Software Engineer II
Posted Updated
Summary
Software Engineer II at Helix, a genomics/health-tech company, based in Mexico City with hybrid or remote (80+ km outside CDMX) options. You spend much of the day directing AI coding agents that plan, write, and test code, contributing across the full development lifecycle on lab systems or AI-native internal tools using Go/Python/Java/TypeScript, APIs, databases, and AWS.
Who We Are & What We Do
At Helix, our mission is simple: to help everyone improve their lives through their DNA. Ready to make a real-world impact with your skills? At Helix, we're transforming healthcare by making genomics a standard of care. We partner with health systems and life science companies to accelerate the integration of genomic data into clinical practice. Join us in building a future where healthcare is personalized, proactive, and powered by genomics.
Your Career Path & Development
We are committed to your long-term growth. We invest in you through:
- AI-Native Engineering: Most of your day is spent directing agents that plan, write, and test code, so you can focus your judgment on architecture, review, and the calls only a human should make.
- Continuous Learning: Sharpen your skills with full access to the entire Udemy learning database.
- Internal Mentorship: Learn from experts across our global team through tech demos, pair programming, and collaborative projects.
- Clear Advancement: We provide a framework for you to grow from one role to the next, with clear expectations and support from your manager.
- Travel: Opportunities to travel to the US for collaboration with our global teams.
What is special about these roles?
At Helix, our engineering teams build the systems that make genomic medicine real — from the lab bench to the internal tools that power our operations. We’re hiring Software Engineers II across two teams. Depending on your background and interests, you may be matched to one of the following:
- Lab Systems (LABS) - Lab Systems (LABS) — Owns the laboratory-facing services that keeps Helix’s sequencing & supply chain operations running. You’ll build and maintain scalable platforms and fullstack software that support the lab and integrates with analysis pipelines: lab workflows, instrument automations, sample accessioning, inventory management and distribution.
- Enterprise Tools / AI Swarm - Builds AI-native internal tooling that gives every Helix team superpowers. You’ll own internal projects end-to-end: taking stakeholder requirements, deciding on the technical approach, and building working solutions using AI-assisted development, with senior engineer review before anything ships.
As a Software Engineer II, you will:
- Contribute to projects across the full development lifecycle - building features, fixing bugs, and helping ship reliable solutions that have real impact on users.
- Work with AI agents as a default part of how you ship. Scope tasks clearly enough for an agent to execute independently, review and correct its output with the same rigor you'd apply to a teammate's PR, and know when a task needs a human driving instead.
- Write well-tested, readable code, participate in code reviews, and engage with feedback as a way to grow.
- Collaborate with your team, product managers, and cross-functional stakeholders to understand requirements and build solutions that work in practice.
- Develop familiarity with Helix’s products, codebase, and cloud infrastructure, steadily taking on more independent ownership as you grow.
- Surface problems and questions proactively - you don’t wait to be told something is wrong.
About you:
- 3+ years of professional software engineering experience.
- Proficiency in at least one backend language (Go, Python, Java, or similar) — for Enterprise Tools roles, experience with TypeScript or scripting languages is also relevant.
- Comfortable connecting APIs and working with databases.
- Familiarity with cloud basics (AWS or similar) - you don’t need to be an expert, but you shouldn’t be starting from zero.
- Hands-on experience directing AI coding agents (e.g., Claude Code, Codex, Cursor, Copilot) as part of your regular workflow, including reviewing and correcting their output.
- Solid fundamentals: you write readable code, test your work, and ask good questions.
- Self-directed and proactive - you move work forward and surface blockers early.
- Adaptable and curious - willing to learn a new domain (lab operations, genomics, or internal tooling) and pick up unfamiliar technologies.
- Fluent in English, both written and spoken.
Pluses:
- Experience building internal tools or enterprise integrations (e.g., Google Workspace, Slack, or AWS APIs).
- Familiarity with laboratory information management systems (LIMS) or similar operational software.
- Familiarity with regulated software systems (e.g., HIPAA, ISO, FDA).
- Experience with AWS technologies and serverless infrastructure.
- Exposure to a startup or scale-up environment.
