• Collaborate effectively with other teams when needed, proactively unblocking technical topics and clearly communicating progress, risks, decisions, and results to the relevant stakeholders.
• Contribute to the Pennylane tech community through technical content, onboarding, interviews, incident resolution, tech initiatives, meetups, or other community-building activities.
