Principal Software Engineer

This is a high-impact role for a technical leader who thrives on deep systems work and cross-disciplinary problem solving. You will work closely with engineers, ML researchers, product managers, and executives to define the architecture and foundational components that will support the next generation of intelligent, interactive systems. Your decisions will influence the trajectory of multiple engineering teams and the product itself.

This position is remote.

You’ll make an impact by:
Define and evolve the technical architecture across core systems and products
Provide hands-on technical leadership on strategic projects
Lead technical reviews and mentor engineers across all levels
Align engineering direction with product and ML research priorities
Identify and address scaling challenges before they become bottlenecks
Champion engineering excellence, reliability, and system sustainability
Technologies We Use
Languages: Python, Go, TypeScript
ML: PyTorch, HuggingFace, ONNX Runtime, LangChain
Infrastructure: AWS, Kubernetes, Redis, Postgres, S3, Terraform
DevOps & Observability: GitHub Actions, Datadog, Grafana, Prometheus
We do not expect deep experience with every tool, but we are looking for engineers who have repeatedly solved difficult problems at scale, and who know how to make good technical decisions under uncertainty.

You will win us over by having the following qualifications:

Basic Qualifications
10+ years of professional software development experience
Experience designing and scaling distributed systems and real-time applications
Proven ability to lead technical strategy and cross-team architecture efforts
Proficiency in at least one backend systems language (e.g., Python, Go, Java)
Strong understanding of system design, performance optimization, and fault-tolerance
Preferred Qualifications
Experience bridging machine learning research and production environments
Background in building systems that operate in or interact with the physical world
Ability to influence engineering orgs and contribute to hiring and culture
Track record of mentoring senior and staff-level engineers
