Junior Software Test Engineer Jobs in Tennessee (NOW HIRING)

Job Summary:
RevSpring is seeking a Senior Software Engineer for their Search Services and Applications team. The role involves designing and building cloud-based search services with a focus on AI-powered search, while providing technical ownership and contributing to architectural decisions to ensure scalability and reliability.
Responsibilities:
• Design, implement, and review code for search services and applications; apply sound design patterns and continuously improve quality.
• Partner with peers on design and implementation details and provide actionable feedback through code and design reviews.
• Participate in and contribute to Agile DevOps team activities. Effective in paired programming and working independently.
• Help drive clarity in planning. Contribute to task definition, prioritization, and assignment. Drive deliverables with a sense of urgency and ownership along with surfacing risks, mitigating them, and suggesting course corrections when appropriate.
• Own multiple products with a DevOps and service-ownership mindset. Deliver quality solutions with TDD, test automation, instrumentation, monitoring, secure/defensive coding, resiliency, and scalability.
• Select methods and procedures on new or special assignments collaboratively.
• Design, develop, review, and deliver application and service architecture for search (indexing, query, relevance, and retrieval pipelines).
• Implement and optimize OpenSearch/Elasticsearch indices, analyzers, mappings, and query DSL to improve relevance, latency, and cost.
• Build and operate vector search capabilities (embeddings generation, indexing, kNN search) and hybrid retrieval (keyword + vector), including evaluation and tuning.
• Contribute to LLM-enabled search experiences (e.g., RAG, reranking, query rewriting, and answer grounding) with a focus on safety, latency, and measurable relevance.
• Collaborate on work with the team and contributing teams.
• Engage in cross-functional teams and ensure successful project and/or product delivery.
• Contribute improvements to shared resources and engineering practices (internal libraries, tooling, documentation, and operational runbooks) that help the team deliver reliably.
• Make sound technical decisions, drive alignment through clear options/trade-offs, and unblock delivery within the search domain.
Qualifications:
Required:
• Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience.
• 5+ years of software engineering experience.
• Design and deliver robust, scalable backend services in Java and/or Python on AWS, including search-heavy workloads.
• Hands-on experience integrating AI capabilities into products (e.g., embeddings, LLMs, NLP, reranking) and operating them in production.
• Experience with OpenSearch or Elasticsearch: index design (mappings/analyzers), ingestion, query DSL, and performance/relevance tuning.
• Ability to design relevance experiments and evaluate quality using offline metrics (e.g., NDCG/precision/recall) and online signals (A/B tests, click/engagement data).
• Experience with vector search and/or RAG systems: embedding pipelines, hybrid retrieval, prompt design/guardrails, and observability for latency and quality.
• Assess business value, trade-offs, risks, and technical constraints during discovery and planning.
• Help drive the technical direction for AI-driven search and backend services within the team, aligning designs with product goals.
• Lead or contribute to architectural reviews and clearly communicate recommendations and trade-offs.
• Evaluate and recommend new technologies to add to the stack.
• Stay current with industry trends and emerging technologies.
• Mentor junior software engineers across one or more functional areas.
• Help foster an inclusive environment where team members are motivated to succeed with autonomy, mastery, and purpose.
• Share technical expertise and knowledge on relevant topics.
• Contribute to the team’s technical direction by proposing improvements, sharing learnings, and raising the bar on engineering practices.
• Work effectively with product leaders, executives, and cross-functional teams to align on goals and architecture.
• Serve as a technical lead for a project(s) or component(s), coordinating with partners to deliver on time.
• Provide complete, actionable, and timely technical feedback.
• Articulate technical decisions with clear rationale in design meetings and discussions.
• Adapt communication of complex technical topics to different audiences.
