Re:Build Manufacturing

Role Description If you've worked alongside hardware teams, you know the damage that results from a missed change request or critical context that was never relayed to the right person. Reflow exists to close that gap. We're building the first AI-powered platform built for hardware product development, one that listens across the tools teams already use, maintains a structured picture of every program, and proactively coordinates across disciplines when things inevitably change. This is an early role for a hands-on AI engineer to design and build the agents at the core of our platform, backed by a parent company with deep roots in engineering and manufacturing. You'll own the AI systems that set our product apart: agents that understand hardware workflows, anticipate problems, and take action on behalf of engineering teams. What You'll Do - Designing, building, and iterating on LLM-powered agents that coordinate across engineering disciplines, surface project risks, and generate structured deliverables (proposals, SOWs, status reports) - Owning the agent orchestration layer (currently LangChain DeepAgent) and continuously evaluating whether to extend, replace, or supplement it as new frameworks and patterns emerge - Implementing robust tool-use patterns that connect agents to external systems (project management tools, CAD/PLM platforms, communication channels) via APIs and integrations - Designing and tuning prompts, chains, and retrieval strategies to maximize agent reliability, accuracy, and usefulness across diverse hardware project contexts - Building evaluation and observability infrastructure for agent performance, including tracing, cost tracking, latency monitoring, and automated quality benchmarks - Developing streaming agent interfaces that surface real-time progress, reasoning transparency, and proactive alerts to end users - Staying current with rapid advances in LLMs, agent frameworks, and related tooling, and translating that awareness into actionable recommendations for the team - Collaborating with frontend engineers on the UX of AI-powered features and with backend engineers on data pipelines and API design - Contributing to AI architecture decisions, code reviews, and engineering best practices Qualifications - 5+ years of production software engineering experience, with 2+ years focused on bringing LLM-based applications or agent systems to market - Demonstrated proficiency using AI coding tools (Cursor, Copilot, Claude, etc.) to accelerate development - Hands-on experience building and deploying agentic systems using frameworks such as LangChain/LangGraph, CrewAI, AutoGen, or custom orchestration - Strong understanding of LLM fundamentals: prompt engineering, function/tool calling, retrieval-augmented generation (RAG), context window management, and token economics - Proficiency with Python in production environments - Experience integrating LLM-powered features with external APIs, databases, and third-party tools - Experience designing and operating background job / async task pipelines (Celery, RQ, Temporal, or similar) for long-running agent runs and reliable retries - Experience building multi-agent systems with planning, delegation, and inter-agent communication patterns - Demonstrated ability to evaluate and adopt new AI tools and frameworks quickly, with a track record of staying ahead of a fast-moving field - Strong software engineering fundamentals: clean architecture, testing, version control, and code review practices - Ability to balance rapid experimentation with production-grade reliability Requirements - Direct experience with LangChain's DeepAgent or LangGraph for multi-step agent orchestration - Background in evaluation frameworks for LLM outputs (automated scoring, human-in-the-loop evaluation, regression testing for prompts) - Familiarity with vector databases and embedding pipelines (Pinecone, Weaviate, pgvector, or similar) - Experience with model serving infrastructure, fine-tuning workflows, or model selection/routing strategies - Understanding of authentication/authorization patterns (OIDC, JWT) and secure handling of user data in LLM contexts - Background in B2B SaaS platforms, project management tools, or technical collaboration products - Familiarity with hardware development, engineering workflows, or project management concepts (phases, gates, dependencies, requirements traceability) - TypeScript / React fluency, enough to pair with frontend engineers on streaming agent UIs and reasoning-transparency surfaces Benefits - Full health/dental/vision, bonus program, generous 401K, paid time off, annual learning stipend - Participation in Re:Build's LTIP equity program and opportunity for founder equity in potential spin-out Compensation & Location - Location: Remote-first, with preference for candidates in Boston, Seattle, Los Angeles, or other cities with Re:Build offices - Compensation: Base salary range of $143,000 to $215,000 with performance bonus and long-term incentive plan offered. Potential equity stake under independent spinout scenario.

About The Role This is a product-focused full-stack engineering role on a team building AI-driven power-user applications in the CAD/CAM space. You'll work across the entire stack—from crafting intuitive user experiences to building robust backend services—with a direct line of sight to how your work impacts real users. But this isn't your typical full-stack role. Our team regularly dives into technically deep work: platform engineering, MLOps, systems-level challenges, and performance-critical code. We're looking for engineers who aren't afraid to roll up their sleeves and tackle complex problems outside the usual web development comfort zone. The ideal candidate is a highly motivated self-starter who is passionate about software engineering, cares deeply about the user experience, and thrives when facing technically demanding problems. About The Team We're a team of nerds who genuinely love what we do. We're passionate about building great products and obsess over the details that make software feel right. We're also the kind of people who get excited about stepping outside our comfort zones. Whether it's picking up a new technology, diving into an unfamiliar domain, or tackling a gnarly technical challenge, we see those moments as opportunities to grow. If you're the type who lights up when facing a hard problem rather than shying away from it, you'll fit right in. At ReCAM, we are building new, automation-first, computer-aided manufacturing (CAM) applications. It’s early stage, which means we ship fast and adapt as we learn from user testing. At the same time, we strive for the kind of technical excellence that enables rapid development. If you enjoy building new and cool software, you’ll love it here! Export Control Requirement: Required Qualifications Bachelors in CS and 2 years in industry, or equivalent work experience Solid understanding of TypeScript and familiarity with at least one modern frontend framework such as React, Vue, Svelte, Angular Proficiency in writing backend APIs in strongly typed languages such as TypeScript, C#, Java, Go, or equivalent Strong CS fundamentals - understanding of networking and web technologies like REST APIs, gRPC, web-sockets, databases, HTML, CSS, etc. as well as a grasp on common OOP, functional programming and software architecture concepts Deep experience with at least one relational or non-relational database Familiarity with AWS or equivalent providers like Azure or GCP Understand proper usage of git and docker/containers Nice-To-Have's Bonus points for python3 chops, prior experience with data-engineering or Machine Learning Operations Bonus points for prior experience with tanstack query, router, start, etc. Some experience with C++ / cmake, CUDA, CAD, CAM, graphics APIs Prior start-up, early-stage or greenfield experience Personal projects/portfolio you would love to share and talk about Interview Process Recruiter connection Hiring manager screen Coderpad assessment Interview panel (4 rounds): 20–30 min: Product demo and alignment with product team 30 min: Live coding assessment, focused on practical work 15 min: Break 30 min: Technical Q&A panel 1 hour: System design panel Time for candidate questions You'll get a chance to meet the whole team you'd be working with daily.
