At Brain Co., we focus on applying frontier AI to real institutional challenges, working alongside governments, healthcare systems, and critical industries to modernize how essential services operate.

We are looking for leaders who want to help bring new technology into institutions that impact millions of people.

About the role:

You'll join the team that builds and enables agentic workflows across Brain Co. For every engineer, operator, and business team internally, and for the production AI systems we deploy to governments, healthcare systems, and critical industries. This is a platform role at the center of the company's agent-first strategy: you'll build foundational systems used by every engineering team, and the bar is product-grade because the entire company depends on them.

What you’ll work on:

  • Own the foundations of how LLMs are used across the company: cost visibility and controls, data privacy, identity and access, routing, and the security posture around all provider traffic.

  • Design the sandboxing, orchestration, audit, and guardrail layers that product teams build their agents on, so verticals don't need to invent their own abstraction.

  • Solve the hard problems: prompt-injection defenses, scoped credentials, kill switches, multi-tenant isolation (including VM-level pod isolation), and runaway-cost controls.

  • Design the orchestration, isolation, and resource models that make this viable: cold-start vs. always-on tradeoffs, credential and token lifecycle, fan-out and fan-in patterns, fairness and quota enforcement across tenants, and the observability needed to debug at that volume.

  • Make AI-assisted development a first-class platform layer: coding agents that review and ship code, automate CI, refactor at scale, and run as background workers across the codebase, together with the canonical scaffolding and guardrails that govern them.

  • Build the systems that let every team; engineering, operations, and the business, run their own agents reliably and safely against the tools they already use, with the right credentials, scheduling, memory, and audit underneath.

  • End-to-end ownership: architecture, implementation, rollout, observability, on-call, and iteration based on internal user feedback.

  • Partner closely with security, infrastructure, and product teams to make agent deployments safe by default.

You Might Be a Great Fit If You…

  • Have 5+ years building backend systems in production, with deep proficiency in at least one of Python, TypeScript, Go, or Rust.

  • Bring strong fundamentals in distributed systems: consistency, idempotency, retries, failure modes, queueing, scheduling.

  • Have designed and operated APIs and services that other engineers depend on.

  • Have a proven track record building shared infrastructure, internal platforms, or developer-facing services that real users adopted.

  • Have strong intuition for developer experience, long-term maintainability, and where to draw abstraction boundaries.

  • Are comfortable owning the full lifecycle: writing the design doc, shipping the MVP, hardening it, and driving adoption across the company.

  • Have owned services with real uptime and operational responsibility, and are comfortable with observability stacks, incident response, and SLOs.

  • Bring cloud-native experience: Kubernetes, infrastructure-as-code, OAuth/OIDC, secrets management.

Ways you might stand out:

  • Experience building or operating LLM infrastructure: gateways, inference systems, prompt routing, cost attribution, evaluation harnesses.

  • Experience with agent frameworks, tool-use systems, or sandboxed code execution.

  • Security instincts around prompt injection, supply-chain risk in agent ecosystems, and credential scoping for autonomous systems.

  • Background in multi-tenant, regulated, or government deployments (HIPAA, SOC2).

  • Open-source contributions to AI infrastructure, agent tooling, or developer platforms.

Why Join Us

  • Collaborate with industry veterans from Tesla, DeepMind, Databricks, and more

  • Accelerate your career with ownership based on impact, not tenure

  • Earn competitive compensation + meaningful equity in a high-growth company

  • Thrive in a culture built on speed, curiosity, and impact

Benefits

  • Competitive salary plus equity

  • Daily lunches

  • Commuter benefits

  • 401(k)

  • Medical, Dental and Vision

  • Unlimited PTO

Company Information

Company Name: Brain Co.

