Senior Software Engineer
About The Position
Arketa is hiring a Senior Software Engineer to build customer-facing AI products that help fitness and wellness studios automate operational work and grow. This is a product engineering role, with internal tooling and developer experience serving to increase the team's effectiveness. The engineer will also modernize core architecture and develop agentic workflows, CI, and observability that help a small team ship quickly. The role is part of a small, senior, fully distributed engineering team that operates with high autonomy and little process. The engineer will work closely with Staff engineers and engineering leaders and support mid-level and junior engineers through code review and pairing. The position involves building and improving product features across TypeScript, Node, NestJS, React, and Postgres, and taking features from ambiguous customer problems through shipping and measurement. Success includes shipping to production early, building context on the stack and ongoing migrations, owning a meaningful product or platform area, delivering AI functionality used by studios, and creating tools or safety nets that become part of the team's everyday shipping process.
Requirements
- In most cases, 5 or more years of software engineering experience; evidence of ability is valued more than years alone.
- Full-stack contributor willing to work across the stack; deep expertise in one area is welcome, but the role is not suited to someone who only wants to work in one layer.
- JavaScript and TypeScript background; candidates from adjacent ecosystems should be fluent and comfortable working in JS/TS.
- Regular, extensive use of AI tools beyond autocomplete.
- Meaningful contributions to a migration or large-scale refactor.
- Hands-on production reliability experience, including observability, alerting, and debugging live issues.
- A habit of improving the team through code review, pairing, and sharing knowledge.
- Strong product judgment and ability to scope ambiguous problems pragmatically and ship in small increments.
- Comfort working with high autonomy and little process.
Nice To Haves
- Experience building agentic workflows, evaluations, or automation.
- Personal interest in wellness and fitness.
- Experience building for entrepreneurs or small business owners, or having been one.
- Experience working at a high-growth startup.
Responsibilities
- Build AI products that help studio operators automate business operations.
- Build and improve agentic loops that strengthen the product, codebase, and delivery capability.
- Own features end to end, from scoping ambiguous customer problems to shipping and measuring outcomes.
- Simplify infrastructure and operations so human and agent engineers can work faster.
- Improve production safety nets by detecting, alerting on, and responding to issues.
- Work across TypeScript, Node, NestJS, React, and Postgres to ship features and improvements.
- Support teammates through thoughtful code review, pairing, mentorship, and sharing knowledge.
- Help the team adopt patterns and tools that make everyone more effective.
- Ship production work early, build context on the stack and migrations, and deliver workflow improvements.
- Own a meaningful area of the product or platform and deliver customer-facing AI functionality used by studios.
Benefits
- Competitive salary and stock options/equity.
- Unlimited paid time off.
- Medical, dental, and vision health insurance.
