Headquartered in New York, with offices in Tel Aviv and London, we are backed by top investors, including Aleph, Third Point Ventures, Greycroft, StepStone Group, as well as leading global CFOs and accounting firms.

As our company grows, an exciting opportunity awaits a dynamic individual to join our R&D team. We seek an experienced Full Stack Team Lead who wants to join our core team and help us build the single source of truth for the financial world.

As Trullion accelerates into its next stage of growth, we're opening a high-impact engineering leadership role to spearhead the evolution of Trulli- our AI-powered knowledge and analysis agent. Trulli is at the center of our product ecosystem, combining advanced Retrieval-Augmented Generation (RAG), deep product understanding, and intuitive UX to help accounting, finance, and audit teams search, interpret, and act on complex data with speed and confidence.

• Lead, mentor, and grow a multidisciplinary engineering team (backend, frontend, and AI), fostering strong execution, technical excellence, and a culture of ownership.
• Own Trulli's technical roadmap and architecture, driving decisions that ensure scalability, low latency, reliability, and long-term system health.
• Shape and evolve Trulli's AI foundation, including RAG pipelines, retrieval systems, vector databases, and LLM integrations to improve accuracy and end-user trust.
• Drive the adoption of MCP and agent-based architectures, expanding Trulli's capabilities around workflow automation, orchestration, and intelligent reasoning.
• Lead end-to-end feature delivery, transforming product requirements into production-quality solutions with clear milestones and high velocity.
• Establish engineering best practices- code quality, testing strategy, observability, performance, and CI/CD, ensuring fast iteration without compromising stability.
• Partner closely with Product to shape scope, break down complex initiatives, plan sprints, and deliver high-impact releases on time.
• Collaborate across R&D- align architecture, share frameworks and infrastructure, and ensure Trulli fits seamlessly into the broader Trullion ecosystem.
• Act as a hands-on technical leader, providing guidance on complex design decisions, reviewing code, and unblocking engineers when needed.

• 6+ years of software engineering experience, with strong backend expertise in Python and experience designing production-grade services.
• 2+ years leading engineers or managing a development team, ideally in a fast-paced, product-driven environment.
• Hands-on modern frontend experience (React or equivalent), comfortable contributing to full-stack development when needed.
• Experience building or maintaining scalable, distributed systems (microservices, cloud-native environments, async processing, etc.).
• Familiarity with AI-driven development, such as working with RAG components, vector databases, embeddings, or frameworks like LangChain or LlamaIndex.
• Strong communication and cross-functional collaboration skills, with the ability to simplify complexity and influence without authority.
• Balance of leadership and hands-on capabilities, maintaining technical depth while guiding the team at a strategic level.

A Strong Advantage

• Deep experience with RAG architectures, retrieval systems, and LLM-based applications.
• Knowledge of Kubernetes, Docker, and cloud infrastructure (AWS/GCP).
• Background in startup or scale-up environments, comfortable navigating ambiguity and driving clarity.
• Experience building tools for technical users, data-intensive workflows, or B2B SaaS products.

We embrace our core values in everything that we do:

• Think BIG. We are ambitious, proactive, and we love challenging the status quo.
• We live by truth. We uphold the highest standards of accuracy and accountability.
• On Your Side. We are on this journey together and want to collaborate and empower each other to succeed.
• Committed. Committed to execution. Committed to delivery. Committed to excellence.
