Founded in Silicon Valley in 2009 by Marc Andreessen and Ben Horowitz, Andreessen Horowitz (aka a16z) is a venture capital firm that backs bold entrepreneurs building the future through technology. We are stage agnostic. We invest in seed to venture to growth-stage technology companies, across AI, bio + healthcare, consumer, crypto, enterprise, fintech, games, and companies building toward American dynamism. a16z has $100B+ under management across multiple funds.

We’ve established a team that is defined by respect for the entrepreneur and the company-building process; we know what it’s like to be in the founder’s shoes. We’ve invested in companies like Anduril, Airbnb, Coinbase, Cursor, Databricks, Deel, Figma, GitHub, Roblox, SpaceX, and Stripe. Our team is at the forefront of new technology, helping founders and their companies impact and change the world.

The Role

You will join the Applied Software Group (ASG), a team of experienced individual contributors building internal software tools for the firm's investing and operations teams. As a software engineer optimizing developer experience, you will own, improve and help with the adoption of our internal developer platform as well as the team's wider product portfolio. You will work on and own the infrastructure and tooling that the team and its partners are building with.

The Applied Software Group operates in the mode of an internal startup. We own a tight feedback loop with our users and take on requests from all corners of the firm. In this role, your users are your fellow colleagues — you'll understand their pain points, eliminate friction from their daily workflows, and build the platform and tools that lets everyone build more, faster, and with confidence.

• Continuously work with your fellow colleagues to understand, review and assist their diverse use-cases for projects
• Build and maintain shared tooling, templates, and internal libraries that accelerate development across the firm’s products
• Support observability, monitoring, and alerting so engineers can self-serve when things break in production
• Collaborate with the Cybersecurity team to help ensure developer workflows meet security and compliance requirements
• Write and maintain developer documentation, onboarding guides, and runbooks that actually get used
• Ship improvements iteratively, incorporating feedback from your users to continuously improve the developer experience
• Take ownership of assigned projects and services, from development through production support, with increasing autonomy over time
• Write clear, well-structured, and maintainable code
• Bring positive energy in every interaction with the team and foster inclusive collaboration
• Stay curious about new tools, technologies, and approaches relevant to infrastructure and developer productivity
• Learn the inner workings of VC and work closely with the investing partnership
