Full Stack Software Engineer

About the role

About us:

Calder is solving the data bottleneck for embodied AI and world models. Today's AI models lack the real-world, 4D data needed to reason on spatial problems and operate in physical environments. We capture, process, and deliver high-fidelity human-generated spatial data at scale, providing the substrate that trains the next generation of generalizable models for manipulation, navigation, and interaction.

ABOUT THE ROLE

We're looking for a Full-Stack Engineer to build the apps, tools, and websites that run Calder's operations. A lot of the business depends on software someone has to build quickly: dashboards that show managers where collection, QA, and deliveries stand; internal tools that replace spreadsheets and one-off scripts for operations and review teams; and portals that let vendors and customers onboard, upload, track status, and get what they need without a support thread. You'll take requests directly from leads managers, operators, vendors, and customers, turn them into a clear scope, and ship them end to end — frontend, backend, data, and deployment. This is a hands-on, high-ownership role: you will talk to the people who have the problem, ship a first version fast, and keep improving it based on how it is actually used.

- Build and own dashboards for managers and leadership — collection progress, QA and review throughput, vendor performance, delivery status — backed by queries you can trust over our databases and data lake

- Build internal tools for operations and review teams: task queues, review UIs, admin consoles, bulk-edit and correction tools, and lookups that replace spreadsheets and ad-hoc scripts

- Build vendor-facing apps: onboarding, large-file upload and intake, metadata capture, equipment and location management, status tracking, and feedback loops so vendors can fix issues themselves

- Build customer-facing apps and sites: delivery portals, dataset browsing and previews, delivery dashboards, and reports shaped to each customer's requirements

- Gather requirements directly from managers, ops leads, vendors, and customers; turn vague asks into a scoped first version, and iterate quickly once it ships

- Design the backend behind those tools: APIs, Postgres schemas and migrations, and integrations with our data pipelines, storage, and third-party services

- Own access for external users — organizations, SSO, roles and scopes — so each vendor and customer sees exactly their own data and nothing else

- Ship with tests (unit, integration, end-to-end), CI/CD, and monitoring, and support what you run in production

- Keep a consistent component and design system across internal and external apps so new tools are fast to build and easy to use

- Write short docs and runbooks so ops and support can use and troubleshoot the tools without tribal knowledge

ABOUT YOU

- 4+ years building and shipping production web applications end to end — frontend, backend, database, and deployment
