Description

Software is eating the world, but AI is eating software. We live in unprecedented times – AI has the potential to exponentially augment human intelligence. Every person will have a personal tutor, coach, assistant, personal shopper, travel guide, and therapist throughout life. As the world adjusts to this new reality, leading platform companies are scrambling to build LLMs at billion scale, while large enterprises figure out how to add it to their products.

At Scale, our products include the Generative AI Data Engine, SGP, Donovan, and others that power the most advanced LLMs and generative models in the world through world-class RLHF, human data generation, model evaluation, safety, and alignment. The data we are producing is some of the most important work for how humanity will interact with AI.

In this role, you will support the design and development of shared platforms used across Scale. This includes designing our foundational data platforms and lifecycle, architecting Scale’s core cloud infrastructure and orchestration stack, and redefining how engineers develop, build, test, and deploy software at Scale. You’ll also get widespread exposure to the forefront of the AI race as Scale sees it in enterprises, startups, governments, and large tech companies.

Responsibilities:

  • Drive the design, and implementation of our foundational platforms and systems, working closely with stakeholders and internal customers to understand and refine requirements.
  • Collaborate with cross-functional teams to define, design, and deliver new features.
  • Proactively identify opportunities for, and drive improvements to, current programming practices, including process enhancements and tool upgrades.
  • Present technical information to teams and stakeholders, providing guidance and insight on development processes and technologies.

Requirements:

  • 3+ years of full-time engineering experience, post-graduation with specialities in back-end systems.
  • Extensive experience in software development and a deep understanding of distributed systems and public cloud platforms (AWS preferred).
  • Show a track record of independent ownership of successful engineering projects.
  • Possess excellent communication and collaboration skills, and the ability to translate complex technical concepts to non-technical stakeholders.
  • Experience working fluently with standard containerization & deployment technologies like Kubernetes, Terraform, Docker, etc.
  • Experience with orchestration platforms, such as Temporal and AWS Step Functions.
  • Experience with NoSQL document databases (MongoDB) and structured databases (Postgres).
  • Strong knowledge of software engineering best practices and CI/CD tooling (CircleCI).

Nice to haves:

  • Experience with data warehouses (Snowflake, Firebolt) and data pipeline/ETL tools (Dagster, dbt).
  • Experience with authentication/authorization systems (Zanzibar, Authz, etc.)
  • Experience scaling products at hyper-growth startups.
