Senior Software Engineer (Back-end/Server)

Headquartered in Vancouver and with strategic hubs in San Diego and Dublin, we foster a culture of collaboration and open communication. Our offices support a hybrid model and staff typically work three days per week at a hub location. Join us where excitement meets innovation and contribute to a world where trust and technology unite.

What We Offer

• Comprehensive Benefits: We provide a robust benefits package for full-time, permanent employees, including health, dental, and vision coverage, retirement plans with company match, paid time off, parental leave, and an annual education & training stipend (equivalent to $1,000 in local currency). Specific benefits may vary by location and will be discussed further during the interview process.
• Flexible Hybrid Working Environment: Our offices are designed to support both collaboration and flexibility. Enjoy weekly lunches, quality coffee, and regular social events. Many locations also feature parent rooms, on-site gyms, comfortable lounges, and adaptable workstations to support your comfort and productivity.
• Wellness: We care about your well-being. Team members have access to wellness workshops and events, as well as a complimentary Headspace subscription to help you stay focused, grounded, and energized.

Position Summary:

Trulioo is looking for a Senior Software Engineer to lead the architecture and development of high-throughput, low-latency back-end services that power our Document and Biometric Verification platform. Reporting to the Senior Manager, Software Engineering, the Senior Software Engineer will design and operate distributed, event-driven microservices that orchestrate real-time identity verification - ingesting captured documents and biometric data, coordinating ML inference and third-party vendor calls, and returning verification decisions at scale across multiple global regions. You will bridge the gap between developer-facing APIs, asynchronous processing pipelines, and the ML and infrastructure systems that sit behind them.

This will be a full-time, permanent position, ideally working out of the Vancouver office on a hybrid model (3-days per week in the office). However, we are open to remote arrangements for the right candidate.

What You’ll Be Doing:

• Service Architecture: Design, build, and maintain secure, modular, horizontally-scalable microservices
• API & Contract Design: Own the gRPC/Protobuf contracts that drive inter-service communication, and the REST/OpenAPI surfaces exposed to external clients, with versioning and backward-compatibility discipline.
• Event-Driven Pipelines: Build robust, high-throughput streaming pipelines on Apache Kafka - designing topics, consumers, and stream-processing topologies to process transaction lifecycle events and coordinate downstream verification steps.
• Data & State Management: Model and optimize data access across distributed NoSQL databases, search/indexing systems, and caching layers; design for consistency, idempotency, and retention/compliance requirements.
• Workflow Orchestration: Implement durable, multi-step verification workflows using a workflow engine to guarantee reliable execution across service and vendor boundaries.
• Performance & Reliability: Drive sub-second end-to-end verification latency and predictable throughput; tune coroutine concurrency, backpressure, and event-driven autoscaling across a wide range of load profiles.
• Technical Leadership: Drive technical architecture, mentor engineers, and collaborate with Machine Learning, Infrastructure, and Product teams to deploy computer vision models and vendor integrations into production.
• Leveraging AI:
• AI-Augmented Engineering: Use AI coding assistants and internal tooling to accelerate service design, implementation, testing, and code review across the microservices platform.
• Intelligent Pipeline Optimization: Apply AI/ML-driven analysis (anomaly detection, log and metrics insight, capacity forecasting) to continuously tune verification-pipeline performance, throughput, and decision logic.

What You’ll Bring:

• 8+ years back-end/server software engineering experience delivering production-grade, distributed services or platforms.
• JVM & Kotlin: Deep proficiency with Kotlin (or strong Java transitioning to Kotlin) and modern JVM concurrency, including Kotlin Coroutines and structured concurrency.
• Microservices & APIs: Hands-on experience building service-oriented or microservice architectures with gRPC/Protobuf and/or REST, including API design, versioning, and inter-service communication patterns.
• Distributed Systems & Messaging: Demonstrated experience with event streaming and asynchronous messaging (Apache Kafka strongly preferred), including consumer scaling, exactly-once/idempotent processing, and failure handling.
• Data Stores: Practical experience with distributed NoSQL databases, search/indexing systems, and caching strategies at scale.
• Cloud Native: Comfortable operating services in a public cloud environment on Kubernetes, with familiarity around containerization, service meshes, and infrastructure-as-code.
• Resource Optimization: Demonstrated expertise managing memory, thread/coroutine concurrency, connection pooling, and payload optimization for high-throughput, latency-sensitive workloads.
• AI Expectations:
• AI-Assisted Development: Hands-on daily use of AI coding assistants (e.g., GitHub Copilot, Claude Code, Cursor) to accelerate design, implementation, testing, and code review.
• Critical Evaluation: Ability to critically assess AI-generated code and outputs for correctness, security, and performance before it reaches production.
• Applied AI/ML Literacy: Working understanding of how LLMs and ML models behave in production (latency, cost, failure modes) sufficient to reason about AI-driven components in a backend system.

It’s a bonus if you have…

• Identity Verification: Experience with IDV (Identity Verification), KYC systems, or integrating with biometric liveness/anti-spoofing and document-authenticity engines.
• Workflow & Orchestration: Familiarity with durable workflow engines (Temporal, Cadence, or equivalent) for coordinating long-running, multi-service processes.
• ML Integration: Experience serving or integrating ML models into back-end services (e.g., Deep Java Library, PyTorch, ONNX, or TensorFlow) and orchestrating third-party vendor APIs.
• Observability & Ops: Experience with modern observability tooling (metrics, logs, and distributed tracing via OpenTelemetry) and running multi-region production services.
• DevOps/CI: Experience with CI/CD pipelines, containerized builds, Helm-based Kubernetes deployments, and secrets management.
