Job description

About the role

This role is focused on our developer platform for the Startale Wallet SDK. You will own the product experience for developers integrating our wallet — whether they are individual dApps connecting via our SDK or Miniapps that run inside the wallet. Reporting to the Head of Product, you will drive the roadmap, developer experience, and adoption of our SDK and related APIs. This is an individual contributor role with high visibility and impact.

Key responsibilities

• SDK product vision & strategy: Define the vision and strategy for the Wallet SDK and developer platform, aligned with company objectives and market needs.
• Roadmap ownership: Prioritize and deliver SDK features, APIs, and tooling that improve integration, reliability, and developer productivity.
• Developer experience (DX): Champion first-class DX across docs, samples, quickstarts, error messages, versioning, and migration guides.
• Execution & delivery: Lead end-to-end delivery of SDK capabilities, including authentication, account abstraction flows, signing, Miniapp interfaces, and key integrations.
• Quality & reliability: Partner with engineering to set standards for SDK performance, telemetry, backward compatibility, and semantic versioning.
• Feedback loops: Build tight feedback cycles with developers through beta programs, office hours, GitHub issues, surveys, and community channels.
• Documentation & enablement: Ship clear API references, guides, and sample apps; ensure release notes and changelogs are crisp and actionable.
• Cross-functional collaboration: Work closely with Engineering, Design, Developer Relations, and Compliance to deliver secure, usable, and well-documented releases.
• Metrics & outcomes: Define and monitor KPIs such as integration time-to-first-success, SDK adoption, version distribution, error rates, and developer satisfaction.

Qualifications

Required experiences

• Excellent written and verbal English; able to write crisp specs and developer-facing docs, and influence across teams.
• Comfortable operating in fast-paced, high-growth environments.

Nice-to-have

• Experience with Web3 wallets, account abstraction, or cryptography-adjacent developer platforms.
• Familiarity with dApp ecosystems and Miniapp-style integrations.
• Exposure to compliance and regulatory considerations for fintech/crypto platforms.
