Who are we?

We are a cloud-native solutions company focused on helping businesses build secure, compliant, and scalable platforms in the cloud. Over time, we’ve grown into a mature and experienced team, trusted by tech companies — from startups to established enterprises — to design, build, and operate critical infrastructure, data platforms, and modern applications that support their growth.

Our mission is to enable companies to succeed in the cloud by delivering robust, modern solutions that combine Software Engineering, Cloud, DevOps, and Data Engineering practices. We take care of the complexity behind cloud infrastructure, platform security, automation, applications, and data pipelines, so our clients can focus on what they do best — running and growing their business.

We are looking for curious, driven, and committed Software Engineers who are eager to grow and solve real-world problems. People who enjoy working in teams, love a challenge, and are passionate about building reliable, scalable, and secure solutions.

Our teams work closely with clients to solve complex business and technical problems, designing and delivering well-architected, modern applications and platforms. We value hands-on engineers who are excited to build, automate, and improve — and who share our enthusiasm for software craftsmanship, DevOps culture, and modern engineering practices.

We are a distributed company, and we excel at having great communication — your challenge is to be at the same level as your teammates.

You’ll work on interesting and diverse technical challenges, helping to build applications and platforms that our clients rely on to run their businesses. We expect you to be curious, proactive, and ready to dive deep into complex problems. You’ll collaborate with others to turn ideas into reality, bring your own perspective to the table, and help shape solutions that are secure, scalable, and maintainable.

• Stabilize and support a large-scale production platform during a growth stage.
• Work closely with data and cloud engineering teams to identify, debug, and resolve issues in production.

Job description

Somos a Árvore, a plataforma gamificada de aprendizagem que semeia o prazer em aprender.

Na Árvore, acreditamos que a leitura é um superpoder que facilita o aprendizado, ajuda no entendimento do mundo e potencializa as habilidades do século XXI.

Trabalhamos todos os dias para que cada vez mais alunos tenham acesso à leitura. Atualmente, já impactamos mais de quatro milhões de alunos, e sabemos que podemos ir ainda mais longe.

Tecnologia e inovação fazem parte das nossas raízes. Jogamos junto com escolas e famílias no desafio de educar em um dia a dia ultraconectado.

Somos plurais e empáticos, nos adaptamos e encaramos os desafios do futuro com curiosidade e entusiasmo. Somos apaixonados por nossos clientes e comprometidos com resultados e entregas melhores todos os dias.

Com as nossas soluções, somos vencedores há 9 anos seguidos do prêmio Top Educação e a 1ª startup brasileira a vencer o GESAwards, a maior competição de Edtechs do mundo.

Aqui você vai encontrar um ambiente de crescimento, dinâmico e com aprendizados constantes. Esse desafio faz sentido para você? Vem pra Árvore.

Como Software engineer , você vai integrar um squad multidisciplinar com o objetivo de desenvolver soluções técnicas de ponta a ponta, desde as primeiras conversas com os times de produto e design até o monitoramento da funcionalidade em produção. Sua missão será entregar novas funcionalidades e melhorias na nossa plataforma, mantendo o padrão de qualidade técnica e subindo a barra quando possível. Valorizamos a autonomia e a proatividade, pois acreditamos que essas características são fundamentais para o bom funcionamento dos nossos times e da nossa engenharia. Prezamos pessoas antes de processos.

Alguns exemplos de desafios técnicos que você pode encontrar no seu dia-a-dia aqui:

• Implementar mudanças de escalabilidade para suportar cada vez mais usuários (+300 mil usuários ativos por dia).
• Desenhar uma plataforma genérica de gamificação dos nossos produtos.
• Refatoração do sistema de usuários e grupos para melhor atender novos requisitos.
• Desenhar mudanças na plataforma para ela ser mais genérica quanto ao tipo de conteúdo (ex: artigos, notícias…).
• Implementar novas funcionalidades que ajudem nossos usuários a lerem mais livros.
• Implantar testes que nos ajudem a entender o comportamento de nossos usuários.
• Nos ajudar a quebrar nosso monolito em partes menores e mais modulares.

Além dos desafios técnicos, também esperamos que você ajude a elevar a qualidade técnica da equipe e do nosso código, através de:

• Reviews de código.
• Mentoria de seus colegas.
• Identificação de problemas e melhorias nos nossos códigos e sistemas.
• Proatividade para implementar melhorias nos nossos sistemas.
• Colaboração de conhecimento através de discussões síncronas ou assíncronas.

Quanto à nossa stack, ela é centrada em Elixir e no framework Phoenix , com GraphQL fazendo a comunicação entre o backend e o frontend. Nossos frontends são em React/React Native. Para pessoas mais focadas no frontend, espera-se que também toque faça mudanças pequenas no backend também e para quem tem mais bagagem no backend, espera-se que consigam fazer funcionalidades básicas no frontend.

No nosso backend seguimos o paradigma funcional e as diretrizes do Elixir e do Phoenix . Mas se não tiver experiência com a linguagem não tem problema, você vai conseguir aprender tudo aqui com a gente. Normalmente nos primeiros dias a pessoa já consegue abrir PRs e em até 3 meses ela já se sente confortável em codar em Elixir.

• Processamento assíncrono através de background jobs e/ou mensageria;
• Experiência com aplicações que usam Cloud (ex: AWS, RDS, S3);

Seria legal que você tivesse também:

• Experiência com monitoramento e observabilidade de sistemas;
• Conhecimento avançado de monitoramento e observabilidade das soluções.
