Who you are: • Owner. You take responsibility for outcomes, not tasks, and you stay with a problem until it is structurally fixed. • Architect who operates. You design systems and then live with them in production, and that shapes how you design. • Multiplier. You measure your impact by how much faster and better the engineers around you become. • Strategic thinker. You weigh trends, constraints, and business goals to decide what to build, defer, or rework, and you can explain the decision to anyone. • Collaborative and proactive. You build alignment across teams without authority and you bring ideas before being asked. • Works with honesty and integrity. You earn trust with internal and external stakeholders and do what is right, not just what is expedient. You have: • Bachelor of Science in Computer Science, Software Engineering, or equivalent experience. • 10+ years of software engineering experience, including several years at Staff level or above owning production Ruby on Rails and React systems. • Proven ownership of multi-service or multi-team architecture, including integrations with third-party enterprise systems. • Strong operational excellence: observability, on-call, performance, testing, CI/CD, and a habit of designing out recurring failures. • Experience setting standards or patterns adopted beyond your own team, and mentoring engineers to the next level. • Solid command of Postgres, GraphQL, background job pipelines, testing frameworks, and Git. • Fluency with AI-assisted development and the judgment to coach others on it. • Excellent verbal and written communication in English and Portuguese. • Experience working with English environments is preferred. • Previous start-up experience is a plus. • Healthcare, scheduling, or marketplace domain experience is a plus.

The final compensation for this position will vary based on geographic location and candidate experience relative to what reasonably anticipates for this position. We are committed to transparency, and any compensation questions will be addressed early in our recruitment process. First-quarter success By the end of the first quarter, you’ve earned the team’s trust as the person who can unblock hard technical problems and keep the On-Demand platform moving reliably. You’ve clarified the architecture, documented key decisions, improved at least one high-leverage area such as observability, testing, or integration reliability, and helped reduce recurring production issues. Product and engineering are aligned on sequencing and trade-offs, and the team is already working with stronger technical habits, clearer review standards, and better use of AI-assisted workflows. What we need you to tackle We’re looking for a senior technical leader with 10+ years of software engineering experience, including staff-level or higher impact, who has led architecture end to end and can operate hands-on in production. You should have strong Ruby on Rails experience, plus solid React, Postgres, GraphQL, background jobs, observability, testing, and CI/CD skills, ideally in multi-service environments with third-party integrations. The right person is an owner, a clear communicator in English and Portuguese, comfortable challenging assumptions respectfully, and genuinely excited to use AI-assisted development to make the team faster and better.Descrição

About The Role The AI Quality engineering team at Circle owns the foundation for measuring, diagnosing, and improving the quality of Circle's AI-powered features. This team focuses on building the infrastructure to measure, diagnose, and improve production AI systems, rather than ML research or model training. We're looking for a Lead Engineer to help us build out the evaluation frameworks, observability tooling, and diagnostic infrastructure that tell us whether our AI Agents are working well, where to improve them, and how to make them faster and more cost-efficient. This is a hands-on player-coach role. You’ll also lead and manage the AI Quality engineering team, with an ambitious and growing roadmap. If you're excited about making AI systems work reliably, efficiently, and at scale, this is for you. What You'll Be Doing • Build and own our evaluation infrastructure. Design the CI/CD pipelines, scorers, and datasets that tell us whether Circle's AI agents (planners, tool-callers, and sub-agents) are actually working, from a single tool call to a full multi-turn conversation. • Diagnose exactly where quality breaks down. Trace failures across the agent pipeline including plan creation vs. execution, tool selection, tool trajectory in complex areas like workflows, site builder, and analytics. Turn what you find into prototypes that solve the issue or identify priorities for AI core engineering can help. • Grow the datasets that make evaluation possible. Stand up annotation workflows and build out AI-generated and simulated conversations so we can cover more of the product faster than manual labeling alone. • Run structured experiments across prompts, models, and the agent harness. Evaluate new and open-source models against our production baseline, build the framework we use to decide when to shift models, and chase cost and latency wins through model swaps, caching, and routing by plan complexity. • Lead and grow the AI Quality engineering team. Set technical direction and manage day-to-day priorities, all while staying hands-on in the code yourself. • Partner closely with AI Core engineering. Work with the engineers building Circle's AI products so they have real confidence that their changes are actually improving quality, not just shipping. What You'll Need To Be Successful • 7+ years of experience building and shipping production software, ideally including LLM-powered agents that take real actions in a product. You've worked on complex, tool-using systems (multiple tools, planning or orchestration, sub-agents) not just simple, single-turn assistants, and you can walk us through something you shipped and how you knew it was actually working. • Comfortable in Ruby on Rails / Python or ready to pick them up quickly. Ruby on Rails is our production system and the foundation that Circle’s AI Agents are built on and proficiency in Python is a strong plus, especially for the data and evaluation side of the work. • Experience building evaluation or observability infrastructure for ML/AI systems. You've built eval pipelines, scorers, dashboards, or CI/CD for evals before and have experience with evaluation frameworks like Braintrust, LangSmith, or similar. • Experience designing datasets, annotation workflows, or labeling pipelines for ML/AI evaluation. You know how to turn raw examples into a dataset you can trust through human annotation, AI-generated data, or simulation. • Learn fast, experiment aggressively, and thrive in a highly dynamic environment. You’ll need to be comfortable running a lot of experiments and letting the results settle the argument, including the ones that don't work (which will be many of them in the beginning). • Comfortable in a fast-paced environment with ambiguity. You’ll need to learn and pick up new technologies when projects require it. • Strong alignment with our company values. • You are proficient in English (spoken, written, and reading) at a CEFR Level C2 / ILR Level 5. Compensation & Benefits Circle offers U.S.-benchmarked compensation globally, equity in the company with ongoing refresh grants, and 35 days of paid time off each year.
