About the role
- Your work will directly shape the frontend infrastructure and application framework that 35+ product teams build on top of, impacting millions of users across the PandaDoc ecosystem.
- As a Senior Engineer on the Platform team, you'll build and maintain the frameworks and libraries that other engineering teams depend on to ship products.
- Drive large-scale migrations, publish versioned packages, and own the developer experience of your consumers across the organization.
- Build and evolve the application framework, platform tooling, and architectural foundations that product teams depend on.
- Decompose legacy monolithic codebases into modular, scalable microfrontend architecture using Module Federation.
- Provide versioned platform libraries consumed by 70+ product repositories across the organization.
- Drive developer experience, performance, stability, testing, and maintainability improvements.
- Lead modernization initiatives across the frontend ecosystem — React upgrades, build tooling migration, shared infrastructure.
Requirements
- 8+ years in software engineering with strong frontend and infrastructure expertise
- You've produced platform infrastructure — not just maintained a large application. You understand the difference between building features and building the foundations others build features on.
- Extreme ownership mindset — you drive platform initiatives from design through implementation to adoption across the organization
- Comfort working across both legacy and modern codebases — you can navigate older patterns while driving toward better ones
- You're comfortable in remote, distributed environments and communicate effectively across time zones.
- Deep expertise in TypeScript, React, and modern build tooling (Webpack, Rspack, or similar bundlers)
- Prior experience as a member of a frontend platform, infrastructure, or developer tools team — this is not an application feature team. You should have built and shipped tooling, frameworks, or libraries that other engineering teams depend on to do their work.
- Experience authoring and publishing packages consumed by multiple teams — not just contributing to a shared codebase, but owning a product (libraries, SDKs, developer tools) whose consumers are other engineers.
- Hands-on experience executing application-wide or multi-repo codemods, framework upgrades, or foundational API changes — you understand the coordination, tooling, and rollout strategies that make them succeed.
- Familiarity with Module Federation, modularization patterns, or large-scale frontend architectures.
- Comfortable with testing strategies across the stack (unit, integration, e2e) and performance instrumentation.
- Ability to coordinate platform changes across consuming teams, write clear migration guides, and collaborate effectively with engineers across the organization.
- Willingness to leverage AI tools in your workflow — from code generation to migration automation — and explore how AI can enhance developer experience.
Benefits
- Remote-first approach with the option for hybrid work from our offices in Kyiv, Warsaw, and Lisbon.
- We value long-term collaboration, whether through typical employment contract, employment of record or B2B arrangements. Be aware that contract type and benefits vary by location - feel free to clarify with our recruiters.
- Work schedule aligned with EU time zones.
- Honest, open culture that values constructive feedback.
- Professional and personal development within a collaborative, supportive team.
- Stable yet growing SaaS product offering an agile environment, ownership, start-up energy, and strong technical challenges.
