Descrizione del lavoro

Engineering Remote · Argentina Paid in USD Full-time

Senior Software Engineer

Someone has to decide how the system is shaped before anyone can build in it. You'd own the architecture behind AI dealmaking: real-time signal processing, agent systems that reason about opportunities, and a platform that grows without the rewrite everyone saw coming.

The architecture, and the projects built on it

Experience

5–7+ years backend with system design ownership

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 Snowflake Next.js / React Nice: streaming infrastructure, data platforms at scale

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. Still hands on keyboard. Intelligence APIs, agent systems, the parts of the platform nobody else should have to touch first. Most of it is deciding what the right thing is. The code is what a good thought process leaves behind. Deciding how it should be shaped, writing the trade-off down, and being the one accountable when it is wrong.

Leading the project

Product, business, and the funds themselves. You align them on what a project is for, set the cadence, and own the expectations. You shape the roadmap in those rooms rather than receive it afterwards.

Multiplying

Review, pairing, mentoring. Review here means making sure what we ship actually works, not only that the diff reads well.

Three things you'd ship in your first year

01 A platform that survives its own success

Prototype to production without the rewrite. You pick the boundaries and live inside them.

02 An agent system that reasons, not just summarises

Memos, signals and deal data in; a judgement a partner will actually act on out.

03 A team that ships better than when it started

Standards, review culture and the architectural taste that outlasts any one feature.

• You'd rather shape the roadmap than be handed it.
• You think in trade-offs and can write down why you chose one.
• Your best work makes other engineers faster.
• You've run a project, not just the code in it. Scope, cadence, expectations.

Be honest, probably not for you if

• Senior means "stops coding" to you.
• You want the architecture decided before you arrive.
• Telling a stakeholder the date moved is someone else's job.
• Explaining a technical call to a business stakeholder feels beneath the job.
• You need a large team's process around you to feel safe shipping.

What you get

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.

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.

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

System design, together

An architecture problem from actual work, argued out loud. 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.

Who you'd be working with

We keep you updated at every stage of the process.
