Full Job Description
About the Role:

webAI is seeking a Senior Platform Engineer to build the core software platform that supports our enterprise and consumer products.

You will design and implement reusable platform capabilities and expose them through stable APIs and SDKs. Your work will span systems architecture, backend development, automated delivery, documentation, and developer experience.

This role is suited to an engineer who can move between low-level technical concerns and clear, practical interfaces for other developers. You will own complex work from design through release while helping shape the boundaries and evolution of the webAI platform.

Key Responsibilities:
  • Design and build reliable platform capabilities shared across webAI products.
  • Develop backend and systems software with a focus on performance, security, maintainability, and operational reliability.
  • Create clear, stable APIs and SDKs for internal and external developers.
  • Own features from architecture and implementation through testing, packaging, release, and production support.
  • Build and improve CI/CD pipelines for multi-platform builds, automated testing, artifact publishing, and releases.
  • Establish sound practices for API evolution, versioning, compatibility, and migration.
  • Write documentation, examples, and reference implementations alongside the APIs they explain.
  • Diagnose performance, concurrency, reliability, and integration problems across complex systems.
  • Collaborate with product and engineering teams to turn product needs into reusable platform capabilities.
  • Improve developer tooling and workflows as the platform and SDK ecosystem grow.


Required Skills & Qualifications:
  • 5+ years of relevant software engineering experience.
  • Strong experience designing and maintaining APIs, SDKs, client libraries, or developer-facing platform interfaces.
  • Strong systems-engineering skills, including experience with concurrency, process boundaries, resource management, failure modes, and performance.
  • Experience designing and maintaining CI/CD pipelines and release automation.
  • Experience packaging, versioning, and distributing production software.
  • Ability to write maintainable code, effective tests, clear technical documentation, and useful examples.
  • Experience diagnosing complex integration, reliability, and performance problems.
  • Proven ability to take complex or ambiguous requirements through design, implementation, and release.
  • Strong communication and cross-functional collaboration skills.
  • Bachelor's degree in Computer Science, Software Engineering, or a related technical field.


Preferred Skills & Qualifications
  • Professional experience with Rust.
  • Experience building distributed, peer-to-peer, offline-capable, or edge systems.
  • Experience designing or integrating foreign function interfaces (FFI) and language bindings.
  • Experience working across programming-language and process boundaries.
  • Familiarity with semantic versioning, compatibility policies, and API migration strategies.
  • Experience building cross-platform software for desktop, mobile, server, or embedded environments.
  • Experience creating developer tools, code generators, build tooling, or release infrastructure.
  • Experience with security-sensitive or privacy-preserving systems.


We at webAI are committed to living out the core values we have put in place as the foundation on which we operate as a team. We seek individuals who exemplify the following:
  • Truth - Emphasizing transparency and honesty in every interaction and decision.
  • Ownership - Taking full responsibility for one's actions and decisions, demonstrating commitment to the success of our clients.
  • Tenacity - Persisting in the face of challenges and setbacks, continually striving for excellence and improvement.
  • Humility - Maintaining a respectful and learning-oriented mindset, acknowledging the strengths and contributions of others.

  • Comprehensive health, dental, and vision benefits package.
  • 401k Match
  • $200/mos Health and Wellness Stipend
  • $400/year Continuing Education Credit
