About Future

At Future, we believe that personal connection is the key to progress. Our mission is to make world-class coaching accessible to everyone, helping people unlock their full potential through expert guidance, motivation, and accountability. As a digital personal training platform, we deliver highly personalized coaching, tailoring workout plans and support to each individual’s goals - all through a seamless app experience.

Since launching in 2017, Future has grown from a brainstorm in a San Francisco cafe into the nation’s largest provider of personal training sessions. In January 2025, Future announced its merger with Autograph, the company founded by 7x World Champion and entrepreneur Tom Brady. We’re poised for massive growth as we expand our brand, forge new partnerships with some of the world’s most iconic athletes, and harness AI to enhance and scale our coaching experience.

As we continue to grow, we’re investing in cutting-edge technology, deepening our roster of elite coaches, and building new partnerships. If you're passionate about shaping the future of fitness, come join us - we’re just getting started.

About the Role

We're looking for an Applied AI Engineer to help us build and ship AI-powered features that directly improve our product experience and business outcomes. This is a hands-on, product-focused role where you'll take ideas from concept to production — designing intelligent systems, validating them with real users, and turning them into reliable, scalable services.

You'll work at the intersection of AI, product, and engineering — partnering closely with cross-functional teams to identify high-impact opportunities, prototype quickly, and iterate based on data. This isn't a research-only role. You'll own the full lifecycle: experimentation, evaluation, deployment, monitoring, and continuous improvement.

The ideal candidate is excited about applying LLMs and modern ML tooling to real-world problems. You think in terms of systems, tradeoffs, and outcomes — not just models. You care about performance, quality, latency, and cost in production. Most importantly, you're motivated by shipping impactful AI experiences that customers actually use.

What You'll Do

  • Build and ship AI agents that serve real users: tool-calling LLM systems with structured output, parallel API orchestration, and streaming responses.
  • Design evaluation harnesses and quality scoring — we use Langfuse, rubrics to measure safety, effectiveness, and personalization.
  • Own the full loop: prototype a new agent capability, validate it with evals, deploy it to staging and production, monitor traces, and iterate.
  • Improve reliability, latency, and cost through prompt caching strategies, token budgets, retry logic, and observability.
  • Write the tools agents use: API integrations with Pydantic validation, exercise search over local databases, structured workout submission.

What You Bring

  • Strong Python skills: you've built and deployed services on large production systems.
  • Experience with LangChain/LangGraph or similar agent frameworks.
  • Hands-on experience with LLMs in production: prompt engineering, tool/function calling, structured output, evaluation.
  • Comfort with async Python, HTTP APIs, and streaming protocols (SSE, webhooks).
  • Experience with data validation and schema design (Pydantic, JSON Schema).
  • Ability to debug across layers: from a broken LLM tool call to a misconfigured Terraform resource.
  • Clear communication: you'll work directly with product, mobile, and backend engineers.

Nice to Have

  • Familiarity with AWS (Bedrock, ECR, CloudFront, S3, Cognito) or other cloud agent hosting.
  • Observability and tracing tools (Langfuse, OpenTelemetry, Datadog).
  • Exposure to evaluation frameworks: LLM-as-a-judge, automated scoring, dataset management.
  • Infrastructure-as-code (Terraform, CDK).

Compensation & Benefits

We believe great people should be well paid and meaningfully invested in what they're building.

Base Salary $ 215,000– $ 250,000/ year + equity. The salary range is set based on multiple considerations including business needs, market demands, talent availability, experience, and unique skills and attributes. The base pay range is subject to change and may be modified in the future.

Equity Equity participation offered alongside base compensation.

Health Coverage Comprehensive medical, vision, dental, and disability insurance plus tax savings accounts for all eligible employees.

Retirement 401(k) plan with tax-advantaged savings options.

Remote-First Employment eligible to all employees located anywhere in the continental US. No travel required.

Wellness & Development Monthly health and fitness stipend contributing to overall wellbeing, access to a mental health platform, reimbursement for medical travel, and an annual learning & development stipend.

Flexible Time Off Flexible PTO so you can rest, recharge, and take care of life outside of work.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
