Fullstack Software Engineer
role at
Siena AI . Siena is the first intelligence layer for customer experience. 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 with outsized impact. This philosophy makes us faster and more fun to work with. If you\'re excited about building something that doesn\'t exist yet, we\'re building agents that remember customers, learn from every interaction, and connect experiences across channels. About The Role As a fullstack engineer at Siena, you\'ll own projects end-to-end, developing and optimizing features within our AI-powered customer support automation platform. You\'ll work closely with product to shape our roadmap while building reliable, high-performance systems that power millions of monthly customer interactions across global brands.
What You’ll Do
Design, build, and maintain scalable features across the full stack (frontend, backend, and infra).
Collaborate with Product to break down scope into iterative, high-impact releases.
Integrate cutting-edge LLM capabilities into real enterprise workflows.
Work on an AI-first product, integrating LLM capabilities into enterprise customer support workflows.
Solve complex engineering challenges, from optimizing API performance to refining microservices architecture.
Maintain and improve our cloud infrastructure (AWS) with a DevOps mindset.
Exercise ownership—taking initiative, making decisions, and driving ideas to production.
Who You Are
3+ years building in Node.js, React, TypeScript, and Express.
Strong with PostgreSQL, Redis, and cloud environments (AWS: Fargate, Lambda, EC2, SQS).
Familiar with CI/CD (CodePipeline, GitHub Actions, or similar).
Experience with microservices and scalable systems.
Product-driven: you care about the impact of what you ship, not just the code.
AI-first: you are comfortable working with AI tooling and orchestrating coding agents.
Naturally curious and proactive; you don\'t wait for instructions, you create momentum.
Bonus Points
Next.js, Python, or event-driven architectures.
Infra-as-code (Terraform, CDK).
Experience integrating with LLMs in production.
Event-driven architecture experience.
Why Siena?
Meaningful impact. Your work directly shapes our product and company.
Globally distributed team on the cutting edge of CX and AI.
Competitive salary with equity or stock grants.
Learning budget to support growth.
The thrill of building something new where your contributions matter.
AI fluency: make AI a natural part of your work.
Opportunity to tackle unsolved problems in the next decade of customer experience.
Our Values The people who thrive here are curious, customer-obsessed, and take ownership. They fix problems first and explain later. They are direct about feedback and move fast while maintaining high standards. They build real relationships with teammates and adapt when needed.
Our Approach to AI We treat AI as a natural extension of ourselves, building an ecosystem of agents for research, debugging, writing, analysis, and coding. We emphasize sharing knowledge through demo days, Slack threads, and collaborative workflows. We provide premium AI tool access and a quarterly budget for new tools.
At Siena, 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.
