> Remotebase · Brazil (Remote) · — · Posted 2026-06-16

**Workplace:** remote

**Department:** Engineering Department

## Description

We’re looking for a passionate Backend Developer to join our growing engineering team. You'll be working on scalable backend systems, collaborating with cross-functional teams, and shipping real products used by thousands of users.

**Key Responsibilities:**

-   Build and maintain the core engine: pricing / market-making, order books and matching,execution, and inventory-risk controls.
-   Research, prototype, and productionize quantitative logic for pricing, order-flow signals,and risk management.
-   Develop simulation and backtesting frameworks; run parameter sweeps and evaluateperformance against historical and synthetic order flow.
-   Implement the real-time delivery path (WebSocket fan-out) and authoritative data-feedingestion, with strict stale-data safety.
-   Contribute to the money-grade double-entry ledger and the settlement flows that dependon it.
-   Define and monitor key risk and performance metrics, and instrument the system so theyare observable in real time.
-   Write correctness-critical, deterministic, well-tested code — with attention to numericalprecision and edge cases — and keep a reference test suite green in CI.
-   Collaborate across engineering, product, and infrastructure to take work from spec toproductioninistic, test-covered code.

## Requirements

-   Strong backend engineering and computer-science fundamentals: data structures,algorithms, concurrency, and performance/latency awareness.
-   Proficiency in Python / TypeScript / Node.js — or strong adjacent experience and theappetite to be fully productive in TypeScript
-   A solid quantitative foundation: probability, statistics, and numerical methods.
-   Experience with relational databases (PostgreSQL) and event-driven or streamingarchitectures.
-   A habit of proving correctness with tests, and a fail-safe mindset — when something iswrong or unverified, stop rather than continue wrongly.
-   Clear communication with both technical and non-technical stakeholders.
-   Experience in trading, market-making, exchanges, derivatives/options pricing, or predictionmarkets.
-   Knowledge of market micro-structure, order-book dynamics, execution, and adverseselection.
-   Low-latency / real-time systems, WebSockets at scale, and event sourcing / CQRS.
-   Double-entry ledger or payments-platform experience.
-   Cloud at production scale (AWS EKS / RDS), Terraform, and observability (Datadog /Sentry).
-   Simulation / backtesting experience and statistical rigour about what a result does and doesn't mean.

## Benefits

-   In addition to a market competitive compensation, we have a reward philosophy that expand beyond this.

-   Fully remote
-   Opportunity to work with a truly global team
-   Flexible timings. You decide your work schedule
