Engineering Remote · Argentina Paid in USD Full-time

Semi-Senior Software Engineer

The people who decide where billions go run on software someone has to write well. You'd build the APIs, the agents and the integrations that turn scattered market data into a decision an investor can defend. Backend first, generalist when the work asks for it.

Backend features end to end, API to integration

Experience

3–5+ years backend, owning real features

Compensation

USD, discussed on call 1

Process

Node.js / TypeScript Python Cloud architecture & infrastructure (AWS, Azure or GCP) SST / Terraform AI frameworks: LangGraph, LangChain, CrewAI, SageMaker AI agents: AI SDK, Mastra, Hermes Agent, Google ADK LLM providers & gateways: OpenAI / Anthropic SDK, OpenRouter, Vercel AI Gateway Next.js / React SQL / NoSQL Nice: Snowflake, streaming infrastructure

Fit check

Tick what's true. We'll tell you straight.

Nothing is sent anywhere. This is for you, not us. Six statements, honest answer only.

Intelligence APIs, automated workflows, AI agents that read investment memos. Most of the time goes into working out what the right thing is before writing it. The code is what a good thought process leaves behind.

Integrations

Affinity, PitchBook, Harmonic and the rest. Real integrations that hold up, not duct tape with a retry on top.

With users

Calls with the people using what you built: analysts, ops leads, partners. You hear the complaint first-hand, not through a ticket.

Review

Reading other people's code and having yours read, and then checking that what shipped actually works for the person who asked for it. The diff is the smaller half.

Three things you ship in your first year

An intelligence API a fund opens every morning

Market data in, actionable signal out. Owned by you from the schema to the endpoint the client calls.

An AI agent that earns its place in the workflow

Reads memos and deal data, surfaces what a partner should look at twice. Useful, not a demo.

An integration nobody has to babysit

One of the third-party sources, rebuilt properly: reconciled, monitored and boring to operate.

• You take ownership of problems, not tickets.
• Ambiguity is where you start, not where you stop.
• You want the client relationship, not protection from it.

• You want a spec handed to you and a quarter to deliver it.
• You need permission before fixing something you can see is broken.
• Talking to the people who use your work sounds like a distraction.
• You need a large team's process around you to feel safe shipping.

Same for every role, every level.

Remote-first

Work from anywhere in Argentina. If you live near Buenos Aires or Córdoba, you're in the office two days a month.

Performance bonus

On top of your salary, tied to how you perform.

Salary in USD

Paid in dollars, every month, reviewed twice a year.

Objective-based, with real adaptability. A few hours of overlap with US clients is the only fixed part.

14 days PTO + holidays

Taken, not accrued and forgotten. Local holidays on top, and the week between Christmas and New Year's off.

Working equipment

A MacBook Pro to work on, provided by us.

Tech budget

The tools that make you faster: Cursor Pro, Claude Pro, ChatGPT, whatever you'll actually use.

Courses, training and conferences that matter to the work. Ask, don't petition.

Written levels and what each one expects. Lead and staff tracks exist and are open.

High trust

Autonomy in exchange for excellence. Nobody checks whether you were online at nine.

What you've built, what you want next. We name our clients here.

Real problem, together

A backend problem from actual work. No leetcode, no take-home over your weekend.

Founders + the team

Mutual diligence. Ask us the uncomfortable questions about money, clients and churn.

Then

Offer or a real reason, within a week of the last call.

We keep you updated at every stage of the process.
