Role Description Aqui, Product Engineer não é a pessoa que recebe ticket e entrega código. É alguém que assume responsabilidade por um problema de produto de ponta a ponta. - Você vai atuar em um trio autônomo com PM e designer. - O time tem missão clara, indicadores definidos e autonomia para decidir caminhos. - Participar da construção da solução desde o início, ajudando a definir specs, entendendo contexto e influenciando decisões. - Mais do que entregar features, acompanhar adoção, ler dados, investigar impacto e propor as próximas iterações. - A principal pergunta que guia o trabalho não é “o que precisa ser feito?”, mas sim: “isso realmente move o indicador que importa?” O que você vai construir: - Fluxos autônomos que eliminam tarefas manuais de recruiters, como triagem, agendamento e geração de pareceres. - Integrações críticas que destravam operações de grandes empresas. - Instrumentação e métricas que ajudam a entender se o que construímos está sendo usado e gerando impacto. Você vai trabalhar em um produto que impacta diretamente a rotina de mais de 120 mil profissionais de RH no Brasil. Qualifications - Node.js e TypeScript no backend: código limpo, sustentável e fácil de evoluir. - React no frontend: entendimento de component design e experiência do usuário para construir interfaces bem resolvidas. - DynamoDB, ClickHouse ou bancos similares: capacidade de modelar dados pensando em escala e performance. - Arquitetura de microsserviços: clareza sobre responsabilidades e limites entre serviços. - AWS (Lambda, Serverless, SQS): experiência prática com deploy, monitoramento e debugging em produção. - Integração com LLMs (OpenAI, Claude, etc.): já ter explorado ou colocado soluções em produção é um diferencial importante. Requirements - Consegue analisar dados de uso e transformar insights em hipóteses. - Questiona requisitos quando necessário e busca entender o “porquê” antes de implementar. - Faz estimativas com responsabilidade e previsibilidade. - Documenta decisões técnicas de forma clara para diferentes áreas do time. Profile - Trabalha com velocidade sem perder transparência sobre riscos e problemas. - Tem senso crítico, argumenta bem e contribui para discussões de forma construtiva. - Se sente confortável em ambientes com ambiguidade e autonomia. - Entende contexto e adapta soluções de acordo com diferentes perfis de cliente. Differential - Experiência prévia com ATS, RH Tech ou produtos para RH. Stack - Node.js - TypeScript - React - DynamoDB - ClickHouse - Typesense - AWS (Lambda, SQS, S3) - Microsserviços - LLMs (Claude, OpenAI) How We Work - 100% remoto, com equipe distribuída pelo Brasil e sede em Salvador. - Times pequenos com autonomia real. - Ciclos curtos de construção: planejamos, construímos, medimos e iteramos rapidamente. What We Offer - Plano de saúde Amil. - Gympass ou Total Pass. - Day off no dia do seu aniversário. - BemEstar (teleconsultas mensais com psicólogos, nutricionistas, médicos, etc). - Licenças maternidade e paternidade estendidas. - Descanso remunerado (30 dias por ano). - Modelo de contratação 100% Remoto, Modelo PJ.
