Senior Fullstack Engineer (Ingeniero/a de Software Fullstack Senior) - Remote

Ready to accelerate your career?

What you'll do

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

We’re looking for someone who meets the minimum requirements to be considered for the role. The preferred qualifications are a bonus, not a requirement.

Must haves

• 5+ years of software engineering experience with solid execution in production environments.

• Strong foundation in either Java (backend) or React (frontend), and a genuine appetite to work on both sides of the stack.

• Experience building integrations with third-party APIs — comfortable with async patterns, error handling, and the messiness of external dependencies.

• Familiarity with cloud platforms, preferably AWS, and modern CI/CD and Github workflows.

• Working proficiency in English and Spanish.

• Experience or interest in AI tools to automate workflows and optimize code.

• Excellent verbal and written communication, with the ability to lead technical discussions across geographies.

• Adaptability to fast-changing environments and a high degree of ownership over outcomes.

Nice to haves

• Independent analytical skills using spreadsheets, SQL, or Python.

• Experience handling data infrastructure or monitoring via tools like Databricks or Metabase.

• A good sense of humor.

Clara’s Hybrid Policy

Claridians in a hybrid mode split their time between working from the office, talking to or visiting customers, or working from home. This hits a balance between bringing people together for in-person collaboration and learning from each other, while supporting flexibility about how to do this in a way that makes sense for each individual and team.

We don't enforce a minimum number of days for most roles, but you're expected to spend time at the office organically, and be at the office most days during your ramp-up or when required by your leader.
