Senior Software Engineer
Company description
At PandaDoc, we're building the future of documents.Our platform helps teams create, send, track, and e-sign proposals, contracts, and other documents, making our clients' lives more efficient and collaborative.
We’re a fast-growing company with a global reach. Our product is used by people around the world, from small businesses to large enterprises. In 2024, we reached a major milestone: over $100 million in annual recurring revenue! We're constantly innovating and releasing new features to meet the evolving needs of our customers, all while focusing on stability, quality, and performance.
Our Engineering team is a diverse and talented group of around 250 individuals, passionate about building a world-class product. While this is a fully remote position, we'd love for you to visit our vibrant offices in Warsaw, Lisbon, or Kyiv whenever you'd like to connect with colleagues in person.
About the role
PandaDoc is seeking a Senior Software Engineer to join our Core UX Platform team, part of the Core UX area within our Application Platform track. 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. This is infrastructure work — you'll drive large-scale migrations, publish versioned packages, and own the developer experience of your consumers across the organization.
About Core UX
Core UX is the foundational area for PandaDoc's frontend experience. We focus on building platform frameworks, intelligent tooling, and architectural foundations that enable product teams to move faster and build better. The Core UX Platform team specifically focuses on:
Building and evolving the application framework, platform tooling, and architectural foundations that product teams depend on
Decomposing legacy monolithic codebases into modular, scalable microfrontend architecture using Module Federation
Providing versioned platform libraries consumed by 70+ product repositories across the organization
Driving developer experience, performance, stability, testing, and maintainability improvements
Leading modernization initiatives across the frontend ecosystem — React upgrades, build tooling migration, shared infrastructure
The platform consists of:
Core application shell and bootstrap infrastructure
Shared platform libraries and utilities
Microfrontend framework — transport layer, module federation loaders, and runtime
Build and developer tooling
What you'll achieve
Development
Build and maintain Application Platform frameworks that standardize how product teams build, integrate, and ship frontend features
Drive large-scale migrations and codemods across the codebase — React upgrades, build system modernization, API changes — often spanning multiple repositories
Design and publish versioned platform libraries and developer tools with real downstream impact — changes you make propagate across the product ecosystem
Ensure production-grade quality through comprehensive testing, performance instrumentation, and disciplined versioning and breaking-change management
Cross-functional execution
Collaborate with Product, Platform, and Infrastructure teams to ensure a consistent, reliable, and high-performing application architecture
Partner closely with Design Systems, Backend Platform, and DevOps to align on shared foundations and platform evolution
Coordinate rollout strategies for platform changes that affect multiple consuming teams — migrations require communication, tooling, and patience
Evangelism
Drive adoption of platform standards and patterns across the organization by supporting engineering teams, improving documentation, and establishing clear migration guides
Champion engineering best practices around build tooling, testing strategies, and frontend architecture
Support product teams in adopting new platform capabilities — module federation, transport APIs, shared runtime modules
Innovation
Stay ahead of industry trends in frontend infrastructure, build systems, and developer tooling
Leverage GenAI to accelerate platform work — build intelligent agents, migration tools, codemods, and automation that help engineers work more efficiently
Continuously push the stack forward — modernize React to the latest version, evolve build tooling, and improve developer experience across the ecosystem
Our stack
JavaScript/TypeScript
Event Sourcing
React
Redux
Redux-saga
Styled-components
Webpack
Jest/testing-library, playwright
About you
Frontend infrastructure and build systems: Deep expertise in TypeScript, React, and modern build tooling (Webpack, Rspack, or similar bundlers)
Platform team experience: 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.
Library authorship: 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
Large-scale migrations: 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
Microfrontend architecture: Familiarity with Module Federation, modularization patterns, or large-scale frontend architectures
Testing and quality: Comfortable with testing strategies across the stack (unit, integration, e2e) and performance instrumentation
Communication and influence: Ability to coordinate platform changes across consuming teams, write clear migration guides, and collaborate effectively with engineers across the organization
AI fluency: Willingness to leverage AI tools in your workflow — from code generation to migration automation — and explore how AI can enhance developer experience
What makes you successful
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
Nice to have
Experience with pnpm workspaces, Nx, or monorepo tooling at scale
Background with Biome, SWC, or modern JavaScript toolchain evolution
Contributions to open-source frontend infrastructure or build tools
Experience leveraging AI tools to accelerate migration and platform work
