Location:

Remote (LATAM)

Job Overview:

Full-ownership senior software engineer responsible for building and evolving a new system in TypeScript that is replacing our existing one.

This is not a hand-off role — you take a problem from requirement to production and own it there. You'll work across both FE and BE stacks, make technical decisions, and be accountable for what you ship.

We expect you to use AI coding tools as a core part of how you work. Not occasionally — daily. Your velocity, code quality, and problem-solving should reflect effective AI tool use. What we care about is judgment: understanding what you ship, making the right decisions, and knowing when to push back on AI output.

This description applies across experience levels (L3–L4). Interview depth and expectations are calibrated to your level.

What You'll Own:

Features from requirements to production: you break them down, build them, ship them, monitor them

Technical decisions within your scope, with clear trade-off reasoning

Quality of your code and the areas you touch

Responding to incidents and dev-escalations in your domain

Building the new TypeScript/NextJS system that is replacing the legacy platform

What You'll Do:

Feature Development

Take feature requests, break them into tasks, estimate, and deliver independently

Build, maintain and support the new TypeScript/NextJS system designed to replace our existing platform

Write clean, tested, production-ready code that meets team standards

Make technical decisions for features and explain trade-offs clearly

Monitor your features in production — logs, metrics, alerts

Leave the codebase better than you found it (refactor, document, reduce debt)

Production Ownership & Incident Response

Respond to dev-escalations with urgency — investigate issues, communicate findings, contribute to resolution

Participate in incident response: at all levels, you are expected to show up, help investigate, and support resolution

L4+: Drive incident response for your domain — coordinate investigation, delegate tasks, communicate status to stakeholders, and ensure post-mortems happen

Write runbooks and keep documentation current as you build

Share on-call rotation after ramp-up period

Code Quality & Testing

Write unit and integration tests as part of feature work, not as an afterthought

Participate actively in code reviews — give thoughtful feedback, act on feedback you receive

Identify edge cases and risks during planning, not after deployment

AI-Augmented Development (Expected, Not Optional)

Use AI coding tools daily: code generation, debugging, test writing, exploring unfamiliar parts of the codebase, code review acceleration

Your output should be measurably faster because of AI tools

You understand everything you ship — AI is an accelerator, not a replacement for judgment

L3+: Help teammates develop effective AI workflows; contribute to team standards for AI tool use

L4+: Set team standards for AI tool usage — evaluate what delivers real value, ensure quality isn't sacrificed for speed

Collaboration

Work closely with Product, Design, QA, and other engineers

Contribute meaningfully to sprint planning and technical discussions

L3+: Mentor L1/L2 engineers through code reviews, pairing, and sharing knowledge

What You Bring To This Role:

Technical Environment

Primary stack: TypeScript/NextJS

Infrastructure: PostgreSQL, Prisma, AWS (EC2, RDS, CloudWatch, SQS, S3, NLB), Docker, GitHub Actions CI/CD, CodeRabbit

Testing: Vitest, Playwright

This role requires active, hands-on TypeScript/NextJS experience. Past professional experience with PHP will be a plus, but not required.

Expectations by Level:

L3: Leads small projects. Mentors L1/L2. Improves the codebase proactively. Teaches effective AI workflows.

L4: Technical authority for a domain. Drives cross-team projects. Sets team AI standards. Drives incident response.

Success Metrics:

Early on, you'll ship your first feature to production, understand the core architecture, and get your local development environment set up. From there, you'll be independently shipping features end-to-end and contributing to code reviews. As you grow further, you'll contribute meaningfully to technical discussions and handle dev-escalations in your area

On-Call:

Shared rotation (~1 week/month after ramp-up). Critical: 15 min. High: 1 hour.
