Descripción del empleo

Описание

At Tally, we're building a modern accounting platform that helps SMEs spend less time managing their finances and more time running their businesses. Accounting is full of repetitive, manual processes that are difficult to automate reliably. We're changing that by combining AI with solid software engineering practices to handle financial workflows from start to finish. We're tackling complex engineering challenges, from processing financial documents to managing workflows that span weeks. We're building systems that businesses can trust with their finances, where accuracy, reliability, and traceability matter just as much as moving fast.

Задачи

Work across the stack, from backend services and APIs to user-facing experiences. Build AI-powered workflows that handle real accounting tasks, combining LLMs with deterministic logic, validation, and human oversight where needed. Build systems that manage long-running processes, handle failures gracefully, and recover without losing track of what's happened. Extract, process, and reconcile information from invoices, receipts, bank transactions, and other financial documents. Help define our architecture, development practices, and technical direction as the product and team grow.

Требования

Experience designing, building, and maintaining production systems, with a solid understanding of architecture, databases, APIs, and distributed systems. You're comfortable building backend applications in Python. You know when to keep things simple, when to invest in more robust solutions, and how to balance speed with maintainability. You can take a problem from idea to production, make independent decisions, and work closely with both technical and non-technical teammates. You're curious about building software with LLMs and agentic workflows. Будет плюсом: Experience with Django and PostgreSQL is a plus; Hands-on experience is a strong plus, but not required; Experience with these technologies is a plus, but strong engineering fundamentals matter more

Условия

This is an in-office position, 5 days a week, in Lisbon. We believe great early-stage teams are built in the same room. Our product is still early. Some things are rough, and there's plenty to figure out. That's part of the opportunity to make a real impact. You'll wear multiple hats, work beyond your usual responsibilities, and help wherever you're needed. That won't change anytime soon. We expect you to use AI tools to move faster, experiment, and focus on what matters. What counts is the quality of what you build, not how many lines of code you write.
