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.

Freelance Junior Journalist - AI Trainer
As an AI Trainer - Junior Journalist, the role involves helping to train 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 to challenge AI, define comprehensive scoring criteria to evaluate AI answer accuracy, and follow style and quality standards to ensure consistency.
Machine Learning Developer (Freelance)
Contributors may design original computational STEM problems that simulate real scientific workflows, create problems that require Python programming to solve, ensure problems are computationally intensive and cannot be solved manually within reasonable timeframes, develop problems requiring non-trivial reasoning chains and creative problem-solving approaches, verify solutions using Python with standard libraries such as Numpy, Pandas, Scipy, and scikit-learn, and document problem statements clearly while providing verified correct answers.
Senior Software Engineer – Applied AI for Corporate Systems
The Senior Software Engineer is responsible for partnering with Finance and HR stakeholders to map, document, and prioritize workflows that can be automated with AI agents, building autonomous and semi-autonomous agent workflows that interact with browsers, internal APIs, ERP systems like NetSuite, and HRIS platforms such as BambooHR. They design and operate Model Context Protocol (MCP) Servers callable by AI Agents to act on corporate systems, and build proprietary agent libraries, prompting strategies, and benchmarking frameworks tailored to corporate use cases. The role includes developing and maintaining integrations between AI agents and corporate SaaS platforms including NetSuite, Slack, and Google Workspace, developing custom JavaScript (SuiteScript) for NetSuite to automate workflows and integrations, prototyping, testing, and optimizing AI-powered applications including workflow automation for Finance and HR. The engineer translates complex business processes such as month-end close, payroll, onboarding, and compliance reporting into clear technical specifications, provides technical documentation and training to non-technical Finance and HR teams for adoption of AI solutions, participates in architecture reviews, sprint planning, and cross-functional alignment with Finance, HR, Legal, and Engineering teams, and stays current on advancements in AI technologies while evangelizing AI capabilities internally across Aircall.
