Our backers include Matt Schlicht (founder of Moltbook), the founders of Crunchbase and Republic, and VCs including Draper, Precursor, and Liquid2. We're working at the frontier of autonomous systems, building agents that don't just chat, but run entire businesses. Our system identifies business opportunities through market signals, validates ideas with live ad tests, builds and launches software products, and brings in human experts wherever agents fall short. That loop already runs end to end: from idea to launched product to first revenue. Over the next 12 months, our focus is on reliability, throughput, and self-improvement, making every launch better than the last. ## About the role We're looking for a hands-on AI Engineer to take ownership of the architecture and development of our autonomous agent system. You'll lead the technical direction of the platform, building multi-agent orchestration systems, self-improving agent harnesses, and AI-powered backend services. This is a highly technical leadership role that combines architectural decision-making with hands-on engineering. You'll be expected to ship production code, make key technical decisions, improve agent behavior in production, and help establish the engineering standards as the company scales. ## Responsibilities - Own the system architecture and make key technical decisions across the platform. - Design and build multi-agent systems and orchestration infrastructure that take products from idea to launch. - Develop self-improving agent harnesses, including feedback loops, evaluation systems, and memory. - Build and maintain AI-powered backend services on top of LLM APIs such as Anthropic, OpenAI, and Gemini. - Write production code, particularly around agent runtime and orchestration. - Debug and improve AI behavior in production through prompt engineering, structured outputs, retries, and fallbacks. - Break down complex technical challenges into actionable milestones and prioritize the engineering roadmap. - Establish engineering standards around code reviews, testing, observability, and release processes. - Lead and support the engineering team while remaining deeply involved in implementation. ## Requirements - 4+ years of professional software engineering experience. - Previous technical leadership experience at an early-stage company (Founding Engineer, Tech Lead, Head of Engineering, or similar). - Hands-on experience building and shipping multi-agent systems and orchestration frameworks to production. - Experience developing self-improving or self-evolving agent harnesses. - Strong backend engineering skills, including designing and maintaining APIs, services, and data flows. - Experience working with LLM-based systems, including prompt engineering, model configuration, structured outputs, embeddings, retrieval, and evaluation. - Daily hands-on experience with AI coding agents such as Claude Code, Cursor, OpenAI Codex, or similar tools. You should know how to delegate work to agents, review their output, and verify what they build. ## Nice to have - Strong TypeScript and Node.js experience. - Experience with Vercel AI SDK, Claude Agent SDK, or building custom agent runtimes. - Experience with PostgreSQL, Supabase, and pgvector. - Familiarity with background job systems such as Inngest or Pub/Sub. - Experience with Zod, Vitest, and GCP Cloud Run. - Experience growing or restructuring distributed engineering teams. - Interest in AI evaluation, safety, and observability. ## About Silver.dev ## Company Overview - **One-liner**: Silver.dev is a talent agency that connects venture-backed startups with vetted, interview-ready software engineers from Latin America. - **Entity Type**: Private (bootstrapped/founder-funded) - **Headquarters**: San Francisco, California, United States - **Founded**: 2023 - **Founders**: Gabriel (last name not publicly disclosed; founder & owner is a former Staff Engineer with hiring manager experience) ## Core Business - Primary industry: Staffing and Recruiting (specialized in software engineering talent). - Target customers: B2B; primarily venture-backed startups (half of clients are Y Combinator companies) and product-focused tech companies. - Mission/purpose: To help startups hire the right engineers without wasting weeks on interviews that go nowhere, by providing a no-BS, founder-led recruiting partner. ## Products & Services - **Direct Hiring**: Full-time, permanent placement of interview-ready engineers who are vetted by engineers and integrated directly into the client’s team. - **RPO (Recruitment Process Outsourcing)**: A flexible, dedicated hiring partner model that gives clients constant access to vetted candidates, designed for rapid scaling. - **Payroll & Employer of Record (EOR)**: Handles contracts, onboarding, and compliance for hiring across Latin America, allowing clients to focus on growth. - **Staffing**: Contract placement of talent under Silver.dev’s payroll, removing compliance overhead for the client. ## Market Standing - **Valuation/Market Cap**: Not disclosed. - **Key Metric**: 11 employees (up 62.5% year-over-year); 7,440 LinkedIn followers; 20,814 monthly website visits (up 35.2% year-over-year). - **Notable Investors/Partners**: None publicly listed (clients include Y Combinator and Initialized Capital portfolio companies). - **Growth Signals**: +62.5% headcount growth YoY; traffic growing +35.2% YoY; high client satisfaction (4.9/8 reviews on Clutch); average nine-day sprint from first call to signed offer for senior roles. ## Competitive Advantages - **Founder-led**: Run by a former Staff Engineer with hands-on hiring management experience, ensuring deep understanding of product-grade engineering needs. - **Engineer-vetted pipeline**: All candidates are screened by experienced engineers, not generic recruiters. - **Outcome-based pricing**: Clients pay only when a candidate signs, removing financial risk. - **Speed & quality**: Roles are filled in an average of nine days, with candidates who are truly interview-ready and culturally aligned with startups. - **LatAm focus**: Taps into a high-quality, cost-effective talent pool across Latin America, handling compliance and payroll. ## Strategic Focus - Continue to serve venture-backed startups, especially YC companies, by scaling the vetted talent pipeline. - Deepen services to include RPO and EOR, making it easier for US startups to hire compliantly across LatAm. - Expand the network of high-ownership, ambitious engineers prepared for startup environments. ## Why Work Here - **Culture**: Client reviews highlight a proactive, transparent, and collaborative team that “feels like an extension of the startup DNA.” High employee satisfaction with strong communication and adaptive problem-solving. - **Remote/Hybrid**: The company has offices in San Francisco and Buenos Aires, but job postings are predominantly remote.
