Jobs Spain

Headway Inc is a global tech company, revolutionizing lifelong learning by creating digital products for over 170 million users worldwide. Our mission is to help people grow. We’re proud to be ranked 4th among the World’s Top EdTech Сompanies by TIME magazine. We believe lifelong learning should be accessible, personalized, and impactful to each individual. That’s how we change the world and why we bring together exceptional minds.

The core of our achievements is our team. We believe in people and shared values SELECT. That’s why, together with Oleksandra Khilienko, Head of Globalization at Headway Inc, we're looking for a Globalization Product Manager to make sure every product we ship feels like it was built for the market it lands in.

The team you'll be working with

This is a role that touches almost everything we ship globally. You'll sit at the intersection of product management, user research, and linguistic strategy – working across product, design, and user experience, alongside a Growth Globalization Manager and native-language reviewers who keep our products feeling local. Your decisions will shape how millions of users interact with our products across very different languages, cultures, and markets.

You won't be starting from a blank page. There's a north star, a roadmap, real infrastructure, strong relationships with product teams and linguistic experts, and hard-won market knowledge. Your job is to run with all of that – investigate, form sharp hypotheses, and make the system meaningfully better where it counts.

This role is your calling if you

• Think in systems but act with precision – holding a multi-market picture in your head while staying focused on what actually ships.
• Are genuinely curious about how people in different cultures think, click, and decide and read nuance without defaulting to assumptions.
• Are as comfortable in a data dashboard as in a conversation with a reviewer about translation tone.
• Make sound calls with incomplete information, then iterate fast – ambiguity energizes you.
• Balance linguistic quality with business reality – you know when to trade polish for speed.
• Get global work prioritized by teams you don't manage, through credibility rather than a title.
• Move fluidly between strategy and operations, and improve things proportionately – fixing what's actually broken and leaving what works.

• Believe great globalization is invisible – every market should feel the product was made for them.

   

What you'll do

• Drive the globalization roadmap and push it upstream, so it's taken into account from the start, not bolted on.
• Turn market and user research into clear recommendations – what to commission, change, or localize – and partner with product teams and GMs who make the final call.
• Make our products feel native in every market, including the genuinely complex ones, and grow original, locally-authored content.
• Turn global behavioral data into real product and localization decisions and own the analytics that show they landed.
• Set the bar for UX localization and linguistic quality across teams you don't manage.
• Strengthen the systems behind it: AI-assisted translation pipelines, vendor and reviewer programs, and the tooling that keeps globalization fast and reliable.

• Experiment with AI as a core part of the job – spot the right use cases, weigh quality and brand risk, and evolve workflows as the technology does.

   

Who you might be

We're open to two kinds of backgrounds:

• The globalization expert who already thinks and acts like a product person – you know the craft (workflows, linguistic quality, experts, vendors, tools) and have the knowledge (analytics, user research, product lifecycle management) to move beyond service delivery into product contribution.

• The product manager ready to go deep on globalization – strong product judgment and analytical instincts, genuine curiosity about cultures and international users, and happy to roll up your sleeves for the operational side.

   

Either way, we're looking for one combination: product judgment + a quality mindset + business acumen + globalization potential + AI fluency.

What do we offer:

• Work within an ambitious team on a socially impactful education product.
• Access to our corporate knowledge base and professional communities.
• Personal development plan.
• Compensation for English language learning, external training, and courses.
• Medical insurance and full sick leave compensation.
• Sports activities: running, yoga, boxing, and more.
• We provide 20 paid vacation days per year. On top of that, we add 10 corporate holidays days to your balance – giving you 30 paid days off in total to rest.

• Supporting initiatives that help Ukraine. Find out more about our projects here.

   

Location

Remote, our Kyiv office, or our Madrid office – with Madrid being our preference for this role.

We are looking for a Team Lead who will take technical ownership of our web platform, a Laravel backend with a Vue.js frontend, and lead a small team of full-stack engineers. You will own the full delivery cycle and make critical architectural decisions across the stack, but your strongest impact will be on the frontend: building polished, intuitive interfaces, improving user flows, and raising the bar on UX quality without waiting for a dedicated designer. You will partner closely with Product to shape what gets built, establish engineering standards, mentor developers, and drive the platform forward through thoughtful refactoring, performance optimization, and incremental modernization of legacy code. This is a high-impact role with cross-team collaboration, fast decision-making, and an AI-first approach to development.
 

