Senior Site Reliability Engineer (SRE)

At Alternative Payments, we are transforming the way service-based companies handle payments. Our innovative platform automates the entire accounts receivable process, helping businesses save time, reduce costs, and scale with confidence.

We are building a global team that values innovation, impact, and collaboration. As part of a scaling FinTech company, every person on our team has the opportunity to shape our future, influence our products, and make a real difference for our customers.

What We’re Looking For

We’re seeking a Site Reliability Engineer to join our EPD Team and help us drive operational excellence, enhance infrastructure reliability and establish cutting-edge observability across our critical systems.

This role is ideal for someone who thrives on complex technical problem-solving, deep operational ownership, and cross-functional collaboration, and wants to take a hands-on role in shaping our reliability strategy, driving innovation in our infrastructure, and implementing robust SRE practices. You will be joining our team as part of a cross-team DevOps structure.

You will be instrumental in tackling significant challenges currently faced by our platform, such as addressing visibility into system capacity and performance metrics and proactively preventing incidents through enhanced monitoring.

A critical part of your mission will be to fill the end-to-end request traceability and improve our load testing and capacity planning. You'll design and implement automated alerting systems that our Firefighters can confidently rely on, effectively bridging the gap between deep infrastructure knowledge and rapid incident response capabilities.

This role is available to candidates who are eligible to work in Brazil, in a remote setting.

  • Datadog Integration: Continuing the migration back to Datadog and optimizing our monitoring stack.

• Collaborating with cross-functional teams (including our support engineers and DevOps members) to deliver scalable solutions, optimize processes, and implement highly reliable systems.

• Taking ownership of complex SRE tasks, including configuring monitoring systems, defining and enforcing SLIs, SLOs, and SLAs.

• Proposing improvements and helping establish best practices, workflows, and standards for incident response, blameless post-mortems, and continuous improvement.

What You’ll Bring

• 7-10+ years of experience in Site Reliability Engineering, DevOps, or a similar role focused on large-scale distributed systems.

• Strong skills in Kubernetes for container orchestration and cluster management.

• Extensive experience with AWS as a core cloud platform for infrastructure management.

• Critical proficiency with Datadog for monitoring, logging, tracing, and alerting.

• Proven experience in designing, implementing, and optimizing CI/CD pipelines, ideally with GitHub Pipelines.

• Strong understanding and practical application of SRE principles: SLI/SLO/SLA definition, error budget management, incident response, post-mortem analysis, and toil reduction.

• A proactive mindset with the ability to solve complex problems, drive projects independently, and continuously innovate our reliability practices.

• Strong communication skills, especially in English, to collaborate effectively across technical teams and stakeholders.
