Replit is the agentic software creation platform that enables anyone to build applications using natural language. With millions of users worldwide, Replit is democratizing software development by removing traditional barriers to application creation.
The AI Studio is the team responsible for designing, building, and operationalizing internal software platforms across every functional department of the company, including People Operations, Customer Support, Sales, Marketing, Finance, Recruiting, and Executive Operations. We treat each internal department as its own product surface, and in truth as its own startup, with its own customers, its own metrics, and its own reasons for existing. We ship custom software, built on Replit’s own platform, to solve operational problems that off-the-shelf SaaS tools cannot serve well at our scale and pace of growth.
POSITION SUMMARY
The Member of Technical Staff (AI Builder) is a full-time builder role with substantial autonomy. You will design, architect, and ship AI-powered internal platforms that run the operations of the company across many departments at once. This is not a role for someone who wants a narrow, well-defined lane. It is a role for someone who wants to walk into an ambiguous business problem, understand it well enough to argue about it with the department lead, and then ship the software that fixes it.
We are looking for people who genuinely understand the mechanics of a business: how revenue is actually made, why recruiting velocity matters, what makes support scale or break, how finance closes a month, and why each department is critical to whether the company wins or loses. You do not need to have run every function, but you need to respect why each one exists and be able to reason about it like an operator, not just an engineer.
Because we treat each department as its own startup, we strongly favor people who have either run their own business or worked on a fast-scaling startup. You know what it feels like to build with incomplete information, to ship before it is comfortable, and to own an outcome rather than a ticket. The work is genuinely a ton of fun, and it is also demanding: it rewards diplomacy, creativity, technical depth, and business acumen in roughly equal measure. You will move fast, work long hours when it matters, and switch fluidly between a deep technical conversation and a conversation with a non-technical stakeholder who just needs their problem solved.
Design, architect, and ship custom AI-powered internal platforms that serve specific operational needs across Replit’s functional departments, including but not limited to People Operations, Customer Support, Sales, Recruiting, Marketing, Finance, and Executive Operations.
Translate ambiguous, often non-technical business requirements into technical specifications, system architectures, and shipped software products.
Own platform development end-to-end, including front-end interfaces, back-end services, data models, third-party integrations, and AI model orchestration.
Applied AI and Large Language Model Engineering
Architect multi-stage AI pipelines incorporating large language models, including prompt engineering, tool-call architecture, structured output generation, retrieval-augmented generation, and agentic workflows.
Conduct model selection across multiple frontier and open-source providers, evaluating models against cost per query, latency, output quality, reliability, and task-specific performance.
Design and implement evaluation frameworks for AI features, including test datasets, scoring rubrics, and regression tests, so that AI-driven workflows stay reliable in production.
Optimize AI systems for cost and performance, including the appropriate use of lighter-weight models for qualification passes, batching strategies for high-throughput workloads, and caching architectures.
Business Understanding and Stakeholder Partnership
Treat each internal department as its own startup: understand its goals, its constraints, and the metrics that define whether it is succeeding.
Partner directly with department leads to identify operational inefficiencies, scope solutions, and prioritize the work that creates the most leverage.
Conduct stakeholder interviews, lead requirements-gathering sessions, and translate qualitative feedback into iterative product improvements.
Present technical work and operational outcomes to executive leadership, including the President and senior staff, and do it in language each audience can act on.
Third-Party System Integration
Design and implement integrations with the third-party platforms used at Replit, including enterprise HR platforms, support ticketing systems, CRM platforms, applicant tracking systems, project management tools, and identity providers.
Evaluate third-party APIs, SDKs, and data schemas, and design integration architectures appropriate to scale, security, and maintainability requirements.
Production Operations and Reliability
Maintain and operate shipped platforms in production, including dependency management, security updates, observability, error handling, and performance monitoring.
Respond to production incidents and continuously iterate on shipped platforms based on user feedback and operational telemetry.
Documentation and Knowledge Transfer
Document architectural decisions, system designs, and operational procedures for shipped platforms.
Onboard future team members and contribute to the evolution of the AI Studio as the function scales.
דרישות
You understand how a business actually works and can explain why each department matters to the company winning.
You have either run your own business or worked on a fast-scaling startup, and you carry the ownership instinct that comes with it.
You are comfortable with long hours and a very high pace, and you treat that as part of the fun rather than a cost.
You can engage credibly with both deeply technical people and non-technical stakeholders, often in the same afternoon.
You bring diplomacy, creativity, technical knowledge, and business acumen, and you know when each one is the tool the moment calls for.
You would rather ship something real and iterate than wait for perfect information.

Working proficiency in modern software engineering practices, including version control, code review, deployment pipelines, and production debugging.
Hands-on experience with one or more large language model providers and their APIs, tool-calling interfaces, and structured output mechanisms.
Demonstrated experience designing prompt and tool-call architectures, conducting model selection across providers, and optimizing AI systems for cost and latency.
