Requirements
  • Personally shipped a production agentic artificial intelligence system used by real users, including memory or persistent state, tool use or tool calling, multi-step reasoning or workflows, and production deployment and operation.
  • Built or substantially contributed to a production multi-agent system, with understanding of agent routing and orchestration, specialist agent composition, dependency-aware workflows, parallel and sequential execution, conflicting agent outputs, and response synthesis.
  • Hands-on experience calibrating probabilistic machine learning or artificial intelligence systems, including Platt scaling, isotonic regression, Expected Calibration Error, reliability and calibration curves, and confidence and uncertainty estimation.
  • At least 5 years of professional experience in applied machine learning, artificial intelligence, or software engineering.
  • Strong Python skills.
  • Strong software engineering fundamentals.
  • Experience building and operating production systems.
Responsibilities
  • Design and ship specialist artificial intelligence agents that use memory, tools, data, and multi-step reasoning.
  • Build multi-agent orchestration that routes work between specialist agents, manages dependencies, and synthesizes conflicting outputs.
  • Develop systems that evaluate confidence, uncertainty, and consequence before recommendations reach a practitioner.
  • Build human-in-the-loop escalation so the system knows when to answer, ask for more information, or defer to a human.
  • Create workflows that turn sport scientist expertise into validated, versioned, and testable agent capabilities.
  • Build evaluation, observability, and regression testing so agent performance can be measured and improved in production.
  • Work with domain experts to ensure artificial intelligence outputs are grounded, traceable, and actionable.
Desired Qualifications
  • Experience with LangGraph, AutoGen, CrewAI, or equivalent frameworks.
  • Experience with production retrieval-augmented generation and reranking.
  • Experience with foundation-model fine-tuning or domain adaptation.
  • Experience with LoRA, PEFT, or similar techniques.
  • Experience with large language model observability and drift detection.
  • Experience with evaluation harnesses and automated regression testing.
  • Experience with human-in-the-loop architectures.
  • Experience with confidence thresholds and escalation models.
  • Experience with causal or counterfactual reasoning.
  • Experience with Go or Golang.
  • Experience with Amazon Web Services, including ECS, EC2, Lambda, SNS, or SQS.
  • Experience with GraphQL, REST, or gRPC.
  • Experience with PostgreSQL or MongoDB.
  • Experience working with sport scientists, clinicians, or other domain experts.
  • Familiarity with workload, readiness, recovery, biomechanics, or athlete performance data.

Simplify's Take

What believers are saying

  • Rav Singh Sandhu said in February 2026 Catapult smashed Stanford benchmarks internally.
  • The team says 2026 launch is coming, signaling active product momentum and urgency.
  • Hiring Founding AI Research Engineer and Senior Engineer roles suggests expansion before launch.

What critics are saying

  • Catapult still lacks a public 2026 launch, revenue proof, or customer-count disclosure.
  • LinkedIn and job posts show only a small founding team hiring in London.
  • Competitors like Notion, Slack, and Circle already own community workflows and user memory.

What makes Catapult unique

  • Catapult combines onboarding, profiles, and community operations in one workflow, reducing tool sprawl.
  • Rav Singh Sandhu said in 2025 Catapult pivoted after nine months of ideation.
  • The 2022 seed round from Blockchain Capital funded product development and early DAO integrations.
