About Siena

Siena is building enterprise empathic AI Agents powered by reasoning-adept LLMs. Siena is the first AI Agent of its kind, designed to integrate with existing systems and interact with customers across multiple channels from a single, unified platform.

If you're excited about the intersection of human-to-machine communication and want to be part of a team driving innovation and making a real impact in automating agentic workflows, join us on our mission to revolutionize customer experience through empathetic AI.

Some of our values

We're not big on corporate-speak, but here's what matters to us:

  • We put customers first: We work hard to understand our customers. We try to put ourselves in their position and do more than they expect.
  • We're direct and honest: We believe in straightforward, truthful communication. We say what we think, clearly and respectfully.
  • We try new things: We're not afraid to do things differently if it means finding better solutions.
  • We step up: When we see a chance to make a difference, we take it. We trust ourselves to decide and take responsibility for what happens.
  • We're quick on our feet: We adapt to changes and challenges. We see them as chances to learn and grow.
  • We stay curious: We ask questions and explore new ideas. What we learn helps us keep growing.
  • We own it: We're all owners here. We take charge, make the call, and own the outcome.

What you'll be doing:

As a full-stack engineer, you will develop projects end to end. Ownership is yours - take over new and existing product features.

  • You'll contribute with ideas and constructive feedback to the product's development from the roadmap all the way to architecture.
  • You'll develop and collaborate closely with the Product team to slice and dice scope and deliver piece by piece.
  • Building products: 90% of time by building new software products, or improve existing features.
  • Mentorship: you have the ability to mentor and lead other members about 10% of time if you have an appetence for it.
  • Problem-solving: you unblock yourself and other team members when they hit a roadblock.

Join the team if you:

  • 4+ years engineering experience - ideally with NodeJS, Typescript & Express
  • Are familiar with the AWS cloud system. (EKS, ECS, Fargate)
  • Have experience working with Postgres
  • Have experience with CI/CD (GitLab, Github, Jenkins or similar)
  • You are product-focused and have the ability to build products by understanding the business and customers.
  • You have the drive and focus to get challenging projects over the finish line while meeting deadlines.
  • You love solving problems and writing elegant code.
  • You are proud of your microservices architecture skills. But don't like to brag.
  • You thrive in a fast-paced environment.
We're not aiming for expert levels in Node.js, but rather cross-language minded engineers that view and use stacks as problem-solving tools, not the solution.

Impress us even further:

  • You have a high degree of technical knowledge around scaling systems.
  • You have been in a startup from Seed to exit.
  • You have experience working in remote teams.

Why Joins Us

We're a startup. We can't offer you fancy offices or extra perks. But here's what we can offer:

  • Real impact. Your work will directly shape our product and company.
  • A seat at the table. In a small team, every voice matters. Yours will be heard.
  • Freedom to work your way. Home, coffee shop, moon base - if you're productive, we're happy.
  • Top pay. Competitive salary and an opportunity for equity or stock grants.
  • Time off when you need it. Take at least 15 days. More if you need it.
  • Budget to keep learning. Because if you're not growing, we're not growing.
  • The chance to build something from the ground up. This is the time when what you do has the biggest impact.
  • Problems worth solving. We're reshaping how work gets done.

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.
