Software Engineer, Agentic Applications

Where multiple locations are listed for this role, the position may be based in any of those locations, with priority determined according to the order of listing.

Our cross-platform desktop client is the main way users experience Simular’s AI agents. It looks like a chat interface at first, but behind it is symbolic code generation, debugging tools, execution panels, and more. We want this to feel as intuitive and elegant as the best productivity apps.

We’re looking for a frontend/application engineer with taste - someone who cares about design, simplicity, and user experience, not just pixels or code. You’ll be building the surfaces users live in every day, and what you ship may often be the design.

What you’ll do

• Own and evolve our cross-platform desktop app and future client experiences.

Design and implement intuitive, elegant UX for interacting with AI agents, editing code, and managing tasks.

• Explore new interaction patterns that make powerful AI tools feel simple and natural.

• Work across layers: from user-facing UI to system integrations with native APIs when needed.

• Potentially extend to mobile or web apps in the future.

Own your slice end-to-end: not just UI but also business logic, BFF APIs, even backend pieces when needed.

You might be a fit if

• You can build beautiful, functional apps and you care deeply about UX.

• You have experience with some of: desktop frameworks, web/mobile, or native APIs - but you’re not limited to one stack.

• You’ve built things outside of work (personal projects, side apps) that show taste and ownership.

• You’re excited by both design details and technical depth.

• Bonus: portfolio of design-forward apps, experience bridging web/native, or prior work on developer tools/productivity software.
