Get to Know Us. Headquartered in Minnesota, Entrust is an industry leader in identity-centric security solutions, serving over 150 countries with cutting-edge, scalable technologies. But our secret weapon? Our people. It’s the curiosity, dedication, and innovation that drive our success and help us anticipate the future.

The role: We're looking for a Senior Software Engineer to join our Document Fraud team, where you'll build products that delight customers across all our product offerings including financial services, driving verification, proof of address, and much more. Our team builds the fraud detection capabilities that power identity, processing government identity documents to enable secure document verification, fraud prevention, and seamless customer onboarding experiences.

As a Senior Software Engineer on the Document Extraction team, you'll focus on delivering high-accuracy extraction with global document coverage. You'll contribute to our Document Verification offering, helping customers create smooth and secure onboarding experiences. To achieve this, you'll leverage cutting-edge technology including VLM/LLMs and traditional ML approaches in production systems at scale, tackling challenges from designing training and evaluation pipelines, optimising inference for real-time extraction, and integrating as part of our product offering.

What You'll Do:

• Work closely with Applied Science, Product, Design, Data Science, and Operations to deliver highly accurate and performant document classification and extraction solutions across thousands of documents globally.
• Lead the technical design of complex features and systems, taking ownership from RFC through implementation to production deployment.
• Build and optimize production ML systems that matter: develop repeatable pipelines for training, evaluating, and deploying LLM models; implement GPU optimizations for inference; design advanced labeling workflows to improve model accuracy; and engineer robust solutions that deliver measurable customer value through faster processing and more accurate extraction.
• Champion performance, scalability, and reliability by deeply understanding how our systems operate in production.
• Drive technical excellence across the team by leading RFCs, reviewing critical code, holding peers accountable for quality, and making well-reasoned tradeoffs between competing priorities.
• Mentor and enable other engineers through pair programming, technical guidance, and collaborative problem-solving.
• Coordinate solutions to cross-cutting technical problems, working seamlessly across team and organizational boundaries.
• Contribute to a culture of continuous improvement, psychological safety, and collaboration through active participation in our squad-based organization.

What We're Looking For:

• Strong production engineering experience: You've built, deployed, and operated complex systems in production.
• Hands-on LLM/ML systems experience: You've worked with LLMs in production.
• Technical depth and breadth: You're T-shaped—deep expertise in at least one area with broad understanding across software engineering.
• End-to-end ownership: You take complex projects from idea through design, implementation, and production with minimal oversight.
• Tech stack: Our services are primarily Python-based, as well as Ruby and Typescript, everything running on AWS with Kubernetes.
• Strong judgment and initiative: You make sound technical decisions in ambiguous situations.
• Mentorship and collaboration: You enable others to do their best work.
• Pragmatic problem-solving: You identify technical debt and tackle it strategically.
