We're creating an operating system of AI agents that learn, remember, and act across every customer touchpoint—from support conversations to shopping experiences to voice and social media interactions. Siena doesn't just automate support; it powers shopping agents, builds persistent customer memory, generates actionable business insights, and creates empathetic interactions that feel human. We're transforming how businesses understand and connect with their customers, turning every interaction into intelligence that makes the next one better. The team We're a small, distributed team that punches way above our weight. Every person here has outsized impact because we've built leverage into everything we do. This philosophy makes us faster and, frankly, more fun to work with. If you're excited about building something that doesn't exist yet, keep reading—we're building agents that don't just respond to customers—they remember them, learn from every interaction, and connect experiences across channels. About The Role We're on the lookout for an AI Engineer to join our growing AI team. Your mission will be to use the power of Large Language Models (LLMs) and other AI technologies to elevate the capabilities of Siena AI's products. This role is for someone who loves exploring the edges of what's possible with ML technology and applying these innovations in practical, impactful ways. What You’ll Achieve Lead the development and experimentation of new AI features. Successfully integrate and deploy new AI technologies into our core product, enhancing our customer service solutions. Work closely with cross‑functional teams to ensure timely delivery of AI‑driven product features. Keep abreast of the latest developments in AI, especially in LLMs, to ensure Siena AI remains at the cutting edge. Skills You’ll Need to Bring Expertise and Curiosity: you have substantial experience (3+ years) in building AI products using LLMs, embeddings, or other ML natural language technologies. You're eager to share your knowledge while remaining open to continual learning and exploration. Holistic Problem‑Solving: your approach to challenges is comprehensive, considering the broader impact of your solutions. You excel at converting complex problems into elegant, business‑oriented solutions. Empathetic Leadership and Communication: you're skilled in conveying intricate technical ideas clearly and collaborating effectively with both engineering peers and non‑technical team members. User‑Centric and Impact‑Oriented: you prioritize projects based on their business impact and are attuned to how your work affects real people's lives. Nice to Haves Familiarity with our tech stack (React, TypeScript, Node.js, Postgres) or similar technologies. Experience with data pipeline technologies like Spark, DBT, etc. A broad understanding of system architecture, from user interfaces to data models. Interest or background in fields outside of technology, reflecting our belief in the value of diverse perspectives. Join Our Team At Siena AI, we're looking for talented individuals from various backgrounds to reflect the diversity of our global customer base. If you're passionate about AI and eager to contribute to a team that's making a real difference, we'd love to hear from you, even if your experience doesn't perfectly match every point in this description. Why Siena? Meaningful impact. Your work directly shapes our product and company. Globally distributed team working at the bleeding edge of CX and AI. Great salary plus the opportunity for equity or stock grants. Learning budget. If you're growing, so are we. The thrill of building something new. Join us at a stage where your contributions matter most. AI‑fluency. Make AI your second nature. Tackle unsolved problems. We’re redefining how customer experience will look like in the next decades. Our values The people who thrive here are curious, customer‑obsessed, and take ownership without being asked. They fix problems first and explain later. They're direct about feedback—both giving and receiving it—because they care more about getting things right than being polite. They maintain high standards while moving at startup speed, and they build real relationships with teammates because they know that's how great work gets done. When things get tough, they adapt and keep pushing forward. Our approach to AI The people who thrive here treat AI like a natural extension of themselves. They've built their own ecosystem of agents—some for research, others for debugging, writing, analysis, or writing code. They know which AI works best for what problem. Everyone gets premium accounts (ChatGPT, Claude, Perplexity Pro, Cursor, Lovable) plus a quarterly budget for new tools. But the magic happens in how we share knowledge. Demo days where someone shows off clever workflows. Slack threads about which model handles a specific use case better. Learning from each other's AI workflows. At Siena, we’re not just looking for people who can do a job. We’re looking for people who want to break boundaries, create the future, and reshape industries. If that’s you, we look forward to your application. Siena provides equal employment opportunities to all employees and applicants for employment without regard to race, color, religion, sex, national origin, age, disability, genetics, sexual orientation, gender identity, or gender expression.
