Preferred Qualifications Frontend depth and platform experience * Experience with server-side rendering and modern React frameworks (Next.js, Remix) or comparable meta-frameworks. * Experience building or contributing to a shared component library or design system at scale. * Experience with real-time UIs - streaming responses, WebSockets/SSE, optimistic updates, partial rendering. * Performance engineering experience - Core Web Vitals, bundle optimization, profiling, rendering performance. AI-assisted development * Hands-on experience using agentic coding tools (Cursor, Claude Code, GitHub Copilot, or equivalent) as a regular part of your workflow - beyond inline autocomplete. * Experience authoring durable project context for AI tools - AGENTS.md, CLAUDE.md, Cursor rules, custom skills, or comparable artifacts that encode team conventions. * Familiarity with plan-first / spec-first workflows when working with coding agents (plan mode, milestones, review gates) and with structured review of AI-generated code (hallucinated APIs, plausible-but-wrong logic, security regressions, prompt-injection risk in agentic flows). AI application exposure (growth-area; not required) * Experience integrating LLM APIs (OpenAI, Anthropic, Amazon Bedrock, Azure OpenAI, or equivalent) into web applications, even at the level of one or two shipped or seriously prototyped features. * Experience building user-facing surfaces for LLM features - streaming UIs, tool-use / function-calling interactions, structured output rendering, citation and grounding UX, regeneration and interruption flows. * Familiarity with the TypeScript AI ecosystem (Vercel AI SDK, Mastra, LangChain.js, official OpenAI/Anthropic TS SDKs, MCP clients) or working knowledge of the Python AI ecosystem (LangChain, LlamaIndex, evaluation frameworks). * Awareness of LLM-application concerns in production: evaluation strategies (golden datasets, regression checks, LLM-as-judge with appropriate skepticism), observability and tracing (Langfuse, LangSmith, Helicone, OTel-based), token accounting, latency budgets, caching, and content safety. * Awareness of AI-specific risks in user-facing surfaces - prompt injection via user input or retrieved content, output validation, PII handling, and responsible-use considerations. Domain & ways of working * Experience building internal tools, developer platforms, or operations applications at scale. * Experience working in a large, cross-functional engineering organization - coordinating across teams, navigating shared platforms, and contributing to org-wide standards. * Experience in media, entertainment, sports, or streaming technology is a plus but not required. Required Education * Bachelor's degree in computer science or a related technical field. ## Description Join our Business Operations engineering team as a Senior Software Engineer and become a core driver of organizational efficiency. You will play a key role in the development, maintenance, and enhancement of our critical application portfolio. In this role, you will leverage your deep technical expertise to deliver immediate impact, owning the end-to-end development of complex, medium-to-large-scale features and resolving high-priority system defects. You will act as a go-to technical authority, actively mentoring peers, defining and championing engineering best practices, and contributing to architectural decision-making. A growing portion of the team's roadmap involves surfaces that interface with large language models (LLMs) - assistive flows, summarization, search, and tool-use experiences embedded into our internal platforms. This role is an opportunity for a strong frontend engineer to grow into that work alongside more senior AI-application practitioners on the team. Responsibilities and Duties of the Role: Technical Leadership & Expertise * Own the design, development, and successful deployment of medium-to-large size software solutions, ensuring performance, quality, scalability, and security. * Drive software engineering best practices, including design, code quality, security and testability within the team. * Exhibit deep and broad technical expertise, with hands-on proficiency in key functional/specialty areas. * Serve as a primary technical resource for the team, offering guidance on technical issues and new feature development. * Participate in the design and delivery of features that integrate with LLM-backed services. For example streaming chat surfaces, structured-output forms, retrieval-grounded search, and tool-use interactions, partnering with senior AI-application engineers on the team. * Help establish and refine team practices for using AI coding tools (Cursor, Claude Code, or equivalent) effectively and responsibly in day-to-day development. Execution & Impact * Solve complex technical problems with an innovative and experimental can-do attitude grounded by advanced technical skill and technique. * Conduct thorough code reviews, focusing on requirements, design and coding standards, readability, testability, and optimization. * Mentor and guide the work of less experienced engineers to develop solutions. * Identify opportunities and recommend the development or implementation of solutions to improve products or processes with each iteration. * Document technical details for assigned features, fixes, and projects. Autonomy & Influence * Work independently with minimal guidance, applying judgment in selecting methods and techniques to resolve issues or satisfy requests. * Make timely, informed technical decisions that moderately influence the work of team members and related projects. * Participate in developing new technical approaches and tools. * Communicate complex technical information effectively to both technical and non-technical audiences. ## Related Videos - [WeAreDevelopers LIVE – AI, Freelancing, Keeping Up with Tech and More](https://www.wearedevelopers.com/videos/1786-wearedevelopers-live-ai-freelancing-keeping-up-with-tech-and-more) - [How Unit Testing Saved My Career](https://www.wearedevelopers.com/videos/1642-how-unit-testing-saved-my-career) - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [Test Driven Development with JavaScript](https://www.wearedevelopers.com/videos/222-test-driven-development-with-javascript) - [Engineering Mindset in the Age of AI - Gunnar Grosch, AWS](https://www.wearedevelopers.com/videos/1735-engineering-mindset-in-the-age-of-ai-gunnar-grosch-aws) - [From boy scouting to redrawing the landscape](https://www.wearedevelopers.com/videos/1140-from-boy-scouting-to-redrawing-the-landscape) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [What is Agentic Programming and Why Should Developers Care?](https://www.wearedevelopers.com/magazine/625-what-is-agentic-programming-and-why-should-developers-care)
