About the Product

We are building a US-based, data-driven product with a strong focus on scalability, performance, and cost efficiency.

Our mission is to design a modern data platform that transforms raw behavioral and monetization data into reliable, actionable business insights — in near real-time.

For us, data engineering is not just about moving data.
It’s about:

• Designing resilient architecture
• Optimizing for performance and cost
• Building reliable automation
• Ensuring architectural integrity at scale
•  

Role Overview

We are looking for a Senior Data Engineer who will take ownership of the data platform architecture and drive technical excellence across ingestion, modeling, and performance optimization.

This role requires deep expertise in SQL, Python, AWS infrastructure, and modern data stack principles. You will not only build pipelines — you will define standards, lead architectural decisions, and proactively improve system efficiency.

You will play a critical role in ensuring that data flows seamlessly from event streams to business-ready datasets while maintaining high performance, reliability, and cost control.

What Makes This Role Senior-Level

As a Senior Data Engineer, you will:

• Own architectural decisions for the data platform
• Identify scalability bottlenecks before they become incidents
• Optimize data infrastructure for performance and cost
• Lead technical code reviews and set engineering standards
• Mentor mid-level engineers
• Act as a technical partner to Product and Analytics stakeholders
• Balance real-time and batch processing strategies strategically

Technical Requirements

Must-Have

Expert-Level SQL

• Complex analytical queries and window functions
• Query optimization and execution plan analysis
• Identifying and eliminating performance bottlenecks
• Reducing query complexity and compute costs
• Designing partitioning and clustering strategies

Python

• Advanced data manipulation

• Amazon S3 (data lake architecture and storage optimization)
• Designing reliable ingestion layers

Version Control

• Git (GitHub / GitLab)
• Branching strategies
• Leading technical code reviews
• Enforcing best practices in code quality

Nice-to-Have

Modern Data Stack

• dbt (modular SQL modeling, documentation, testing)
• Experience structuring layered data models (staging → intermediate → marts)

Data Warehousing

• Google BigQuery
• Slot management
• Cost-efficient querying
• Storage and compute optimization

Advanced Optimization Techniques

• Partitioning

Key Responsibilities

Data Platform Architecture

• Design and maintain a scalable real-time and batch data platform
• Architect ingestion pipelines using AWS Kinesis and Python
• Ensure high availability and reliability of data flows

Real-Time Processing

• Enable near-real-time (seconds–minutes latency) data processing
• Build systems for operational alerting and anomaly detection
• Ensure early detection of monetization and traffic issues

Data Modeling

• Transform raw event data into business-ready datasets using dbt
• Design scalable, maintainable schemas aligned with product evolution

Performance & Cost Engineering

• Optimize SQL queries and storage structures
• Design cost-efficient partitioning strategies
• Monitor and reduce warehouse and infrastructure costs
• Balance real-time and batch processing appropriately

Type of Data We Process

• User behavior events (page views, clicks, searches, conversions)
• Ad & monetization events (impressions, clicks, CTR, attribution)
• System and integration logs (latency, errors, rate limits)

Why Real-Time Is Critical

• Detect broken ads or impression drops before revenue is lost
• Identify traffic anomalies or abuse early
• Enable same-day operational intervention
• Prevent negative user and advertiser experience

Near-real-time (seconds to minutes latency) is required for operational awareness.
Batch processing remains important for historical analysis and reporting — but not for incident detection.

AI–Native Product Team

The Role

As a Senior Fullstack Engineer on one of our new AI–native squads, you will own entire features from database to UI. Our stack runs on AWS with PHP/Laravel and Node.js/NestJS powering the backend services, and React with TypeScript on the frontend. You will be expected to leverage AI coding assistants, automated testing tools, and generative AI workflows as core parts of your daily process—not as occasional novelties.

What you will be responsible for:

• Own and deliver features end–to–end across the full stack (backend services, APIs, frontend interfaces, and data layers)
• Design, build, and operate production systems in a payroll domain where correctness and reliability are non–negotiable
• Use AI coding tools (e.g., Claude Code, Cursor, Copilot) as a daily force multiplier for writing, reviewing, and refactoring code
• Write and maintain automated tests with AI–assisted generation, aiming for high coverage with minimal manual effort
• Participate in lean team rituals: async–first communication, lightweight code reviews, and continuous deployment
• Collaborate closely with product and design in a small squad to scope, estimate, and prioritize work
• Contribute to defining and evolving our AI–augmented engineering practices and toolchain
• Take shared ownership of operational concerns: monitoring, alerting, incident response, and on–call rotations

What We Are Looking For

Must–haves:

• 5+ years of professional software engineering experience with meaningful exposure to both backend (PHP or Node.js) and frontend (React/TypeScript) development
• Strong proficiency in our core stack: PHP/Laravel and/or Node.js/NestJS on the backend, React with TypeScript on the frontend
• Hands–on experience with AWS cloud infrastructure, relational databases, and API design (REST or GraphQL)
• Demonstrated comfort with AI–assisted development workflows—you already use AI tools regularly and can articulate how they change your process
• Strong fundamentals in testing: you know when to write a unit test, an integration test, or lean on AI–generated test suites
• Excellent async written communication—you document decisions, write clear PRs, and can drive alignment without meetings
• Ownership mindset: you do not wait for someone else to write the migration, fix the flaky test, or update the runbook

Nice–to–haves:

• Experience in payroll, HR tech, or fintech domains where precision and compliance matter
• Familiarity with prompt engineering, AI agent frameworks, or building LLM–powered features into products
• Experience migrating or integrating between PHP/Laravel and Node.js/NestJS services
• Experience working in small, high–autonomy teams (startups, platform teams, or similar)
• Background in QA or testing automation—understanding quality from first principles
• Contributions to developer tooling, CI/CD pipelines, or internal platform improvements

Why This Role Is Different

We are not adding “AI” to a job title for marketing purposes. We are restructuring our entire
engineering organization around a thesis: small teams of strong fullstack engineers, deeply
integrated with AI tools, can outperform larger traditional teams in speed, quality, and developer
satisfaction.

What this means in practice:

• You will not hand off work to a separate QA team—you own quality, aided by AI–powered testing and code review
• You will not wait on a backend engineer to build your API—you build the whole feature
• You will have real input into the tools and workflows the team adopts—this transformation is being built collaboratively
• You will work in a team of 2–3, not 5+, which means less coordination overhead and more building time

Benefit offerings include:

• 20 paid vacation days annually
• Paid public holidays based on your country of residence
• Unlimited sick leaves
• Comprehensive premium health insurance coverage
