Senior Software Engineer, AI Voice Agent
As a Senior Software Engineer on the AI Voice Agent team, you will work on real-time systems involving live audio streaming and latency optimization integrated with speech providers. You will build and improve conversation intelligence systems that manage LLM layers, including prompt construction, context management, function calling, and dialogue management to create natural, actionable phone conversations. You will develop the action framework allowing configurable API calls with branching logic and runtime execution, supporting tasks like data lookup and ticket creation during calls. You'll manage knowledge ingestion, storage, and retrieval to enhance agent memory and learning over time. You will collaborate with designers to enable customers to create, configure, test, and deploy voice agents through intuitive product experiences. Additionally, you will help develop evaluation frameworks, analytics, call quality metrics, and monitoring instrumentation, and participate in on-call rotation duties.
Member of Technical Staff (Data): World Models
Design, automate, maintain, and optimize Python ETL pipelines (Spark/Ray) for large-scale multimodal data. Build and maintain data cataloging, lineage, quality tooling, integrity verification, access controls, and lifecycle management systems. Provide guidance, internal tools, and documentation to colleagues on data best practices. Serve as a custodian of the company’s datasets, ensuring overall data health, quality, and discoverability.
Forward Deployed Engineer - Sydney
Forward Deployed Engineers lead complex end-to-end deployments of frontier models in production alongside strategic customers, owning discovery, technical scoping, system design, build, and production rollout while partnering with customer engineering and domain teams. They own technical delivery across multiple deployments from prototype to stable production, build full-stack systems to deliver customer value, embed closely with customer teams to understand needs and guide adoption, scope work, sequence delivery, and remove blockers early. They make trade-offs between scope, speed, and quality, contribute directly in the code when needed, codify working patterns into reusable tools and playbooks, share field feedback to help Research and Product improve models, and keep teams moving through clarity and follow-through.
Freelance Junior Journalist - AI Trainer
As an AI Trainer - Junior Journalist, the responsibilities involve training AI models by crafting text that teaches AI reasoning, logic accuracy, nuance, and clarity. Contributors may craft original, clear, and fact-checked responses based on project guidelines, generate prompts that challenge AI, define comprehensive scoring criteria to evaluate the accuracy of AI's answers, and follow style and quality standards to ensure consistency.
Machine Learning Developer (Freelance)
Contributors may design original computational STEM problems simulating real scientific workflows, create computationally intensive problems requiring Python programming to solve, develop problems requiring non-trivial reasoning and creative problem-solving, verify solutions using Python with standard libraries such as Numpy, Pandas, Scipy, and scikit-learn, and document problem statements clearly with verified correct answers.
Statistics & Python Expert - Freelance AI Trainer
Contributors may design original computational statistics problems that simulate real mathematical research workflows, create problems requiring Python programming to solve using libraries like Numpy, SciPy, and Sympy, ensure problems are computationally intensive and cannot be solved manually within reasonable timeframes, develop problems requiring non-trivial reasoning chains in areas such as number theory, combinatorics, graph theory, and numerical analysis, base problems on real research challenges or practical applications from mathematical practice, verify solutions using Python with standard mathematical libraries, and document problem statements clearly while providing verified correct answers.
Energy Systems Engineer - Freelance AI Trainer
Contributors may design rigorous energy engineering problems reflecting professional practice, evaluate AI solutions for correctness, assumptions, and constraints, validate calculations or simulations using Python (NumPy, Pandas, SciPy), improve AI reasoning to align with industry-standard logic, and apply structured scoring criteria to multi-step problems.
