Job Description

We have an opening to hire a Senior Software Engineer - SDK (Client Runtime). Our team makes the Temporal SDKs — our SDKs are the primary mechanism through which our customers use Temporal. This is harder than it sounds. SDKs are not thin clients; they act as runtime environments for application code, contain complex internal logic, and coordinate closely with Temporal Server to provide the durable-execution guarantees our customers require. Most of our work is open source.

Job Responsibility

  • Take end-to-end ownership of new features
  • Design and build Temporal SDKs used by customers
  • Tightly integrate Temporal SDKs with their respective languages
  • Develop features that provide a foundation for the reliable execution of the current wave of agentic AI systems
  • Work directly with our community to debug issues
  • Write publicly-readable technical documentation
  • Go the extra mile to support a customer in need
  • Travel to meet your coworkers for a week once or twice a year
  • Attend the occasional developer conference

Requirements

  • Minimum 10 years experience post graduation writing scalable software
  • BS or MS in Computer Science (or a closely-related degree), or equivalent work experience writing production-grade software
  • Fluency in multiple programming languages, and an affinity for learning new ones
  • Deep experience with concurrent programming
  • Deep experience with distributed systems
  • Experience designing APIs and writing documentation for publicly-available libraries or modules
  • A methodical, detail-oriented approach to your work
  • Strong technical communication skills—written and verbal—in English
  • A deep sense of ownership and personal accountability
  • A proactive approach to managing your work

Nice to have

  • Familiarity with Temporal’s programming model
  • Experience writing in Go, Java, Python, .NET, TypeScript, Ruby and/or Rust
  • Experience contributing to open source projects
  • Experience contributing to the architecture and design of large-scale distributed systems
  • Deep knowledge of language runtimes

What we offer

  • Unlimited PTO, 12 Holidays + 2 Floating Holidays
  • 100% Premiums Coverage for Medical, Dental, and Vision
  • AD&D, LT & ST Disability, and Life Insurance
  • Empower 401K Plan
  • Additional Perks for Learning & Development, Lifestyle Spending, In-Home Office Setup, Professional Memberships, WFH Meals, Internet Stipend
  • $3,600 / Year Work from Home Meals
  • $1,500 / Year Career Development & Learning
  • $1,200 / Year Lifestyle Spending Account
  • $1,000 / Year In-Home Office Setup
