Come Make an Impact on Millions of Brazilians!

At RecargaPay, we’re on a mission to deliver the best payment experience for Brazilian consumers and small businesses — by building a powerful digital ecosystem where the banked and unbanked connect, and where consumers and merchants have a one-stop shop for all their financial needs.

We serve over 10 million users and process more than USD 4 billion annually. We’ve been profitable since 2022 and operate our own credit business. We are an AI-first, 100% remote team, scaling in the rapidly changing Brazilian financial market.

Our goal? Deliver the best payment experience in Brazil for people and small businesses alike.

We value autonomy, ownership, and a bias for action. We’re looking for people who are curious, hands-on, and driven by impact — who want to solve real problems, work with strong teams, and rethink what’s possible.

If you’re ready to do your best work, at scale, with purpose — this is your place.

Position Overview

As a Principal DevEx Engineer, your primary mandate is to improve the developer experience end to end, eliminating friction, accelerating onboarding to first contribution, and lifting productivity across the entire software delivery lifecycle. You will still drive modernization and platform initiatives and steward high-leverage practices (DevEx, SRE, DevSecOps, event-driven architectures, and AI-assisted engineering), operating both hands-on and strategically while partnering with executive leadership and guiding Staff / Senior engineers to deliver scalable, reliable, compliant, and cost-efficient solutions on AWS. Crucially, you will translate day-to-day developer needs into golden paths, opinionated tooling, and policy-backed workflows, and you will enable adoption through clear documentation, targeted training, office hours, and lightweight change-management.

Responsibilities

• Define and steer medium- and long-term architectural strategies aligned with company goals.
• Lead technological transformations and modernizations of critical systems, ensuring efficiency, scalability and reliability.
• Serve as the technical authority for the Engineering and Architecture Chapters, championing best practices and quality standards.
• Mentor senior engineers and technical leaders, fostering a culture of technical excellence and continuous learning.
• Promote the adoption of AI-assisted engineering practices within your squad and chapter, leveraging tools for code generation, automated refactoring, test case creation, and technical documentation. Identify opportunities where AI can enhance developer productivity, code quality, and team velocity.
• Codify architecture into practice, delivering reference implementations and golden-path templates that teams can scaffold in minutes.
• Own API governance end to end, with contract-first workflows, OpenAPI / AsyncAPI linting, compatibility rules, schema-registry usage, and large-scale consumer contract testing.
• Institutionalize reliability by defining SLIs and SLOs with teams, establishing error-budget policies, enabling burn-rate alerting, and automating the tracking of post-incident actions.
• Make observability the default through standardized traces, metrics, and logs; consistent span and attribute conventions, dashboards, and log correlation with golden dashboards per service.
• Lead policy-as-code adoption across CI / CD, Kubernetes admission and  IaC.
• Engineer safe delivery with trunk-based flows, reusable GitHub Actions, progressive rollouts (canary / blue-green), automated rollback, and health- or SLO-gated deployments.
• Raise the security bar in services via OAuth2 scopes, JWT validation, mTLS, secrets lifecycle management (Vault / KMS), key rotation, and least-privilege IAM patterns.
• Design event topologies covering Kafka partitioning and keying, compaction and retention policies, consumer-group strategies, ordering and idempotency, and exactly-once semantics where required.
• Drive cost-aware architecture through capacity models, autoscaling policies, storage and egress optimization, cost allocation per service, and cost-to-serve guardrails.
• Harden platform resilience with multi-AZ patterns, backup and restore drills, disaster-recovery objectives (RPO / RTO), chaos / game-day exercises, and dependency fallback strategies.
• Deliver one-click developer environments, using DevContainers / Codespaces, Docker Compose, and seeded data, to reduce onboarding and setup time through standardized tooling and scripts.
• Measure what matters by publishing DevEx and SRE scorecards, setting targets and running continuous improvement cycles with squads.
• Run lightweight technical-governance rhythms, such as design and API clinics, ADR / RFC hygiene, and a platform council to prioritize enablers and eliminate systemic friction.
