Tech Lead – Martech

Tech Lead — MarTech

MarTech is the team at Clara that owns user acquisition — the step right before onboarding. Our focus is bringing in the right businesses — the ones that are a real fit for Clara and go on to become active customers. We build the systems behind that — from acquisition surfaces and attribution to lead qualification — across multiple Latin American countries.

We're looking for a Tech Lead to be the senior technical voice of this team from day one. This is a hands-on Builder role, not a people-management one: career conversations and performance reviews belong to a Director, so you can stay fully focused on the technical bar. You lead by building — your PRs, architecture docs, and reviews are what the team calibrates to. You'll set the technical direction across the stack and work hand in hand with product on what's worth building and why. You'll also shape how the team works: its architecture, its standards, and its execution rhythm.

We move fast and trust our leads 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:

• Owning architecture and system design for MarTech's systems, and staying hands-on writing code across backend and frontend
• Building the foundation for user acquisition — tracking and attribution, lead capture and qualification, and the integrations with our ad, CRM, and marketing platforms — so we bring in businesses that go on to activate, not just volume
• Owning the team's execution rhythm — sprint planning, standups, backlog grooming, retros — and being accountable for velocity: PR cycle time, deploy frequency, and healthy WIP
• Setting and holding engineering excellence — code review standards, test coverage, and proactive management of technical debt
• Unblocking the team day to day through code reviews, design reviews, pairing, and debugging
• Owning product specs from the technical lens — reviewing them before work starts, flagging feasibility gaps and complexity, and spotting where AI tooling can close work that would otherwise take months
• Owning system health for the services you own: security posture, data privacy, scalability, performance, and availability
• Driving cross-team problem-solving and architectural discussions with Product, Marketing, Data, and Onboarding

Who you are

• 7+ years of software engineering experience, with time spent as the senior technical voice on a team (formally or informally)
• A hands-on Builder who sets the standard through your own PRs, architecture docs, and reviews
• Full-stack engineering with your strength on the backend. We work primarily in Java and Spring on the backend and React on the frontend — depth in those is a plus, but we care more about strong fundamentals and how fast you ramp than about years in any one stack
• Strong understanding of microservices architecture and event-driven systems using Kafka. Experience with acquisition systems — ad platforms, tracking and attribution, CRM, funnels and experiments — is a strong plus
• A technical product mindset. You read the roadmap, not just the sprint. You go to product conversations with proposals, not just estimates
• The most fluent AI user in the room — you model AI-native engineering day to day and actively find where AI tooling closes product gaps. At Clara, AI is part of how we work, not a side topic
• High autonomy and ownership, plus English proficiency to lead technical discussions across geographies

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.
