# Senior Software Engineer (Latin America)

Confident powers analytical testing labs — the labs that test samples on behalf of businesses and report product safety to consumers and regulators at high volume. When a lab publishes a result through our platform, businesses make decisions with it and regulators rely on it. Our technology is essential to thousands of businesses across North America, and we're scaling our product to match a growing opportunity.

We're hiring an experienced engineer to help us build it. This is a senior individual-contributor role with real ownership: you'll ship features end-to-end, shape architecture, and raise the bar for how we build.

This role is fully remote and open to candidates anywhere, as long as you can maintain at least a 4-hour overlap with U.S. Pacific Time for synchronous work.

### Our Culture

---

We're a small and mighty U.S.-based team of exceptional individuals working remotely from around the U.S. and South America. Our number one priority is building products our customers love — so we don't care where you live, whether that's the urban maze of New York or the natural expanse of Costa Rica.

Our ethos, "aligned and empowered," shapes everything we do: how we make decisions, how we support one another, and how we hold annual retreats that reinforce our bonds and mission.

### What You’ll Do

---

- Design, build, and troubleshoot features across our stack: React/TypeScript, Python, PostgreSQL (via SQLAlchemy), and AWS.

- Own software development projects end-to-end, from ideation through execution, validation, and iteration.

- Collaborate with our Leadership, Engineering, Product, and Service teams on a weekly basis.

- Raise the engineering bar through thoughtful code review, mentorship, and leading by example.

### About You

---

- You’re a product-minded software engineer. You can take a project from zero to one, and you care as much about whether it solves the customer's problem as whether the code is clean.

- You thrive in ambiguity. Startups shift fast. You adapt as priorities change and know how to balance shipping customer value quickly with maintaining long-term stability.

- You’re curious and a fast learner. You naturally seek to understand the ‘why’ behind things. You enjoy figuring things out on your own and learning new skills to power up your productivity.

- You have a track record of ownership. You've shipped products people use, owned outcomes rather than tickets, and left every codebase you've touched better than you found it.

- You're an excellent communicator. You write clearly and precisely — especially with non-technical stakeholders — and you're comfortable with the demands of remote-first, written-first collaboration.

- You're humble and you care about others. You internalize feedback from anyone on the team, and you give direct, constructive feedback to help others improve. You believe honesty is kindness — and kindness is kindness, too.

Your Skills:

- 5+ years of professional software engineering experience building products people rely on in production

- Proficiency in modern JavaScript frameworks (React/TypeScript preferred)

- Proficiency in server-side web technologies (Python/Flask preferred)

- Proficiency with AI-development tools and best practices (Anthropic Claude Code or OpenAI Codex preferred)

- Bonus: experience designing/developing API for third party integrations

- Bonus: experience with Laboratory Information Management Systems (LIMS) or other regulated, data-heavy software — you'll ramp faster on our domain

### Benefits

---

- Cash Compensation: Competitive annual salary of $80,000-$110,000 USD, depending on experience and location.

- Equity Compensation: Employee-friendly stock grants with fair terms and future liquidity opportunities.

- Generous Time Off: 18 company holidays, up to 20 PTO days, and 8 sick days annually.

- Home Office Equipment: Generous budget to set up a productive workspace.

- Professional Development: Stipends for training, workshops, and conferences.
