Descrição da vaga

Job Description Full-TimeRemote 10.000 USDEmpowers the healthcare workforce with technology-first solutions to optimize the clinical workforce. By combining our AI-powered staffing platform with dynamic labor marketplaces, we help leading employers automate the matching and fulfillment of clinical staff---driving down labor costs and reducing administrative burden. Our mission, to help people everywhere get care, has support from top institutional investors such as Craft Ventures, Felicis Ventures, Stepstone, and Founder Collective as well as healthcare innovators like Texas Medical Center, Mercy Health, Intermountain Ventures, and Town Hall Ventures.

What we are looking for:

We are looking for a Staff or Principal Software Engineer to lead the engineering of our On-Demand module, the part of the Works platform that lets hospitals fill open shifts with their own workforce. You will own the module end to end, from ingesting demand out of hospital workforce-management systems through shift matching, incentive pricing, and the mobile experience nurses use to claim shifts, and you will work as a pair with the On-Demand Product Manager to shape what we build and why.

Your responsibilities:

• Own the architecture, technical roadmap, and operational health of the On-Demand module: demand ingestion from UKG and ShiftWizard, shift gaps and matching, claim eligibility, incentive pricing, FTE attainment, timecard audits, and the GraphQL API used by web and mobile.
• Pair with the On-Demand Product Manager on discovery, roadmap, and trade-offs, bringing an engineering perspective on cost, risk, and sequencing.
• Lead design reviews and write architecture decision records; ensure architecture consistency across the pod and with neighboring teams.
• Deliver platform improvements (observability, testing strategy, CI/CD, data pipelines, integration frameworks) that make other squads more productive.
• Design out recurring production failures; own the hardest on-call and production issues and set up alerting before issues reach customers.
• Mentor engineers in the pod, raise the bar in code review, and grow the next generation of senior engineers.
• Approach all engineering work with a security and data-protection lens appropriate to healthcare data.
• Use AI-assisted development fluently and coach the team on responsible, high-judgment use.
• Communicate clearly and proactively with engineering, product, business, and leadership.

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. Previous start-up experience is a plus. Experience working with US companies is preferred.

We offer:

• Competitive compensation in Brazil
• Stock options
• CLT Hiring
• Bradesco Nacional health plan
• Life insurance fully paid for by the company
• Investment of R$1.000,00 to equip your home office
• Food or meal voucher of R$33,00/day
• Home office assistance in the amount of R$250,00/month
• We send a laptop and some peripheral devices
• Reasonably anticipates the below to be the monthly base salary range for this role. 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.
