Job description

As stewards of the Polkadot and Substrate ecosystem, Parity is laying the foundation for a better web. We believe in a decentralised web that respects the freedom and data of individuals and empowers developers to create better services. Our vision is to create a world based on truthful, rather than trustful, interactions.

Parity is one of the world's most experienced core blockchain infrastructure companies, having built and pioneered some of the most advanced technologies in the blockchain sector.

With a remote-first, global team, Parity is building open-source technologies for developers and organisations to implement and build upon. Our Web3 tech stack includes Polkadot, Substrate, and Kusama.

People in our collective are:

• Highly motivated to contribute to Parity’s mission and be part of something bigger

• Excited to work on projects that are groundbreaking and complex

• Autonomous workers that self-initiate, but also collaborate well with others

• Taking maximum accountability and having minimum ego at work

• Comfortable with chaos and adapting to the ever-changing Web3 space

• Continuously educating themselves about Parity and the wider ecosystem

About the team

The DevEx team works across the entire Polkadot ecosystem to improve developer workflows, tooling, and documentation. We own the experience of developers—from first contact with a template, guide, or CLI, to advanced tooling used in production.

This is not a support role. You’ll build the tools you wish already existed. You’ll collaborate with core engineering, marketing, solutions, and the community. You’ll also attend hackathons, support builders, and help scale what’s possible in the ecosystem.

About the Position

• Design and implement CLI tools, templates, SDKs, and onboarding flows.

• Improve and maintain documentation and developer portals.

• Write code samples, example projects, integration demos (Rust, TypeScript, Solidity).

• Contribute to better CI/CD setups for devs building with Substrate and Polkadot SDK.

• Engage with developer teams, answer deep technical questions, gather feedback.

• Work cross-functionally with engineering and product teams.

• Participate in events and hackathons, acting as an ambassador for great DevEx.

About You

• 3+ years of experience in Rust, 2+ years in TypeScript.

• Solidity experience — you’ve built and deployed smart contracts using Foundry, Hardhat, or Remix.

• Comfortable working with Linux, Docker, and CI/CD pipelines.

• A solid understanding of blockchain development, especially Substrate or EVM-based ecosystems.

• Experience writing technical documentation, tutorials, or guides.

• Confidence to speak with external developers — on Discord, Matrix, or in person.

• A bias toward automation, quality, and clarity.

• Enthusiasm for open source, hackathons, and building things developers love.

Bonus points for

• Experience with smart contracts.

• Contributions to open-source developer tools or frameworks.

• Involvement in blockchain communities, hackathons, or meetups.

About working for us

• Competitive remuneration packages based on iterative market research, including tokens (where legally possible)

• “Future of work” environment that’s remote-first and self-initiating with flexible hours

• Teammates that are genuinely excited about their impact and projects

• Access to the brightest minds in this space to learn about Web3 and develop your skills and knowledge while on the job

• Becoming part of the wider ecosystem (career and networking opportunities)

• Team and company-wide retreats

• Work laptop

• Opportunity to relocate to Germany or Portugal (with visa sponsorship)

Those joining our collective as an employee in Germany, Portugal, Switzerland and the U.K. also enjoy benefits such as health care, parental leave, PTO (28 days per year), local team events, yearly L&D budget, and language classes.

Parity is an Equal Opportunity Employer. We welcome diversity in our global team and care about everyone in our collective feeling included and welcome.
