• Proven track record of owning complex features or systems end to end: design, build, launch, iterate.
• Comfort operating in ambiguous environments: you can clarify requirements, propose approaches, and make decisions without needing rigid specifications.
• High ownership mindset: you think in terms of product and business impact, not just tasks completed.
• Strong communication skills: you document decisions, keep stakeholders updated, and communicate risks early.
• Experience designing APIs and backend architectures that serve multiple clients or products.

• Solid understanding of engineering fundamentals: data modeling, caching, performance, observability, testing.

   

AI and agents

• Real interest in AI and agents, with enough experience to integrate large language models or related services into products, for example calling an LLM API, designing prompts, or wiring tools.

• Experience with modern DevOps practices such as continuous integration and deployment, cloud infrastructure, and monitoring, sufficient to collaborate effectively with infrastructure-focused teammates.

• Prior work in early-stage companies or studios where you helped define engineering culture and practices.

   

Who You Are

• You are a builder who prefers shipping real things to only discussing them.
• You are energized by ambiguity and open problem spaces, not frustrated by them.
• You care about both the architecture and the user: you think about how your decisions affect the product and the business.
• You are comfortable being accountable: you make decisions, document them, and own the outcomes.
• You prefer lightweight process and clear ownership over heavy process and bureaucracy.

• You are not looking for a pure research role or a pure management role; you want to stay close to the code and the product.

   

How We Work

• Flat structure with direct communication between you, the founder, and the rest of the team.
• Multiple products in parallel, giving you exposure to a variety of problems and domains.
• Documentation and ownership: decisions get written down, and engineers are trusted to act on them.

• Remote-first: we work fully remotely and optimize for written communication and clear expectations.

   

Compensation

We offer a competitive salary and meaningful equity for the right person. Exact details will be discussed directly with candidates and calibrated based on experience and impact.

Description

You will be joining the project, an enterprise-grade software solution designed to help energy organization calculate, monitor, and reduce their CO2 footprint. The project is entering a critical phase of enhancement, moving beyond simple tracking to provide robust, data-driven calculation tools for sustainable materials and operational efficiency.

The project involves two main applications:

1. The first application is designed to visualize and analyze the estimated environmental footprint of a project during the tender stage. This application helps our client respond to proposals by providing an environmental footprint estimation for various pieces of equipment they sell. It currently has blueprints for about 11 items. The application generates reports that are included in the tender response to clients.
2. The second application performs an environmental impact assessment and generates reports for the actual construction phase of a project. It collects carbon and environmental impact data across five categories: site usage (water, electricity, materials), people traveling to and from the site, machinery used on site, and shipping for materials going back and forth from the site.

The project’s tech stack consists of a React-based static website with Ant Design for styling on the front end, and an API built on Strapi.js (an open-source Node.js headless CMS) with a MySQL backend. The application is hosted on Azure.

We are an outsourcing company looking for a Full-Stack JavaScript Developer to join our client — a product company providing hosting and co-location services. The client is actively developing their own infrastructure control panel / client portal used for provisioning services, managing servers and billing.

The product is already in production and used daily by internal teams and customers. At the moment, the main focus is on stability, edge cases and overall product quality rather than adding new features.

The product is a SaaS admin panel for hosting and infrastructure services. The backend integrates with VMware vSphere API through an internal abstraction layer, so experience with infrastructure or virtualization concepts will be a strong advantage.

The tech stack includes Svelte on the frontend and Node.js (Express) with JavaScript on the backend. Swagger / OpenAPI is used for API documentation. The team works in Slack (English), ClickUp, with weekly planning. There are testing, staging and production environments (moving to feature-branch workflow).

In this role you will own features end-to-end (frontend and backend), fix bugs, regressions and edge cases, maintain and extend the existing API (100+ endpoints), and work with Svelte UI flows focused on functionality rather than design. There is no designer and no Figma-based workflow — UI decisions are based on the existing product. You will do basic developer-level testing and work closely with system administrators who validate changes on real servers.

We are looking for a developer with strong Node.js / Express / REST API experience, comfortable working in an infrastructure-oriented product. Swagger / OpenAPI experience is a plus.
