Senior Software Engineer

Hologram is building the future of IoT connectivity, delivering internet access to millions of connected devices worldwide. We process over 5 billion transactions per month across our global infrastructure—this isn't just another app, it's the invisible backbone powering everything from fleet tracking to smart city infrastructure. We tackle challenges of scale, reliability, and performance that few companies face.

Technical challenges that define careers. Our full-stack engineers solve problems most never encounter: building event streaming systems that handle millions of messages daily, optimizing databases processing terabytes of device data, and creating APIs that maintain sub-millisecond latency at global scale.

Technical ownership with global impact. We're async-first because systems at this scale require deep architectural thinking. When you optimize a database query or redesign an event streaming topology, you're potentially affecting autonomous vehicles, industrial sensors, and smart city infrastructure worldwide.

We look for engineers with insatiable curiosity and an uncompromising commitment to excellence. You're the type who digs deeper when things break, asks 'why' before 'how,' and isn't satisfied until the solution is bulletproof.

Crave genuine technical challenges: You want to solve problems most engineers never face: processing billions of records, ensuring 99.99% uptime, building systems that scale globally

Value tenacious ownership over tasks: You don’t just complete tasks, you immerse yourself in the “why,” define the “what,” architect the “how,” and follow through to meaningful results.

Relentlessly pursue growth: Technology evolves rapidly, and so do we. You embrace new challenges, learn quickly, and help others grow alongside you.

Think like a product engineer: You write code with customer impact in mind, aligning technical decisions with product direction and business context.

Strive for collaborative excellence: You multiply impact through mentoring, cross-functional partnership, and inclusive problem-solving. Great software comes from great teams.

We're seeking two skilled full-stack engineers to tackle complex technical challenges powering the future of IoT connectivity. You'll work with our collaborative team where your technical decisions directly impact how millions of connected devices communicate worldwide.

• Data Pipeline Architecture: Design and optimize systems processing billions of usage records monthly
• Real-time Processing: Build robust backend services using Kafka for high-throughput, low-latency data streams
• Customer Dashboard Features: Develop interfaces presenting detailed status and analytics for thousands of customer SIM cards
• API Development: Create and maintain APIs powering both internal systems and customer integrations
• Full-Stack Solutions: Implement features spanning database optimization to user interface enhancements

Own end-to-end delivery: Lead assigned projects from conception to launch, understanding both the technical "how" and business "why" behind every feature.

Shape product direction: Collaborate directly with product and design teams, using your technical expertise to guide priorities and requirements.

Drive technical excellence: Contribute to architectural decisions that balance existing patterns with innovative solutions for scale while mentoring teammates and elevating overall code quality.
