Mexico

Ready to accelerate your career?
Clara is the fastest-growing company in Latin America. We've built the leading solution for companies to make and manage all their payments. We already help over 20,000 large and growing businesses operate with agility and financial clarity through locally issued corporate cards, bill pay, financing, and a powerful B2B platform built for scale.
Clara is backed by some of the most successful investors in the world, including top regional VCs like monashees, Kaszek, and Canary, and leading global funds like Notable Capital, Coatue, DST Global Partners, ICONIQ Growth, General Catalyst, Citi Ventures, SV Angel, Citius, Endeavor Catalyst, and Goldman Sachs - in addition to dozens of angel investors and local family offices.
We’re building the financial infrastructure that powers high-performing organizations across the region. We invite you to join us if you want to be part of a fast-paced environment that will accelerate your career and support you to do some of the best work of your life alongside a passionate and committed team distributed across the Americas.
What you'll do
We're looking for a Senior Backend Engineer to join Clara's Payments Tribe — We are responsible for powering seamless, secure, and scalable financial transactions across our entire platform.
In this role, you will focus heavily on the engine under the hood. Your primary strength and passion lie in backend architecture, distributed systems, system design, and complex data orchestration. While your core focus is the backend, you possess the frontend competence required to build clean, functional user interfaces, and ensure smooth API consumption on our client-side applications.
AI fluency is central to how we work on this team — you're expected to use it across the full development lifecycle, from design to deployment, and to reach for it whenever it makes you faster or better.
💡 In this role, you will:
Architect Core Infrastructure: Design, build, and maintain highly secure, resilient backend services in Java/Spring Boot that interface with payment processors and local financial networks across Latin America.
Optimize Data & Performance: Ensure high-availability and asynchronous processing of transaction financial data, keeping system latency low and success rates high.
Bridge to the Frontend: Develop and maintain the React-based frontend applications, dashboards, and internal tooling that interact with your backend services, ensuring deep integration and clean API consumption.
Leverage AI: Use AI tools to automate repetitive engineering workflows, accelerate delivery, and close skill gaps — from scaffolding new banking integrations to generating and reviewing code.
Lead & Mentor: Set the technical bar through backend code reviews, robust system design reviews, and hands-on mentorship of junior and mid-level engineers.
Own System Observability: Implement monitoring, logging, and tracing across the full stack to quickly isolate and fail-gracefully when external financial APIs experience downtime.
👤 Who you are
We're looking for an autonomous, systems-minded engineer who loves complex data flows, values strict security, and understands how to deliver clean code from database to browser.
Must haves:
Experience: 5+ years of software engineering experience, with a heavy specialization in Backend/Systems development within a Fullstack or Distributed Systems context.
Backend Mastery (Java / Spring Boot): Strong proficiency in Java and the Spring ecosystem. Deep understanding of relational databases, concurrency, microservices architecture, and building APIs that scale gracefully.
Frontend Competency (React): 2+ years of practical commercial experience with React and its modern ecosystem (Hooks, state management). You don't need to be a CSS pixel-perfect designer, but you must be fully confident in building, structuring, and optimizing responsive web apps.
API & System Integration: Proven experience designing and consuming RESTful and event-driven web services (e.g., Kafka, RabbitMQ).
Testing & CI/CD: Strong practices in TDD, integration testing (JUnit, Mockito), and frontend testing, alongside automated deployment pipelines (GitHub Actions).
AI-Native Mindset: Demonstrated use of AI tools throughout the development process (design, coding, debugging). Experience using tools like Claude, Copilot, Devin, or workflow automation like n8n is highly valued.
Communication: Working proficiency in English and comfort collaborating cross-functionally with Product, Design, and Operations.
Nice to haves / Pluses:
Fintech Domain Knowledge: Prior experience with high-traffic payment gateways, ledger systems, or local financial networks (like Pix in Brazil).
Security & Compliance: Experience handling sensitive financial data (PCI-DSS standards, encryption, tokenization).

Senior Fullstack Engineer — Onboarding
We're looking for a Senior Fullstack Engineer to join Clara's Onboarding team — the team behind one of the most critical moments in the Clara journey: the moment a business decides to trust us. We own the full experience from sign-up to first transaction: KYB and KYC flows, document collection and verification, identity validation, and account activation. The complexity is real — we operate across multiple countries each with its own regulatory framework, and we manage a growing ecosystem of identity and verification providers, each with different APIs, contracts, and data models, that we have to orchestrate seamlessly. Every percentage point of activation we unlock translates directly to Clara's expansion across Latin America.
The role is genuinely fullstack and tends to be backend-heavy — integrations, verification orchestration, data flows — so a backend engineer eager to expand their frontend work will feel right at home. A strong frontend engineer hungry to go deeper on the backend is equally welcome. Either way, you'll own features end to end and work in an environment where AI is central to how we build — from automating manual review steps to accelerating how we expand into new markets.
We move fast and trust our engineers to own outcomes end-to-end. That means autonomy to make decisions, proactivity to surface problems before they become blockers, and the attitude to push initiatives across the finish line without waiting to be told what to do.
Your responsibilities will include:
Designing and building backend services that power the onboarding engine: sign-up, KYB/KYC flows, document collection, verification orchestration, and account activation.
Contributing to the frontend: building intuitive, responsive interfaces that reduce friction at a high-stakes moment for the customer — and that make a complex compliance process feel simple.
Owning integrations with external providers — identity verification, document validation, business data sources — abstracting their complexity behind clean, resilient internal APIs.
Collaborating cross-functionally with Product, Design, Risk, and Compliance to translate regulatory requirements and activation goals into great product experiences.
Applying AI tools to ship faster and improve how the team works
Elevating the team through code reviews, pairing, and sharing what you know with peers
Who you are
5+ years of software engineering experience with solid execution in production environments.
Strong foundation in Java and the Spring ecosystem — Spring, Spring Boot, Spring Batch — for building robust backend services, with genuine appetite to go deeper on the frontend (React) too. A strong React engineer hungry to own the backend is equally welcome.
Comfortable architecting scalable, distributed systems and microservices that hold up under the demands of core financial products.
Solid data modeling instincts, with hands-on experience running PostgreSQL and Redis for both transactional and caching needs.
Experience building and securing RESTful APIs and integrations with third-party providers — comfortable with async and event-driven patterns (Kafka), error handling, and the messiness of external dependencies.
Familiarity with cloud platforms, preferably AWS, and modern dev tooling.
A track record of mentoring engineers and raising the bar on best practices and quality — through code reviews, pairing, and sharing what you know.
English proficiency, with the ability to lead technical discussions across geographies and turn business goals into technical solutions that actually land.
High autonomy and ownership, plus an AI-native approach: you use AI tools actively in your daily work — coding, debugging, automation — and keep pushing further.
We've kept this list short on purpose — these are the things that actually matter. If you check most of these and the rest you'd close with curiosity and the right tools, we want to hear from you.
