Senior Software Engineer

We&aposre building the future of marketing operations through AI employeesautonomous agents that think, adapt, and execute like your best marketing team members. After seeing incredible response from advertisers and agencies, we&aposre assembling our core team to deliver on this vision.

Think of us as the Formula 1 pit crew for digital marketing. Just as F1 teams orchestrate split-second decisions with precision timingadjusting strategy, swapping components, and optimizing performance in real-timeour AI employees coordinate seamlessly across platforms, campaigns, and creative assets to maximize marketing performance at machine speed.

You&aposll be our first Senior Backend Engineer, architecting and building the foundational systems that enable AI employees to operate at scale across millions of marketing campaigns. This isn&apost about building typical web applicationsyou&aposre creating the distributed infrastructure that coordinates autonomous agents managing billions in advertising spend.

What you&aposll build:

• AI Agent Orchestration Engine

  - Distributed system coordinating thousands of AI employees across multiple advertising platforms simultaneously

• Real-time Campaign Processing Pipeline

  - Sub-second data ingestion and decision-making systems handling millions of campaign events daily

• Multi-platform API Integration Layer

  - Robust, fault-tolerant connections to Facebook, Google, TikTok APIs with intelligent rate limiting and retry logic

• High-stakes Decision Framework

  - Mission-critical systems that execute budget changes, campaign optimizations, and creative swaps affecting real business outcomes

If you are interested, send an application to [HIDDEN TEXT]. Applications should include:

1. A brief note on your distributed systems and scaling experience
2. An example of a complex system you&aposve architected from scratch
3. Your thoughts on the unique challenges of building infrastructure for AI agents

Distributed Systems Architecture

• 5+ years building large-scale distributed systems that handle millions of concurrent operations
• Deep experience with microservices, event-driven architectures, and asynchronous processing
• Understanding of CAP theorem trade-offs and designing for eventual consistency

High-Performance Data Processing

• Experience with real-time data pipelines processing millions of events per minute
• Knowledge of stream processing frameworks (Kafka, Apache Storm, or similar)
• Expertise in optimizing database performance at scale (PostgreSQL, Redis, time-series databases)

API Integration & Reliability

• Extensive experience integrating with third-party APIs, especially rate-limited and unreliable services
• Building robust retry mechanisms, circuit breakers, and graceful degradation patterns
• Understanding of webhook processing, API versioning, and backward compatibility

Mission-Critical System Design

• Experience building systems where downtime directly impacts business revenue
• Knowledge of monitoring, alerting, and observability for complex distributed systems
• Understanding of security best practices for handling sensitive business data

AI/ML Systems Experience

• Experience building infrastructure for AI/ML workloads and model serving
• Understanding of how to scale LLM interactions and manage AI service dependencies
• Knowledge of prompt engineering, model orchestration, or agent frameworks (preferred)

Startup Scale Engineering

• Thrives in 0?1 environments where you build foundational architecture from scratch
• Can balance rapid iteration with long-term scalability considerations
• Experience scaling systems from thousands to millions of users

Founder-Level Ownership

• Takes full ownership of system reliability and performance outcomes
• Previous startup or early-stage engineering leadership experience preferred
• Comfortable making architecture decisions that affect company trajectory
  

You&aposll be architecting systems at the intersection of several challenging domains:

• Real-time advertising APIs

  with strict rate limits, complex authentication, and variable latency

• AI agent coordination

  managing thousands of autonomous decision-makers simultaneously

• Financial transaction processing

  where system errors directly impact customer ad spend

• Multi-tenant architecture

  supporting agencies managing hundreds of client accounts

The engineering challenge is building systems that are simultaneously fast, reliable, and intelligent while handling the complexity of modern advertising platforms.

Core Technologies:

• Languages:

  Python/Go/Rust for core services, with flexibility based on use case

• Infrastructure:

  Kubernetes, Docker, cloud-native architecture (AWS/GCP)

• Data:

  PostgreSQL for transactional data, Redis for caching, ClickHouse/TimescaleDB for analytics

• Messaging:

  Kafka or similar for event streaming and service coordination

• Monitoring:

  Prometheus, Grafana, comprehensive logging and distributed tracing

Architecture Principles:

• Event-driven microservices with clear service boundaries
• Immutable infrastructure and GitOps deployment practices
• Comprehensive testing including chaos engineering
• Security-first design with encryption at rest and in transit
  

We operate like an F1 teamevery decision matters, timing is critical, and excellence is non-negotiable. You&aposll be working with exceptional people who expect exceptional results.

Culture fit:

• Obsessed with system reliability and customer outcomes, not just code elegance
• Comfortable with ambiguity but decisive when architectural clarity is needed
• Collaborative but capable of independent problem-solving
• Deep technical expertise combined with business impact awareness

• Ground floor opportunity

  to architect systems for the future of marketing operations

• Direct customer impact

  - your code directly affects small business growth and success

• Complex technical challenges

  at the intersection of AI, advertising, and distributed systems

• Exceptional team

  of experienced operators and technologists

• Significant equity

  appropriate for a founding-level engineering leader
