The team To sustain the company's growth, Ledger is looking for an Engineering Manager to lead the Cloud Wallet team. This team is responsible for the backend services that power blockchain account management, transaction processing, and on-chain data aggregation across all Ledger wallet surfaces, from Ledger Live to the Ledger Enterprise platform. We believe in the power of functional programming to build robust and scalable platforms. We take time to share, challenge, and grow together through bi-weekly knowledge-sharing sessions, meetups, conferences, and open source contributions. What you’ll be doing - Lead and grow your team. Own hiring, onboarding, performance management, and the professional development of your engineers. Run regular 1:1s, support career growth, and build a high-performing, engaged team. - Drive technical delivery. Own the team's roadmap and PI planning commitments. Ensure on-time, high-quality delivery across the team's service portfolio and ongoing architectural initiatives while coordinating across dependencies with Coin Integration, Ledger Enterprise, Ledger Live, and Infrastructure teams. - Maintain operational excellence. Own SLIs/SLOs for team services. Lead incident response posture, on-call culture, and observability standards for production-critical systems. - Architect for scale and reliability. Partner with tech leads and staff engineers to drive sound technical decisions on a polyglot stack (TypeScript, Scala) handling high throughput, multi-chain complexity, and strict reliability requirements. Review ADRs and ensure architectural coherence. - Champion engineering practices. Drive strong standards on CI/CD, testing (including end-to-end on testnets), code review quality, technical debt management, and AI-assisted engineering workflows. - Contribute to org-level initiatives. Participate in cross-BU architectural working groups, PI planning, and engineering efficiency programs. You will collaborate cross-functionally with: - The Blockchain platform team for data model alignment, indexing and event streaming - The Coin Integration team for coin module ownership and new blockchain integrations - The Ledger Enterprise team for enterprise wallet features and operational alignment - The Ledger Live / Wallet XP teams as consumers of the team's backend APIs - The Infrastructure and SRE teams for platform reliability and scalability - The Product team for roadmap prioritization and customer-driven requirements - The Security team for vulnerability analysis and compliance What we’re looking for - Proven experience (3+ years) managing backend engineering teams in a product-driven, distributed environment - Strong technical background in backend systems. You can credibly challenge architectural decisions, review design documents, and unblock engineers on hard technical problems - Experience operating services at scale and familiarity with high-availability architectures, event-driven systems, and observability tooling (RabbitMQ, PostgreSQL, Flink, NATS, Datadog or equivalent) - Comfortable with polyglot stacks. The team works across TypeScript and Scala; you don't need to be an expert in both but need enough depth to lead effectively - Track record of navigating complex multi-team dependencies and influencing across organizational boundaries without direct authority - Excellent written and verbal communication skills in English - Bonus points: exposure to blockchain or crypto infrastructure (account indexing, transaction lifecycle, UTXO vs account-based models), and a genuine interest in the Web3 space
