Database Engineer

• Own meaningful parts of the backend
• Scope, design, ship, and stabilize the services the rest of the product depends on. Own the fix when something misbehaves at 2am.
• Make the architectural calls — data model evolution, caching boundaries, where to spend latency budget, when to refactor and when to rewrite.
• Work fluidly across the data layer. Relational stores at scale (MySQL, MariaDB) and document stores (Firestore) are both in the toolkit, and you know which to reach for and when.
• Treat infrastructure as code as part of the job. Terraform and Ansible aren’t someone else’s problem; a service isn’t shipped until it can be re-deployed without you in the room.
• Treat performance, observability, and operational health as part of “done.” Dashboards and alerts ship with the feature.
• Move across the stack when the work demands it
• Open TypeScript PRs in the Electron app when a feature is better wired end-to-end than handed off. You’re comfortable on both sides of the boundary.
• Have opinions on UX workflows and product surfaces, not just API shapes. The best backend engineers we’ve worked with care how the thing feels.
• Get into the Electron app, the overlay, or the web surface when that’s where the bug actually is.
• Drive the backend roadmap
• Take ownership of what we work on, what we cut, and what we sequence. The Head of Engineering will partner closely early on; the bar is that this person eventually drives the roadmap on their own.
• Push cross-cutting initiatives nobody else will — observability gaps, data model debt, perf regressions, API hygiene. The work that quietly compounds.
• Provide substantive code review, mentor where it lands naturally, and raise the level of design discussions when the design needs it, not just the implementation.
• Bring thoughtfulness and genuine passion for the work. Contribute to roadmap decisions with an eye on outcomes.

Senior Backend Engineer

• Captivation Software is looking for a strong full-stack software developer with functional UI experience but primarily focused on backend web services and servers.
• Experience with open-source integrations would be great and any experience with open-source tools is required - i.e. AWS, Docker, Kubernetes, EKS, Rancher, Tomcat, Spring, JMS and AWS.
• Strong communication skills are needed.
