Senior Full Stack Software Engineer: ERP, MES & Intranet Platforms

Company Overview

Amperesand is reinventing how the world powers its most critical systems.

We are facing a once-in-a-generation opportunity for infrastructure disruption. Electricity demand is skyrocketing, driven by AI factories, electric vehicles, and modern industrial growth. Energy supply is shifting to incorporate a more diverse mix of resources – including solar, gas, and batteries – at a massive scale.

And yet the power infrastructure behind our latest mega-projects hasn’t meaningfully changed in nearly 100 years. Supply chains for today’s infrastructure equipment can’t match the pace and sophistication of critical energy projects. Amperesand is building hardware and software that rewrites this broken power infrastructure playbook to support a new era of energy abundance.

We’ve built a new class of intelligent, software-defined power infrastructure products leveraging a decade of advanced medium voltage Solid State Transformer research that’s now ready for commercial deployment.

Our products and solutions go far beyond the capabilities of traditional electrical equipment. We make power systems that are faster to deploy, dramatically smaller and more efficient, and capable of supporting modern, dynamic energy needs for tomorrow’s most demanding energy consumers.

Scalable in-house advanced manufacturing capability is our foundation for meeting timeline and quality expectation to serve infrastructure customers around the world.

Amperesand is led by breakthrough energy hardware development veterans and funded by top tier investors who share our vision of building a category-defining energy technology company.

With hubs in San Francisco, Reno, and Singapore, our global team is laser focused on building foundational technology to solve the most pressing problems in power infrastructure at scale.

Join us in building the power foundation of the future!

Role Summary

This role is an opportunity to work with a high-agency startup team operating in the hard-tech and energy systems space. You will play a critical role in designing, building, and shipping the full stack of Amperesand’s ERP platform, company intranet, and the internal tools that our manufacturing, supply chain, finance, and corporate teams rely on every day.

This is a hands-on role that spans the entire stack. You will design data models and backend services, then build the React and TypeScript interfaces that sit on top of them — owning features end to end from requirements through production. The work covers ERP domains such as inventory, procurement, work orders, and reporting, alongside intranet capabilities such as employee directories, document and knowledge management, internal workflows, approvals, and self-service tools. You will also help introduce AI-assisted capabilities into these products, such as natural-language search over internal knowledge, document summarization, and workflow assistance.

The role requires close collaboration with product, design, backend, and domain expert teams — along with a strong sense of ownership, product judgment, and pragmatism in building reliable software for real-world operations. Beyond building new capabilities, you will also own and support our existing software products in production — keeping them healthy, responsive, and continuously improving for the internal stakeholders and customers who depend on them daily. This is a fast-paced environment with a small team and a large surface area, so we are looking for a go-getter who takes initiative, moves with urgency, and is willing to put in the hard work to see things through. AI is a first-class part of this roadmap rather than a side project: you will design and ship AI-powered capabilities integrated directly into the products themselves, and help set the standard for how we build them responsibly on top of sensitive internal company data.

This role is open at either the Senior or Staff level. Senior engineers are expected to own significant features and systems end to end and lift the engineers around them. Staff engineers are expected to do that while also setting technical direction across the ERP, MES, and intranet platforms, leading initiatives that span multiple teams, and taking responsibility for the long-term health of the architecture. We will calibrate the level to your experience during the interview process.

Responsibilities

Own the design, architecture, and delivery of full stack features across Amperesand’s ERP platform, intranet, and internal operational tools.

Build and scale backend services in Go that support mission-critical manufacturing, supply chain, and enterprise business workflows.

Build responsive, accessible, and performant web interfaces in React and TypeScript that make complex operational data understandable and actionable.

Design robust APIs, service interfaces, and data models that serve web applications, analytics systems, internal tools, and third-party enterprise integrations.

Deliver ERP capabilities spanning inventory management, procurement, supply chain operations, work order execution, production tracking, and enterprise reporting.

Build intranet features such as employee directories, document and knowledge management, internal announcements, approval and request workflows, onboarding flows, and self-service portals.

Integrate the intranet and ERP with internal systems such as identity and SSO providers, HR systems, document storage, and collaboration tools.

Design, build, and ship AI-powered features directly into our ERP and intranet products — natural-language search and Q&A over company knowledge, document understanding and data extraction, summarization, exception and anomaly flagging, and assistant-style workflows that remove manual operational work.

Build the backend foundations behind those features: retrieval and embedding pipelines, vector and hybrid search, context assembly from ERP and intranet data, prompt orchestration, and tool/function calling into existing services.
