$312k
Temporary

Aescape

Aescape is a New York-based physical AI and robotics company redefining human recovery through intelligent, precision bodywork, elevating it into a consistent, outcomes-driven practice.

Powered by real-time body mapping, advanced robotics, and proprietary software, Aescape delivers deeply personalized bodywork that continuously adapts to the individual. This creates a superior way for members to move with greater ease, recover more efficiently, and optimize how they feel every single day.

Aescape is building a defining brand for recovery, shifting behavior from a sporadic experience into a progressive, measurable routine, unlocking compounding benefits that build lasting resilience and laying the groundwork for an entirely new category of proactive human health and performance.

Aescape powers recovery across leading fitness, hospitality, and wellness environments, including Equinox, Life Time, Marriott, Hilton, Four Seasons, Pause Studios, and Remedy Place, and is backed by Valor Equity Partners, BroadLight Capital, and Mecha Ventures.

Aescape is looking for a Senior Backend Engineer (Booking Integrations, Contract) who can stand up and ship the services that connect Aescape to third-party booking platforms. You will set up the infrastructure for our third-party integration services, build three third-party booking platform integrations, and leave behind a setup that is easy to maintain. This is a contract engagement of 4 to 6 months with the possibility of extension or conversion to full time.

This role requires availability in core business hours Eastern Time (11am to 5pm ET) for candidates based anywhere in the US.

What You'll Do

  • Review Aescape’s service and infrastructure templates and set up a skeleton service that follows our template Go service and best practices

  • Set up the infrastructure for running the third-party integration services so ongoing maintenance stays light

  • Implement each booking platform integration within this infrastructure, communicating with Aescape’s general third-party booking integration service (3 total third-party platforms in this contract)

  • Work actively with the Aescape backend and infrastructure teams, giving feedback that improves the Aescape API and infrastructure template

  • Set up an infrastructure maintenance plan and hand off the work at the end of the engagement

  • Potential for future work: fixing integrations when third parties introduce breaking API changes, adding more booking providers, priority consideration when expanding the full-time roles on the backend team

What You’ll Bring

  • 5+ years of backend engineering, with recent production Golang experience

  • Experience building and shipping third-party API integrations in production, ideally booking, scheduling, payments or CRM systems

  • Experience taking a service from skeleton to production and handing it off with clear documentation

  • Comfort working with vendor APIs that are inconsistent or thinly documented

  • Experience with AWS and infrastructure setup for backend services

  • A track record of working independently, as a contractor or in a role with high ownership

  • Based in the United States and able to work as a 1099 independent contractor

Compensation : $150 per hour as a 1099 independent contractor, for an engagement of 4 to 6 months.
