Role Description

Cultured Supply is hiring a junior software engineer to work closely with our lead engineer and help build Mission Control, our proprietary platform for turning market intelligence into actionable sales and operational workflows.

This is a generalist software engineering role with an emphasis on frontend development, product thinking, and user experience. You’ll build polished interfaces, connect them to real data and backend systems, and help shape how users interact with workflows involving market signals, opportunities, outreach, analytics, and CRM data.

Although the role leans toward frontend development, you’ll work across the Mission Control stack, including APIs, databases, integrations, AI-powered features, and internal tooling. You’ll follow features across the system and gradually take greater ownership, from understanding the problem through implementation, testing, and release.

This position is intended for someone who is approaching college graduation or graduated within the past two years. We’re looking for an early-career engineer who has built meaningful projects, cares about how software feels to use, and wants to grow quickly inside a small, ambitious team.

We don’t expect you to know every part of our stack from day one. We do expect curiosity, initiative, strong fundamentals, and a willingness to learn.

Employment: Full-time

Location: In person at our office in San Jerónimo, Monterrey. Being located in Monterrey, Mexico, is required.

Language: Spanish and highly proficient or fluent English.

If you’re still completing your degree, you must be available during working hours.

Responsibilities

- Ship features across the frontend, backend, and data layers of Mission Control.
- Build polished interfaces for market intelligence, opportunities, outreach, analytics, and customer workflows.
- Turn complex data and operational processes into experiences that feel clear, responsive, and intuitive.
- Translate product ideas and designs into working, production-ready software.
- Design and build integrations with APIs, CRMs, and other customer systems.
- Work closely with engineering and operations to turn real business processes into reliable software.




- Contribute to product and design decisions, not only implementation.
- Create reusable components and improve the consistency and quality of the product.
- Write clean, well-tested code and take ownership of the features you build.
- Use AI development tools productively while understanding, reviewing, and verifying what you ship.
- Participate in code review, technical planning, and the continuous improvement of our engineering practices.

What We Look For

- High agency: You can take a problem, investigate it, and move it forward without waiting for step-by-step instructions.
- A strong learning instinct and genuine curiosity about unfamiliar systems, tools, and domains.
- Good product judgment: you think about what the user needs, not only what the ticket says.
- Attention to visual details and the overall quality of the experience.
- Comfort operating in a startup environment where priorities evolve and problems may initially be ambiguous.
- A pragmatic, execution-oriented mindset: you can build a solid first version, learn from it, and iterate.
- The ability to explain your decisions, ask thoughtful questions, and accept direct feedback.
- Comfort using AI development tools.

Core Skills & Experience

- Currently approaching university graduation or graduated within the past two years.
- Strong software engineering fundamentals, including APIs, relational databases, and application architecture.
- Experience building frontend applications.
- Understanding of responsive design, component architecture, application state, forms, and data fetching.
- Ability to translate a product idea or design into a polished, usable interface.
- Comfort working across the stack and learning unfamiliar tools when a project requires it.
- Familiarity with Git, pull requests, code review, and collaborative repositories.




- Ability to troubleshoot independently and verify that a feature works beyond the happy path.
- Clear written communication and the habit of documenting important decisions.
- Evidence of your ability to build through internships, freelance work, university projects, or substantial independent projects.

You don’t need to check every box. If most of this resonates with you, we encourage you to apply.

You should be comfortable using tools such as Codex, Claude Code, Cursor, or similar coding agents. We don’t expect you to know every tool already, but we do expect curiosity, critical thinking, and a willingness to learn.

Nice to Have

- Experience creating dashboards, data visualizations, or other data-heavy interfaces.
- Familiarity with design tools such as Figma or Claude Design.
- A portfolio demonstrating strong frontend execution or product-design sensibility.
- Experience building AI-enabled product features.
- Experience shipping and maintaining a project used by real people.
