Chronos AI – Technology Summary
Chronos AI has developed a next-generation 3D geolocation and situational-awareness platform that operates without GPS, cell towers, or internet. Our system creates a self-calibrating mesh using UWB/BLE/Wi-Fi/LoRa nodes (“anchors” and “tags”), deployable on drones, vehicles, and fixed infrastructure in seconds. We deliver sub-meter accuracy indoors, outdoors, and underground, with both active tracking (people/equipment) and soon, advanced passive RF detection (phones, radios, unknown emitters).

 

This capability is now being integrated into defense systems, public safety platforms, smart buildings, and mobile robotics, and is supported by multiple U.S. DoD engagements (U.S. Navy CRADA, DARPA, SOCOM/AFSOC submissions).

What Chronos AI Is Looking for through MIT CSAIL

About Korl

Korl uses AI to automatically generate personalized, customer-specific presentations for critical business moments like QBRs (Quarterly Business reviews) and renewals. We're solving a real pain point by helping companies showcase their value to customers through data-driven, tailored content instead of generic templates. Our platform connects to tools like Salesforce, Jira, and Figma to build a holistic view of products and customers, then uses AI to craft compelling narratives.

Who We're Looking For

We're looking to hire passionate Computer Science students for full-time positions. We're seeking builders who are excited about:

• Designing and building scalable distributed systems and APIs.

• Working with cutting-edge AI/ML technologies (LLMs, agentic workflows).

• Tackling complex data integration and transformation challenges.

• Creating products that have an immediate, visible impact on customers.

What You'll Work On

We all contribute directly to core infrastructure and AI projects. Some of the more important projects and technologies:

• Centralized Data Access Service (CDAS): Build our unified data layer using Google Cloud Run, gRPC, and Protocol Buffers. You'll tackle challenging problems in schema versioning and data transformation, and create elegant abstractions for complex data models that serve as the backbone of our entire platform.

• Integration Platform: Design the systems that rapidly connect to external services (Salesforce, HubSpot, etc.) and normalize their data. This is a crucial, high-impact project for generating customer-specific insights at scale.

• AI-Powered Presentation Generation: Work with Large Language Models (LLMs) and agentic AI systems to automatically create tailored content. You'll handle large-scale data processing and build intelligent workflows that know precisely when to leverage AI versus when to rely on deterministic logic.

Robotics R&D Intern – Large Behavior Models & Dual‑Arm Manipulation

(Spring/Summer 2026)

Location: Cambridge, MA — (In-person, MassRobotics). Duration: 12–16 weeks | Spring

(Jan–Apr, part-time available) and/or Summer (May–Aug, full-time) 2026

About IntuitiveMotion.AI

Born out of Harvard Business School and UT Austin’s renowned robotics community,

IntuitiveMotion.AI is building end‑to‑end manipulation systems that combine data‑efficient

classical robotics with emerging Large Behavior Model (LBM) methods. Our mission is to

unlock reliable, scalable automation for dynamic, human‑centric workspaces—beginning

in hospitality and adjacent verticals.

Why This Role Matters

In the next 12 months we will harden our software stack and expand from a single

customer pilot to several multi‑site deployments. Your research and engineering will

directly influence the robustness, adaptability, and scientific rigor of that scale‑up.

What You’ll Work On

• Hybrid Modeling Pipeline: Organize and expand our data pipelines, feeding

analytically generated trajectories into LBM pre‑training and richly annotated

tele‑op demonstrations into subsequent fine‑tuning—all within a unified, modular

framework.

• Demonstration Infrastructure: Strengthen and extend our existing tele‑operation

stack—improving latency, tactile feedback, and operator UX—while scaling data

ingestion and labeling pipelines.

• Simulation‑Based Testing & Validation: Build automated test harnesses in

simulation to stress‑test policies (robustness, regression, safety) and benchmark

performance under domain randomization before new hardware deployments

• System Reliability at Scale: Contribute to CI/CD, monitoring, and fault‑recovery

that will keep a fleet of robots productive and safe in production next year.Ideal Profile

• Currently pursuing a PhD or exceptional MS in Robotics, CS, EE

(Spring/Summer 2026 availability).

• Published or project experience in at least one: imitation learning, reinforcement

learning, manipulation, sim‑to‑real, or robotic perception.

• Proficient in Python/C++ and modern ML toolchains (PyTorch, JAX, or TensorFlow).

• Solid grasp of control theory, kinematics, and motion planning.

• Comfortable debugging on real hardware (ROS 2, MoveIt, NVIDIA Jetson/Orin, Dell

Aurora or similar).

Nice to Haves

• Experience with dual‑arm or mobile manipulation platforms.

• Statistical experiment design or MLOps background (e.g., A/B testing frameworks).

Founding Software Engineer | Brace Health

Location: Cambridge, MA (In-person) Job Type: Full-Time

We’re building a new financial infrastructure of healthcare—reimagining how patients access coverage and how providers get paid. Our goal: reduce the cost of healthcare with purpose-built AI agents that streamline the billing maze so clinics can invest in care, not paperwork.

We’ve raised ~$4M from Bessemer Venture Partners (backers of Shopify, LinkedIn, and Toast), grown 10x in the last 60 days, and built a 6+ month customer waitlist with no sales/marketing.

We're now assembling a world-class founding engineering team. You’ll work alongside a technical founding team with backgrounds at Microsoft, Amazon, Meta, and Bain, and help shape the systems that power the future of healthcare.

What will you do:

● Core Systems Development: Build vertically integrated infrastructure that automates medical billing from end to end. Own mission-critical backend systems using Rust, Python, Kubernetes.

● AI-Driven Automation: Design and deploy production AI/ML systems that navigate complex payer rules and workflows. Work across LLMs, traditional ML, and multi-agent architectures.

● End-to-End Product Ownership: Build beautiful, high-performance frontend experiences with React, Remix, TypeScript. Collaborate directly with users to ship fast and improve constantly.

● Infrastructure & Reliability: Design for resilience, scale, and performance. Own our deployment stack across AWS, Kubernetes, and modern observability tools.

● Team & Culture: Join a small, elite team with high ownership. Help shape engineering culture, mentor peers, and lay the technical foundation for a category-defining company.

Who you are:

● A builder. You’ve owned and shipped complex systems in production, and you like to move fast without breaking things.

● Mission-driven. You care about building tools that improve people’s lives—and you’re energized by the chance to fix healthcare’s most painful problems.

● Gritty and curious. You learn quickly, ask good questions, and keep pushing until things work.

Our Stack:

● Rust for backend services: safe, fast, and reliable

● React + Remix + TypeScript for delightful user interfaces

● Python for AI/ML workflows

● AWS + Kubernetes for scalable infrastructure

● LLMs from OpenAI, Anthropic, Gemini, and open source

Why this matters:

Healthcare is the largest and most essential market in the world—but it’s riddled with complexity and inefficiency. Americans carry over $200B in medical debt, while providers spend $300B+ per year just trying to get reimbursed by insurance. The system is opaque, expensive, and broken—for both patients and doctors.

We believe this can be better. By rebuilding the billing layer with modern software and AI, we can unlock massive value: better access for patients, better economics for clinics, and less waste across the entire system.

Join Us: This is a rare opportunity to help architect foundational infrastructure in a trillion-dollar industry. If you're hungry to solve real problems, move fast, and build something that matters—we want to meet you
