Staff infrastructure engineer on Multiply Labs' Software Infrastructure team, building and running the AWS cloud services, OTA update/configuration systems, and CI/CD pipelines that keep a fleet of biologics-manufacturing robots highly available and secure. Core stack: AWS (Lambda, IoT Core, DynamoDB), Docker/Kubernetes, Python, Terraform/CloudFormation, and Linux.
Forward Deployed Software Engineer
A forward deployed engineer who splits time between writing production Python/TypeScript code for an LLM-powered platform and working onsite with government customers to configure, debug, and improve it based on real-world usage. Requires US citizenship, an active DoD TS/SCI clearance, and up to 40% domestic and OCONUS travel.
Software Engineer (Operations Technology & Automation)
Fullstack engineer on a five-person team building the software behind Triumph's physical trading-card business: the vendor portal, inventory dashboard, computer-vision card identification, and warehouse ops tooling. You'll work across a Go backend, React frontend, and React Native mobile apps, on-site in Mountain View (relocating to Fremont, CA).
Controls Software Engineer, Pointing & Tracking
Own the real-time control loop software that keeps lasers precisely pointed between moving satellites and ground stations at Cowboy Space, a startup building space-based solar energy infrastructure. Day to day, you translate control theory into embedded Rust, tune closed-loop controllers, build simulation and HIL test tooling, and support hardware integration through on-orbit operations.
Staff Software Engineer - Security
First dedicated security hire at Flow Engineering, an AI-native requirements platform for hardware/defense teams. You'll own security architecture, harden the full cloud stack, drive SOC 2/ITAR compliance, secure LLM and agentic workflows, and build incident response and security tooling.
Software Engineer
Software engineer at Floqer, a venture-backed startup whose platform lets GTM teams build automations with humans and AI agents. You'll talk to customers, scope and ship features end-to-end, and help scale a cloud/event-driven backend handling 700M+ weekly runs. On-site in Toronto; fluency with AI-assisted dev tools expected.
Staff Software Engineer
A Staff Software Engineer defines and leads core platform architecture at an AI company serving U.S. community banks and credit unions — building agentic/LLM workflows, real-time event systems, and multi-modal APIs with Node.js, Python, and React, while mentoring engineers and working on-site 5 days/week in San Francisco.

Builds high-performance visualization tools (C++/OpenGL, Unity) for Nuro’s autonomous driving tech, enabling engineers to develop and validate autonomy features while collaborating with ML, product, and design teams.
Senior Software Engineer, Collision Avoidance Testing
Develops and executes collision avoidance tests for autonomous vehicles, analyzing real-world and simulated scenarios to improve safety, design test strategies, and quantify risk for Nuro’s Level 4 autonomy platform.
Principal Software Engineer, Onboard Infrastructure
Principal Software Engineer leads the design and development of Nuro’s onboard infrastructure for autonomous vehicles, focusing on hardware-agnostic device interfaces, runtime systems, and distributed execution to ensure high-performance, reliable autonomy software across platforms.
Senior Software Engineer, ML Infrastructure
Builds and maintains the ML infrastructure platform for Nuro’s autonomous vehicle AI, focusing on GPU/CPU resource provisioning, workload orchestration, and petabyte-scale data pipelines to accelerate model development from experimentation to production.
Senior/Staff Software Engineer, ML Infrastructure, Optimization
Builds and optimizes ML infrastructure for Nuro’s autonomous vehicle fleet, focusing on model compression, deployment, and performance improvements (e.g., quantization, distillation) to enhance real-world autonomy.
Software Engineer, ML Infrastructure, Optimization
Builds and optimizes ML infrastructure for Nuro’s autonomous vehicle fleet, focusing on model pipelines, compilers (e.g., FTL), and deployment of optimized models for safe on-road navigation.
Senior/Staff Software Engineer, Connected Systems
Builds the cloud-side Connected Systems platform for Heron Power's grid-connected power electronics: telemetry pipelines, fleet monitoring, fault diagnostics, configuration management, and OTA firmware updates. Work spans edge devices, cloud infrastructure, and backend services, typically in Python, Go, Rust, or Java with Kafka-style event streaming.
Member of Technical Staff, Robotics
Hands-on robotics founding engineer at Reactor, a startup building an AI inference platform for real-time world models. You'll serve robot policies (VLAs, IL/RL) on GPUs under strict latency budgets, build ROS/ROS2 integration and low-latency transport, and debug the full loop from sensors to actions, primarily in C++ and Python.
Software Engineer
An early engineer at SableBio builds the company's AI-enabled toxicology platform for pharma scientists — writing scalable Python applications and data pipelines that ingest and score large biological datasets, collaborating with scientists, and shaping the platform's architecture and engineering culture. Hybrid role based in East London.
ENG: Software Engineer - MENA
Software engineer building the apps and systems behind Delfina Care, a pregnancy-care data platform — web backends, relational databases, data systems, monitoring, mobile apps, and web dashboards. Day-to-day is full-stack feature work in a modern language like Python, TypeScript, or Flutter with testing and cross-functional collaboration.
Founding Software Engineer – React/Python/AWS, Dublin
Searchability is hiring its first dedicated software engineer in Dublin to build a brand-new platform from scratch, reporting directly to the CTO. The engineer owns both frontend and backend using React, Python and AWS, with a strong focus on securing sensitive data in a life sciences AI setting.
Software Engineer
Founding full-stack software engineer (first dedicated hire) at an early-stage AI company in Dublin applying AI to life sciences drug-programme decisions. You build the platform end to end — React front end, Python and AWS back end/data layer — handling sensitive patient and research data, working directly with the CTO. Hybrid, three days a week on site in Dublin.
