Trusted by top brands like Strava, Nextdoor, Patreon, and Adobe, we’re on a mission to make real-time communication and social experiences seamless for developers and their users.

Role Overview

We’re seeking a Staff Python Engineer to lead the development of our open-source video/voice AI Python library. In this high-impact role, you’ll architect, build, and maintain a powerful toolkit for developers integrating voice and video AI into their products. You’ll be a key technical leader—shaping the direction of the library, collaborating with cross-functional teams, and engaging with the open-source community.

Location: Office in Amsterdam or Remote (preferred EU/US time zones). Occasional travel for in-person collaboration and meetups is encouraged.

Hybrid policy: applicants based in the Netherlands or relocating here are expected to work in the office in Amsterdam 3 times per week. Exemptions apply to specific cases.

What will you work on

• Architect, develop, and maintain our open-source video/voice AI Python SDK and library, from API design to performance tuning.
• Ensure the library is well-documented, thoroughly tested, and easy for developers to adopt and extend.
• Drive code quality through robust testing, benchmarking, and automation.
• Contribute to and engage with the open-source community: triage issues, review contributions, and shape the roadmap through feedback.
• Collaborate cross-functionally with product, UX/design, and other engineering teams to align on developer workflows and UX.
• Mentor engineers, establish best practices, and advocate for strong Pythonic design and high engineering standards.

About You

• 5+ years of production-level Python software engineering experience, ideally in SDK development.
• Proven experience building or maintaining open-source libraries or SDKs, with strong community engagement.
• Deep understanding of Python ecosystem tools.
• Track record of leading technical projects and mentoring engineers.
• Excellent communication skills and comfort collaborating across teams (product, design, ML, open-source contributors).

Preferred

• Experience with real-time processing systems, low-latency streaming, or WebRTC.
• Contributions to voice/video open-source projects or AI model repositories.
• Experience with Go (all of Stream’s APIs use Go, so it helps when interacting with other teams).

Why You’ll Love This Role

• High Impact: Shape a key piece of open-source infrastructure powering voice/video AI for developers worldwide.
• Open Source & Community-Driven: Influence the development of a library used and shaped by global contributors.
• Startup Vibe: Join an ambitious, high-energy team that values excellence, collaboration, and fast-paced iteration.
• Flexibility & Trust: Choose your work style—join us in Amsterdam, Boulder, or work remotely—with periodic in-person collaboration.

What We Have To Offer You

• A team of exceptional (and friendly) engineers.
• The chance to work on OSS projects.
• 28 days paid time off plus paid Dutch holidays.
• Company equity.
• A pension scheme.
• A Learning and Development budget.
• Commute expenses to Amsterdam covered or the option to use a company bike within the city.
• Fitness stipend.
• Monthly in-office chair massages by a professional.
• MacBook Pro.
• Healthy team lunches and plenty of snacks.
• A generous relocation package.
• An office in the heart of Amsterdam.
