Senior Software Engineer

About Webbula

At Webbula, we are dedicated to one core principle: Truth in Data. Since 2009, we have been the industry leader in Data Hygiene, Data Appends, and Audience Targeting. We don’t just guess; we use deterministic, self-reported data to help the world’s biggest brands (and their Data Management Platforms) avoid fraud, mitigate delivery threats, and truly understand their customers.

We are a tight-knit team based in Wexford, PA, solving massive challenges. We process millions of data points daily to separate valid customers from bots, spam traps, and malicious actors.


The Mission

We are looking for a Senior Software Engineer who loves high-volume data and scalable architecture. You won’t just be building CRUD apps here. You will be working on the core engines that power CloudHygiene and our real-time API services. You will help us ensure that when a client asks, “Is this email safe?”, we answer with 100% accuracy and millisecond latency.


Key Responsibilities

• Core System Development: Design and implement robust backend services that power our email verification and data append APIs.
• Data at Scale: Optimize algorithms for processing, matching, and cleaning massive datasets (Big Data) in real-time.
• Architecture: Contribute to the evolution of our tech stack, moving from monolithic services to scalable, cloud-native microservices where appropriate.
• Security & Compliance: Write secure code that adheres to SOC 2 standards and ensures strict PII data governance.
• Mentorship: Act as a technical lead for mid-level engineers, conducting code reviews and driving engineering best practices.
• Innovation: Collaborate with our Data Science team to implement new methods for fraud detection and “truth” scoring.


Bonus Points (Nice to Have)

• Experience with Python (often used here for data analysis scripts).
• Background in AdTech, MarTech, or Cybersecurity.
• Knowledge of Docker and Kubernetes.
• Understanding of email protocols (SMTP, DNS, MX records).

Why Join Webbula?

• Impact: Your code directly protects the reputation of Fortune 500 companies.
• Culture: A collaborative, “no-ego” environment where the best idea wins. We are passionate about what we do, but we value work-life balance.
• Growth: Opportunity to work directly with leadership (COO/CTO) and shape the technical direction of the product.
• Benefits: Competitive salary, comprehensive healthcare, 401(k), and a modern office environment in Wexford.