Company Website: https://www.braincorp.com

Company Address: California (USA)

Brain Corp (commonly branded as Brain Corp) is a technology company that develops artificial intelligence (AI) software and systems to enable autonomy for commercial mobile robots. The company focuses on producing a software platform that equips wheeled machines—particularly those used for facility services, light industrial handling, and retail environments—with perception, navigation, and fleet-management capabilities so they can operate safely and efficiently in human-populated indoor spaces. Brain Corp’s offerings are centered on software-first solutions that are integrated by original equipment manufacturers (OEMs) and service providers into a variety of hardware platforms rather than being a pure hardware manufacturer itself. At the core of Brain Corp’s business is BrainOS, a proprietary operating system and AI stack designed to control autonomous mobile robots (AMRs). BrainOS combines computer vision, sensor fusion, mapping and localization (SLAM), path planning, obstacle avoidance, and task orchestration to allow robots to navigate complex indoor environments such as shopping centers, airports, hospitals, warehouses, and commercial buildings. The platform is built to run on constrained embedded hardware typical of commercial machines and is supplied to partners as a software package and integration toolkit. In addition to onboard autonomy, Brain Corp provides back-end infrastructure for fleet management, remote diagnostics, software updates, performance analytics, and operator tools for configuring and supervising multiple units across one or more sites. Brain Corp’s go-to-market approach emphasizes collaboration with equipment manufacturers, facility service providers, and systems integrators. Rather than competing head-on with every robot OEM, the company licenses BrainOS to established manufacturers of cleaning machines, industrial vehicles and other service equipment who integrate the software into their product lines to create autonomous or semi-autonomous variants. This partner-centric strategy allows Brain Corp’s technology to scale through the distribution channels and customer bases of recognized hardware brands. The company also works directly with large enterprise customers and facilities-management organizations to pilot and deploy fleets of robots performing repetitive, safety-sensitive, or time-consuming tasks. Common application areas for Brain Corp–powered systems include autonomous floor cleaning and maintenance (carpet and hard-floor cleaning machines), last-meter material handling, goods movement in distribution and retail backrooms, and other indoor logistics tasks where predictable mobility and safe interaction with bystanders are essential. Onboard perception stacks are tailored to detect people, obstacles and dynamic changes in the environment; the software supports behavior policies and safety layers required for operating in public, staff, and mixed-traffic areas. In practice, deployments have emphasized reliability, ease of integration with existing operations, and tools for measuring productivity improvements such as area cleaned, cleaning time per shift, route adherence and uptime. The company’s commercial offering typically includes a combination of licensed BrainOS software, on-robot compute or support for partner hardware, cloud-based fleet management services, professional services for integration and commissioning, and ongoing software support/updates. Brain Corp has positioned these elements to appeal to both OEMs seeking to add autonomy to their product lines and enterprise customers seeking to automate repetitive tasks without building robotics capabilities in-house. The business model includes recurring revenue components tied to software licensing and fleet-management subscriptions in addition to professional services and integration fees. From a technology standpoint, Brain Corp invests in perception algorithms (including deep learning–based object detection and semantic understanding), robust localization and mapping for dynamic indoor settings, safe motion planning, and scalable fleet orchestration. The software stack is engineered to handle varied lighting conditions, cluttered environments and human traffic, and includes redundancy and safety monitoring to meet regulatory and customer safety expectations. The company also provides developer and integrator tooling to adapt BrainOS to different form factors and payload configurations, enabling partners to reuse the autonomy stack across multiple product families. Brain Corp’s customers and partners have included equipment manufacturers and service providers in the commercial cleaning, facilities management and light industrial markets. The company’s technology has been used to enable autonomous variants of floor-care machines and other service robots that operate in retail, hospitality, healthcare, transportation hubs and large enterprises. In practice, these deployments are intended to augment human workers by taking on routine, repetitive tasks so staff can be redirected to higher-value activities such as customer service, technical maintenance and oversight. Operational support and measurement are important elements of Brain Corp’s value proposition. The company supplies cloud dashboards, remote monitoring, and analytics that provide operators with visibility into fleet health, utilization, and task outcomes. This data-centric approach is used to demonstrate ROI, optimize routing and scheduling, and prioritize maintenance. Brain Corp also invests in field support and integration services to ensure that autonomous machines meet customers’ operational requirements and safety standards during commissioning and long-term operation. In summary, Brain Corp is a technology company specializing in AI and autonomy for commercial mobile robots. Its primary product, BrainOS, is an integrated autonomy platform supplied to OEMs and enterprise customers to enable navigation, perception, fleet management and analytics for indoor service and light industrial robots. The company’s business model centers on software licensing, cloud services and integration partnerships that allow established equipment manufacturers and facilities operators to add or scale robotic automation in commercial settings.
