Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Full Stack Software Engineer - **Company:** Sonar, Inc. - **Location:** Chattanooga, TN, United States (Remote available) - **Experience:** Experienced - **Contract:** Permanent contract - **Skills:** HTML, JavaScript (Programming Language), Application Programming Interfaces (APIs), Artificial Intelligence, Application Performance Management, C Sharp (Programming Language), Cascading Style Sheets (CSS), Relational Databases, DevOps, Electronic Data Interchange (EDI), PostgreSQL, Software Engineering, SONAR (Symantec), Data Streaming, ReactJS, Git, Vue.js, Production Code, Front End Software Development, Restful APIs, Code Restructuring, Software Version Control - **Published:** July 4, 2026 - **Apply:** https://www.indeed.com/viewjob?jk=528c00273880c747 ## About the Role You'll use AI-assisted tools day to day and get sharper at them here. Experience with agentic coding tools is a strong plus; a genuine willingness to learn them well is a requirement. - You'll help turn rough, agent-generated prototypes into production-quality code and you'll learn our bar for readability, extensibility, and security by pairing with senior engineers who do this constantly. Early on you'll do this with guidance; over time you'll own more of it. - Working in a large, real-world (brownfield) codebase with these tools is a plus if you're strong on the fundamentals. What you bring: - 4+ years of software engineering experience, as a full-stack developer or similar. - Solid C# and working proficiency in (or eagerness to ramp on) Go. - Front-end fundamentals: HTML, CSS, JavaScript and hands-on experience with a modern framework (Vue or React; we use Vue). - PostgreSQL and relational database design. - Building and consuming RESTful APIs. - A cloud-first mindset; comfort building and running apps in a cloud environment. - Strong fundamentals in version control (Git), testing, and documentation. - Curiosity about AI-assisted development and a track record of picking up new tools fast. - Clear communication, strong ownership, and the drive to take work all the way to done. - CS degree or equivalent practical experience. ## Description SONAR is looking for a Full Stack Software Engineer to help build and optimize the integrations that connect our platform to data partners and customers. You'll own real integration work end-to-end. Designing APIs, wiring up reliable data exchange, and shipping full-stack features on a fast-moving team that leans heavily on modern AI-assisted development. This is a mid-level role: we expect you to build and ship features independently, and we'll pair you with senior engineers on the harder calls (security, architecture, taking rough prototypes to production). We work remote-friendly across the U.S.; we get together in the Chattanooga office periodically, so occasional travel is part of the job. What you'll be doing: - Design, develop, and maintain integrations with data partners and customer systems ensuring reliable data flow and solid API performance. - Build and optimize RESTful APIs for both internal and external consumers. - Ship full-stack features with clean, well-tested, well-documented code, working independently on well-scoped work. - Troubleshoot production issues and improve performance alongside our DevOps team. - Refactor and modernize legacy code to improve maintainability. - Automate manual, repetitive processes to cut operational overhead. - Write the validation and verification tests that keep our integrations trustworthy. - Review teammates' code and give constructive, kind feedback. - All other duties as assigned. How we work (and where you'll grow): We build with agentic and spec-driven development as a normal part of the workflow, and a lot of our roadmap starts as fast prototypes sometimes from Product or other teams, not just engineering. ## Related Videos - [The AI-Native Engineering Org: What’s Real, What’s Hype, What’s Next](https://www.wearedevelopers.com/videos/100004-the-ai-native-engineering-org-what-s-real-what-s-hype-what-s-next) - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Lessons learned from building a thriving Vue.js SaaS application](https://www.wearedevelopers.com/videos/1666-lessons-learned-from-building-a-thriving-vue-js-saas-application) - [The Resilience of the World Wide Web](https://www.wearedevelopers.com/videos/1281-the-resilience-of-the-world-wide-web) - [But, you're not Facebook](https://www.wearedevelopers.com/videos/378-but-you-re-not-facebook) - [Common Mistakes in Vue.js and How to Avoid Them](https://www.wearedevelopers.com/videos/958-common-mistakes-in-vue-js-and-how-to-avoid-them) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 131 - AI'm not sure about OSS](https://www.wearedevelopers.com/magazine/472-dev-digest-131-ai-m-not-sure-about-oss) - [Dev Digest 137 - AI'm not sure about this](https://www.wearedevelopers.com/magazine/485-dev-digest-137-ai-m-not-sure-about-this) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [What is Software Engineering in the Age of AI?](https://www.wearedevelopers.com/magazine/640-what-is-software-engineering-in-the-age-of-ai)
