’s Developer Platform/DevTools surface—the entry point for partners and customers integrating with our products.
- Ownership from discovery to delivery across multi-state, data-heavy, technically nuanced surfaces (docs, guides, API references, quickstarts, troubleshooting).
- Foundation for future AI-assisted experiences (e.g., guided setup, explainers, code walkthroughs) through clear patterns and component architecture.
What outcomes are expected in the first 3 to 6 months?
- Produce and test interactive prototypes with internal/proxy developers; incorporate feedback from at least 3+ engineers across squads.
- Define IA, content models, and page templates for core surfaces (Overview, Auth, Guides, API Reference, Errors, Changelog, SDKs) with full state coverage (loading/empty/error/recovery).
- Contribute 2+ reusable patterns/components (e.g., code blocks with language tabs, step indicators, inline callouts) with usage guidelines engineers can implement quickly.
- Establish fast rituals with Engineering (design-dev working sessions, “show-me-the-Figma/code” reviews) to ensure feasibility, consistency, and performance.
In this role you will
- Map developer journeys from discovery to first successful API call and production readiness.
- Design flows, IA, and UI for docs, guides, quickstarts, and API reference that reduce cognitive load and decision friction.
- Prototype rapidly (Figma or no-code in our platform) to validate assumptions with real developers.
- Partner daily with engineers to co-evolve patterns, remove blockers, and keep design/dev in lockstep.
- Write lightweight specifications and usage notes that make reuse obvious and reduce back-and-forth.
- Measure outcomes (e.g., time-to-first-call, error rates, drop-offs) and iterate toward clear targets.
What are the key responsibilities of this role?
- Own the devsite experience end-to-end: problem framing, IA, flows, states, and high-fidelity UI.
- Define componentized, token-driven patterns for developer content (tabs, accordions, code fences, versioning, deprecation notices).
- Ensure multi-state coverage (empty/loading/error/retry) and robust edge-case handling in all designs.
- Collaborate on a pragmatic “design system for docs” usable by multiple squads; document do’s/don’ts.
- Translate technical concepts (auth, webhooks, pagination, rate limits, errors) into clear, navigable structures.
- Run quick usability checks with engineers; synthesize findings into concrete design changes.
- Contribute to a high-ownership, outcome-oriented culture—clear decisions, fast iterations, crisp handoffs.
Must Have
- Proven experience shipping UX for developer-facing products (dev portals, API docs, SDK guides, or technical tooling) not just marketing pages.
- Figma mastery: components/variants/properties, libraries, auto-layout, and prototyping.
- Technical empathy: you’ve built simple projects or scripts (any language) and can speak credibly about API basics (auth, requests/responses, errors).
- Information architecture strength for complex content: you structure docs so devs find the right artifact at the right moment.
- Systems thinking applied to patterns and reuse across multiple surfaces and squads.
- Bias to action in ambiguous spaces; you prototype, test, and iterate quickly with engineers.
- Clear communication focused on trade-offs, constraints, and decisions.
Core skills and competencies required for success
- User-journey mapping for technical users; reducing integration friction.
- Multi-state design for data-rich, failure-aware experiences.
- Component architecture for consistency and speed.
- Rapid prototyping and lightweight usability testing with developers.
- Partnering with Engineering to ensure feasibility, performance, and accessibility.
- Outcome orientation: define metrics, instrument feedback loops, iterate.
Nice to Have
- Experience with API tooling (OpenAPI/Swagger), doc-as-code workflows, or frameworks like Docusaurus/Next.js (awareness is enough; coding expertise not required).
- Exposure to B2B fintech, data platforms, or integration/orchestration products.
- Designing for AI-assisted workflows (guided setup, explain/explore patterns).
- Comfort using no-code/low-code tools to demo flows in realistic contexts.
- Running quick research (surveys/interviews) with developers.
Qualifications
- 4+ years in Product Design or closely related discipline with shipped developer-facing work.
- Portfolio showing dev-oriented UX, strong IA, and componentized UI at production quality.
- Fluency in Figma; ability to create and document reusable patterns.
- Working proficiency in English and Spanish.
- Based in Colombia or Argentina (collaborating across time zones with distributed squads).
Benefits
- Well-funded and proven startup with large ambitions and competitive salaries.
- Entrepreneurial culture where pushing limits, creating and collaborating is everyday business.
- Open communication with management and company leadership.
- Small, dynamic teams = massive impact.
- 500USD a year for you to invest in learning.
