Senior Builder (Sr Software Development Engineer) | Xome

As a Builder, you are core to the development at Xome. You are comfortable navigating multiple layers, environments, and methodologies of software development, and working across teams, technologies, and business products. The role designs, develops, deploys, and operates modern cloud-native applications across the full technology stack - user interfaces, APIs, data platforms, cloud infrastructure, CI/CD pipelines, and production support. A successful Builder at any level will be able to leverage AI-native development practices and tools such as GitHub Copilot and Claude Code to accelerate delivery, applying strong technical fundamentals, sound architectural thinking, and the judgment to solve complex problems with the right approach - whether that is code, automation, cloud platforms, data, or AI. Builders are engaged to work in agile development teams, product development pods, operational reliability research and incident resolution SWAT teams, and can also work autonomously outside of a virtual team. Builders are the "get it done" roles with the skillset, experience, mindset, know-how, and intuition to actively dig-in, collaboratively engage, curiously discover, maturely solution, expertly develop, and deliver. Builders are given the problems to solve that other engineers simply do not have the skills or breadth of experience to adequately deal with, and maintain quality and speed in their work. About the r ole Strategy Owns the technical vision, design, and delivery of one or more business capabilities or technology domains. Drives engineering decisions that balance business needs, scalability, security, reliability, and maintainability. Develops, prototypes, and evaluates solution approaches for a capability or domain, weighing tradeoffs and recommending a direction; identifies opportunities to improve systems, processes, automation, resiliency, and developer productivity; brainstorms and prototypes innovative approaches within their area. Owns how a capability is operated as well as how it is built: authors wiki, teaching, and reference material; envisions, builds, and rolls out appropriate observability; and improves surrounding business processes. Tracks the impact of these improvements in concrete terms, such as dollars saved and hours reduced. ​Technology & Engineering Design, build, test, deploy, and support web applications, APIs, integrations, and distributed systems. Strong hands-on development across the stack; builds and supports full-stack applications spanning UI, APIs, backend, data platforms, and cloud infrastructure; builds cloud-native solutions in Azure and/or AWS using containers and IaC; works with relational and NoSQL databases (schema design, performance optimization, indexing, data integration). Designs and implements RESTful APIs, GraphQL APIs, event-driven architectures, service-to-service integrations, and MCP-based solutions. Delivery & Operations Translates business requirements into technical designs, specifications, and implementation plans. Leads or contributes to the full SDLC (requirements through deployment and support); owns services throughout their lifecycle, including development, deployment, monitoring, maintenance, and continuous improvement. Uses observability tooling (logging, metrics, tracing, telemetry, dashboards, alerts) to proactively identify and resolve issues. Participates in incident response and RCA, producing RCA documents and preventative measures (including new telemetry, monitoring, and alerting); participates in an on-call rotation when required. Supports production deployments, releases, and operational activities. Maintains the parts of the development wiki, runbooks, and reference material relevant to owned services. Contributes to project planning, estimation, and successful delivery against schedules and commitments; delivers with high efficiency and velocity, consistently producing quality deliverables at speed. Collaboration & Leadership Collaborates with the same cross-functional partners to ideate, prototype, and deliver solutions. Conducts peer reviews and provides constructive technical feedback. Mentors junior engineers and contributes to the growth of the engineering organization. Facilitates technical discussions, design reviews, code walkthroughs, and knowledge-sharing sessions. Partners with business stakeholders to communicate technical capabilities, limitations, risks, and implementation approaches. May provide technical leadership for contractors or project teams. Applies secure engineering practices including authentication, authorization, encryption, secrets management, and vulnerability remediation. Utilizes AI-assisted tools to accelerate delivery while maintaining quality, security, and maintainability; applies engineering judgment to validate AI-generated code, designs, documentation, and procedures through testing, peer review, and observability. Establishes and maintains automated testing, continuous integration, continuous delivery, and DevSecOps practices. Champions clean, maintainable, well-crafted code and sets a high quality bar within their area. Produces and maintains technical documentation, architecture diagrams, support runbooks, and operational procedures. Continuously evaluates and adopts technologies, frameworks, and tools that improve engineering effectiveness. About y ou Minimum Qualifications Experience: 5–8 years of professional experience in a production environment, with demonstrated delivery of business-critical applications from design through production support. Stack proficiency: Strong full-stack engineering with .NET/C#, Python, JavaScript/TypeScript, React, and SQL; experience designing multi-tier, distributed, or cloud-native applications; experience with APIs, integrations, databases, and modern delivery tools. Preferred Qualifications Experience designing and operating multi-tier, distributed, or cloud-native platforms at scale, including IaC and containerized workloads (Azure and/or AWS) Demonstrated experience setting technical direction and driving adoption of AI-assisted development across a team or organization Experience setting standards for building and operating GenAI systems (retrieval quality, evaluation, observability, cost/latency, responsible-AI guardrails), with sound build-vs-buy judgment and when RAG or prompting is preferable to fine-tuning Track record of mentoring senior engineers and influencing engineering practices beyond a single team Experience with static analysis and security scanning tools (SonarQube, GitHub Advanced Security) Hands-on experience with MongoDB, including database and schema design, performance optimization, and indexing Experience building and operating observability solutions - dashboards, telemetry, and alerting - with Grafana, Application Insights, Log Analytics, or Datadog, and OpenTelemetry. AI / LLM engineering: Experience using AI-assisted tools as part of the SDLC; proven experience shipping production LLM/GenAI features (RAG pipelines, embeddings/vector search, prompt engineering, tool-calling or agentic workflows); experience defining evaluations, monitoring, and guardrails for AI features (quality, safety, cost, latency). Testing knowledge: Basic knowledge of Postman, Newman, or Playwright for API and end-to-end test automation; basic knowledge of performance testing tools and practices. Leadership & influence: Demonstrated experience mentoring junior engineers and providing technical leadership for contractors or small project teams.
