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.\nThis 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.\nWhat you'll be doing:\n- Design, develop, and maintain integrations with data partners and customer systems ensuring reliable data flow and solid API performance.\n- Build and optimize RESTful APIs for both internal and external consumers.\n- Ship full-stack features with clean, well-tested, well-documented code, working independently on well-scoped work.\n- Troubleshoot production issues and improve performance alongside our DevOps team.\n- Refactor and modernize legacy code to improve maintainability.\n- Automate manual, repetitive processes to cut operational overhead.\n- Write the validation and verification tests that keep our integrations trustworthy.\n- Review teammates' code and give constructive, kind feedback.\n- All other duties as assigned.\nHow we work (and where you'll grow):\nWe 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.\n- 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.\n- 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.\n- Working in a large, real-world (brownfield) codebase with these tools is a plus if you're strong on the fundamentals.\nWhat you bring:\n- 4+ years of software engineering experience, as a full-stack developer or similar.\n- Solid C# and working proficiency in (or eagerness to ramp on) Go.\n- Front-end fundamentals: HTML, CSS, JavaScript and hands-on experience with a modern framework (Vue or React; we use Vue).\n- PostgreSQL and relational database design.\n- Building and consuming RESTful APIs.\n- A cloud-first mindset; comfort building and running apps in a cloud environment.\n- Strong fundamentals in version control (Git), testing, and documentation.\n- Curiosity about AI-assisted development and a track record of picking up new tools fast.\n- Clear communication, strong ownership, and the drive to take work all the way to done.\n- CS degree or equivalent practical experience.\nSONAR is an equal opportunity employer.\nBenefits:\n401(k)\n401(k) matching\nDental insurance\nDependent health insurance coverage\nDisability insurance\nFlexible spending account\nHealth insurance\nHealth savings account\nLife insurance\nPaid holidays\nParental leave\nUnlimited paid time off\nVision insurance\nWork from home\nWork Location: Hybrid remote in Chattanooga, TN 37402","company":"Sonar","rawCompany":"sonar","city":"Chattanooga","state":"TN","isRemote":false,"isActive":false,"createdAt":"2026-08-04T18:53:07.892Z","occupations":[{"code":"15-1252.00","title":"Software Developers","slug":"software-developers"},{"code":"15-1299.08","title":"Computer Systems Engineers/Architects","slug":"computer-systems-engineers-architects"},{"code":"15-1254.00","title":"Web Developers","slug":"web-developers"}],"industries":[{"code":"541511","title":"Custom Computer Programming Services","slug":"custom-computer-programming-services"},{"code":"541512","title":"Computer Systems Design Services","slug":"computer-systems-design-services"},{"code":"513210","title":"Software Publishers","slug":"software-publishers"}],"jobPosting":{"@context":"https://schema.org","@type":"JobPosting","title":"Full Stack Software Engineer","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.