Requirements

• 5+ years of full-stack web development experience with a strong frontend focus.
• Expert-level Vue.js 3 skills: Composition API, Pinia, Vue Router, component architecture, and TypeScript.
• Strong eye for UI/UX: ability to critique user flows, spot friction, and ship improvements independently without relying on a designer for every decision.
• Solid Laravel experience: routing, Eloquent, queues, middleware, service providers, testing with PHPUnit/Pest.
• Experience leading a team (2+ people): code reviews, task planning, growing engineers, establishing standards.
• Good understanding of relational database design and PostgreSQL: schema design, migrations, query optimization.
• Experience with REST API design: versioning, error handling, authentication (JWT/OAuth), pagination.
• Product-minded: able to partner with a PM to translate business goals into well-considered interface and architectural decisions, and push back when something doesn't serve the user.
• Familiarity with Docker and CI/CD pipelines.
• Strong affinity for and understanding of how AI tools can aid yourself and the team in development.

Nice to Have

• Experience building or maintaining a design system or component library.
• Proficiency with Figma or similar design tools.
• Experience with GCP or comparable cloud (AWS/Azure) at the service level.
• Knowledge of Vite build tooling, SSR, or micro-frontend patterns.
• Experience with real-time features (WebSockets, broadcasting).
• Familiarity with Pulumi / Terraform for IaC.
• Understanding of healthcare / pharma ad-tech domain.
• Experience with Playwright or Cypress for E2E testing.

Responsibilities

• Own the technical direction of the web platform across frontend and backend, with particular depth on the frontend.
• Lead a team of 2-3 full-stack engineers: code reviews, sprint planning, mentorship, and career development.
• Drive feature delivery end-to-end: from database schema and API design to Vue.js components and user experience.
• Make independent UI/UX decisions day-to-day: improve flows, refine interactions, and raise interface quality without waiting for designer input. Consult with the design resource when needed for larger initiatives.
• Partner with Product to shape requirements, challenge assumptions, and advocate for the user in technical and design decisions.
• Identify and propose refactors based on expertise: recognize when code, architecture, or UX patterns need to evolve and drive those changes.
• Ensure code quality, test coverage, and maintainability across the full stack.
• Design and evolve the REST API layer: versioning, authentication, rate limiting, and documentation.
• Optimize application performance: query tuning, caching strategies, frontend bundle optimization.
• Manage technical debt and drive incremental modernization of legacy code.

What We Offer

• Fully remote with flexible hours (aligned with EU timezones for syncs).
• Influence on the quality assurance strategy across the entire engineering department.
• A cross-team role with visibility into every part of the product.
• AI-first tooling.
• Claude Code licenses and cutting-edge AI development workflows.
• A team with no bureaucracy, decisions are made fast.

Job Description

- 2–4 years of experience in GUI/UI test automation (any platform).
- Practical Swift skills — comfortable reading and writing production Swift code.
- Experience with XCUITest / XCTest on macOS or iOS, including the Page Object pattern.
- Working knowledge of SwiftUI — accessibility identifiers, view hierarchy basics, async state.
- Day-to-day use of Xcode and xcodebuild, test plans (.xctestplan), schemes.
- Git fluency — branching, rebasing, resolving conflicts, disciplined PR workflow, good commit hygiene, comfortable reviewing and being reviewed.
- JIRA (or equivalent issue tracker) — creating well-scoped tickets, linking PRs, writing reproductions, keeping statuses current.
- Jenkins CI/CD hands-on experience — reading and modifying Jenkinsfiles, triaging red builds, understanding declarative pipelines, stages, artifacts, and agents.
- Conda / virtual environment fluency — creating and activating envs, resolving dependency conflicts, understanding how PYTHONPATH, Poetry, and pyproject.toml interact. Awareness that
breaking an env breaks the whole pipeline.
- A systems mindset: understands that a passing local test is not a passing PR, and that coding practices (imports, globals, shared state, flaky waits, dependency bumps) can cascade
into CI and team-wide breakage.
- Debugging mindset for async / flaky UI tests — waits, expectations, race conditions.
- Professional English, written and spoken — the team operates in English and most collaborators are in PST.
- Willingness to overlap ~3–4 hours daily with PST

Job Responsibilities

- Write and maintain XCUITest automation using the existing Page Object structure.
- Add coverage for new features and user flows as the apps evolve.
- Investigate and fix flaky tests; reproduce, triage, and root-cause failures.
- Own your changes through CI — debug Jenkinsfile stages, read pipeline logs, understand how your test affects downstream jobs (build, publish, acceptance).
- Keep Conda / Poetry / npm environments healthy in the repos you touch; avoid dependency drift and lockfile breakage.
- Track work, bugs, and flaky-test investigations in the team's issue tracker (JIRA or equivalent) with clear reproduction steps and logs.
- Collaborate async with PST-based developers via Git code reviews, written specs, and written updates.
- Contribute improvements to the test framework (helpers, utilities, reporting) under guidance from senior engineers.

• Write and tune complex T-SQL queries, stored procedures, and views; troubleshoot performance bottlenecks.
• Establish and enforce data quality, validation, and reconciliation processes across the warehouse.
• Collaborate closely with Product Owners, Business Analysts, and backend engineers to translate business requirements into data models and pipelines.
• Document data flows, schemas, and transformation logic to support maintainability and onboarding.
