Software Engineer - Agents

About Tensec

Founded in 2023, Tensec is a global fintech that enables small and medium‑sized businesses (SMBs) to enter global trade and thrive by giving them access to user‑friendly, efficient, and secure transaction banking solutions.

We move fast, debrief quickly, and expect you to own your output. This dynamic company values speed and decisiveness over process, giving you the context you need to make good decisions and the autonomy to execute them.

You will own two things simultaneously: the shared agentic infrastructure that makes intelligent workflows possible at Tensec, and the agents and product features that run on top of it. One day you design the context‑management system that every agent depends on; the next you ship an agent that automates a workflow for our operations or treasury team—or a feature that a customer interacts with directly.

This role requires a broad perspective: you must understand the business problems behind the work, not just execute on specs, owning problems end‑to‑end and delivering them to production.

• Design and build the core agentic infrastructure at Tensec: orchestration, tool execution, context and session management, policy controls, and observability.
• Build, ship, and operate agents that automate real financial workflows across operations, compliance, and treasury, from transaction document review to Know‑Your‑Business and sanctions screening.
• Ship product features end‑to‑end, from backend services and APIs to experiences built on top of agentic capabilities, serving both internal and external customers.
• Drive build‑versus‑buy decisions on third‑party components, integrate where it accelerates us, and own reliability and trust matters.
• Build evaluation and monitoring systems to ensure agents are accurate, reliable, and safe in a regulated financial environment.
• Implement routing logic to optimize large‑language‑model usage across providers.
• Contribute to engineering standards, code review, and the technical growth of the team.

• 5+ years of backend software engineering with a track record of shipping production systems end‑to‑end.
• Hands‑on experience building and shipping agentic systems or large‑language‑model‑powered workflows in production.
• Strong product sense: understand business needs, think from the end‑user perspective, and care about whether what you ship creates value.
• Strong fundamentals across APIs, distributed systems, databases, and cloud‑native architecture.
• Comfortable moving between infrastructure thinking and hands‑on product iteration; you don't stay in one lane.
• Comfortable owning ambiguous problems; you can scope, build, ship, and iterate without a lot of hand‑holding.
• Experience in an early‑stage startup or demonstrated ability to work at that pace.
• Node.js or Python backend experience; comfort with AWS and modern CI/CD tooling.
• Experience or genuine interest in regulated industries where correctness and compliance are non‑negotiable.

• Experience with multi‑model or multi‑provider artificial intelligence systems.
• Familiarity with orchestration frameworks, tool use, Model Context Protocol surfaces, or evaluation pipelines.
• Background in cross‑border payments, Anti‑Money Laundering, or transaction monitoring.

• How to build production‑grade AI systems in a compliance‑sensitive financial environment.
• Cross‑border payments and FX infrastructure at scale across Brazil, Mexico, the US, and beyond.
• What it looks like to build a company from the ground up, with real ownership and real stakes.

• The expected salary range for this role is $182,000 – $230,000 per year. Actual compensation will depend on experience, skills, and qualifications.
• Equity.
• Medical, dental and vision.
• 15 days paid time off.
• Learning and development budget.

This role follows a hybrid model. We ask that you be in our Palo Alto office 2–3 days per week.
