Note: The job is a remote job and is open to candidates in USA. Underline is a connectivity infrastructure company that deploys multi-purpose fiber networks to support communities and provide ultra-fast internet access. The company is seeking a Senior Full-Stack Engineer to own software features end to end, from business needs and technical design through implementation, deployment, and monitoring, while contributing to AI-assisted development, system quality, and team growth.
Responsibilities
- Features, end to end. You take work from a loosely defined business need through design, implementation, deployment, and monitoring. Nobody hands you a spec. You write it and defend the tradeoffs in it. Sometimes the right answer is that the whole thing should be smaller, and we expect you to say so
- AI-assisted delivery . You use Claude Code as a core part of how you work: decomposing problems so agents make real progress, running parallel threads when that helps, and reading every diff before it lands. You also improve how the team does this, from the CLAUDE.md files and MCP servers to the gates that make agent output safe to trust
- The stack. Backend services in Go, event-driven integrations over NATS, GraphQL and REST APIs, and the Ember front-end that consumes them. You care what the screen looks like and how it feels to use
- The quality bar. Tests, CI/CD, observability, and performance are your responsibility, not a separate team’s. The more code agents generate, the more this matters
- The team. You make pragmatic calls under ambiguity, write down the patterns worth repeating, interview candidates, and make the engineers around you better with these tools
Skills
- This is a U.S. Based position, travel to quarterly off-site company retreats is required
- • 8+ years of professional software engineering experience, including production ownership across the stack
- • Current, demonstrated practice with agentic coding tools
- • Deep expertise in Go and strong command of PostgreSQL, including schema design and query optimization
- • GraphQL and REST APIs in production, plus TypeScript and a modern front-end framework (Ember, React, Vue) and a utility-first CSS framework like TailwindCSS
- • Docker and Kubernetes in production, and event-driven architectures on a message system such as NATS, Kafka or RabbitMQ
- • Test-driven development and CCI, plus a solid grasp of web security, authentication and authorization
- • Strong debugging across distributed systems including code you did not write
- • Experience in telecom, broadband, or infrastructure companies
- • Local to the Dallas, TX area
