• You’ll be expected to engineer kubernetes clusters, network-level request manipulation & proxying, scalable browser runtime clusters, and even implement cryptographic protocols (on the horizon).

• You’ll directly shape the technical architecture of our developer toolkit. By collaborating closely with the CTO, you will define and implement key features, API interfaces, database schemas, and select tools and technologies that drive our engineering team. This role involves a high degree of technical skill, innovation, and ownership in backend development.

Role responsibilities

• Design and maintain our APIs to ensure they are scalable, secure, and reliable. This includes designing interfaces, type systems, error models, database schemas, and authorization models.

• Contribute to our core SDK products by implementing new features and APIs, improving existing ones, and continuously refining the developer experience.

• Implement networking features like network traffic inspection and analysis, protocol-level request manipulation, and SOCKS5 + HTTP proxying.

• Develop and improve infrastructure capabilities including infrastructure-as-code and CI/CD using Pulumi, Flux, Tekton, Nix, and Cue.

• Ensure reliability and performance of our APIs by implementing test suites and telemetry to meet a high bar of quality.

• Manage releases of our SDKs and APIs through correct semantic versioning, crafting release notes, maintaining documentation, and updating sample projects.

• Write developer docs to facilitate seamless customer onboarding and write sample applications to demonstrate Anon’s functionality across its SDKs.

• Collaborate with internal teams including our design and frontend teams to align API, SDK, and infra development with company goals and client needs.

• Provide developer support to the customers integrating and utilizing our SDK, including addressing bugs, feature requests, and usability improvements.

• Stay up-to-date on the open-source universe including new frameworks, libraries, and tools that can be leveraged to improve our developer experience and product.

Experience required

• At least 2-4 years experience in developing SDKs, including all aspects from documentation to release management.

• Proficiency in backend service development (e.g. Typescript, Python, Rust, Go).

• Experience with API design across architectures such as REST, GraphQL, gRPC.

• Experience with maintaining versioned APIs and supporting backwards compatibility of SDKs.

• Experience with infrastructure management, Kubernetes, microservice architecture, and CI/CD.

• Familiarity with browser automation tools (e.g., Playwright, Puppeteer) and testing frameworks (e.g., Cypress, Vite).

• Familiarity with authentication and authorization protocols such as OAuth2 and OpenID Connect.

• Bonus points for experience with cryptography and cryptographic protocols.

• Bonus points for experience with low-level development of networking applications, including HTTP, TCP, and TLS.

• Bonus points if you have experience in building real-time streaming systems, preferably with WebRTC.

Skills required

• Strong skills in at least one backend language (Typescript, Python, Rust, or Go).

• Strong skills in self-learning and comprehending open-source code.

• Ability to function in a fast-paced environment where things change and you need to navigate ambiguity.
