Platform Engineer

Responsibilities

• You'll work across a couple tightly coupled areas. We're flexible on entry points and will match scope to strengths.
• What you bring:
• At least 3 years of experience in platform, infrastructure, or backend engineering, preferably at a high-growth or AI-native company.
• Strong fundamentals in service-oriented architectures, networking, and systems design. You can reason about how data and traffic flow through a distributed system and what breaks first.
• Proficient in TypeScript, with hands-on experience operating production services on Kubernetes.
• Proven ability to take ambiguous goals from prototype to production, using customer feedback and operational data to drive product and architectural decisions.
• Strong code and data modeling skills - clean, scalable, and easy for the next person to extend.
• Take a product-focused approach to platform work. You measure success by whether the engineers you serve actually love and adopt what you built.
• Use AI aggressively in your personal engineering workflow. We're all heavy users of Claude Code, and regularly add new AI tooling across our organization.
• Bonus:
• Experience with MCP, OAuth, API gateways, or multi-tenant integration platforms.
• Experience with modern observability (OTEL, distributed tracing) and SRE best practices.
• Experience building internal admin or developer tooling consumed by both humans and agents.
• Experience working on agent or LLM systems - context management, tool use, sandboxing.

Requirements

• Identify as a builder.
• Are excited to work in-person from our new and spacious office in New York.
• Love working in a startup environment (experience in a startup or obsession with going zero-to-one).
• Enjoy working with people who are ambitious, caring, and think in systems.
• Thrive in a fast-paced iterative environment where experimentation is essential.
• What we bring:
• Pay & ownership - Competiti

Benefits

Additional Information

We're looking for a Platform Engineer to own the foundational primitives and surfaces that power Antimetal's product engineering velocity, service infrastructure, and the connectivity layer between our agents and customer environments. This role is core to how we ship. You'll architect and operate the systems that every agent invocation, every customer onboarding, and every code review depends on - our internal admin tooling, our deploy and observability pipelines, our MCP gateway, and the integration substrate that determines whether a new customer gets value in days versus weeks. You'll partner closely with product, FDE, and research, and your work will compound across every team that builds on top of you. About Antimetal Antimetal is building the future of infrastructure management . We're starting by creating a platform that investigates, resolves, and prevents issues-giving engineers their time back to focus on what they do best: building great products.
