Build and refine agent loops that support planning, tool selection, execution, observation, reflection, recovery, and termination. - Model complex workflows as graphs, state machines, or other orchestration patterns that coordinate models, tools, data, systems, and human approvals. - Create evaluation frameworks that measure task completion, accuracy, reliability, safety, latency, cost, and user value. - Develop rapid prototypes and proofs of concept, validate them with real users and representative evaluations, and evolve successful ideas into secure, scalable products. - Integrate solutions with client systems, enterprise data sources, cloud platforms, and third-party services. - Work across the technology stack, contributing wherever needed—from user interfaces and backend services to AI infrastructure, data workflows, and deployment pipelines. - Implement appropriate safeguards, permission boundaries, approval steps, and fallbacks for autonomous and semi-autonomous systems. - Instrument AI applications so teams can inspect traces, understand intermediate states, diagnose failures, and improve system performance. - Identify and address failure modes such as hallucinations, looping, brittle tool calls, context loss, prompt injection, non-deterministic behavior, and unsafe actions. - Troubleshoot complex technical and operational issues in client environments. - Communicate technical decisions, risks, trade-offs, and progress clearly to both technical and non-technical audiences. - Collaborate with product managers, designers, engineers, data specialists, security teams, and client stakeholders throughout the delivery lifecycle. - Establish strong engineering practices, including automated testing, documentation, observability, security, and continuous delivery. - Capture reusable patterns, components, and insights that strengthen TribalScale’s engineering capabilities and future client engagements. - Support technical discovery, solution demonstrations, workshops, and pre-sales conversations when needed. ## What You Bring - Professional experience building and deploying production-grade software, including AI-powered or agentic systems. - Strong proficiency in JavaScript, NodeJS, TypeScript, Python - Strong development fundamentals, object oriented programming, test driven development, and cloud based application deployment - Strong presentation & communication skills, experience working with teams and mentoring other engineers in a collaborative environment - A practical understanding of harness engineering: designing the infrastructure, context, tools, permissions, controls, and feedback mechanisms that enable AI agents to operate reliably. - Experience building or working with agent loops, including planning, tool selection, execution, observation, reflection, recovery, and termination. - Familiarity with graph-based orchestration, state machines, and multi-step workflows for coordinating agents, tools, data, and human approvals. - Experience designing evaluation systems for AI applications, including task-based benchmarks, regression suites, model-graded evaluations, human review, and production monitoring. - Understanding of the trade-offs involved in prompts, context management, memory, retrieval, tool use, structured outputs, and model selection. - Experience instrumenting AI systems to trace decisions, inspect intermediate states, measure quality, and diagnose failures. - Strong knowledge of APIs, distributed systems, databases, cloud infrastructure, and modern software-development practices. - Experience with cloud platforms such as AWS, Microsoft Azure, or Google Cloud. - Ability to quickly understand unfamiliar systems, technologies, and business domains. - Ability to move from an ambiguous customer problem to a working prototype, validate it with real users and evaluations, and evolve it into a secure, maintainable production system. - Strong product judgment and the ability to balance model capability, reliability, latency, cost, security, and user experience. - Experience collaborating directly with customers, stakeholders, or cross-functional delivery teams. - Excellent written and verbal communication skills, including the ability to explain AI-system behavior, limitations, risks, and technical trade-offs clearly. - Comfort working in fast-moving environments where requirements and technical constraints continue to evolve. - A high degree of ownership, curiosity, empathy, and bias toward action. - Ability to travel occasionally for client workshops or on-site delivery, where required. We recognize that strong candidates may not meet every qualification listed.
