Job summary

Apptoza Inc. in Toronto is seeking a senior Forward Deployed Engineer who blends production-grade software engineering, data engineering, AI application development, and client-facing consulting to embed with business users and engineering teams.

You will map workflows, validate solutions with real data, design end-to-end pipelines, and own delivery from prototype to production, with focus on performance, reliability, and business impact.

Qualifications

• Bachelor's degree in a relevant discipline.
• Cloud, Kubernetes, AI engineering, MLOps, data engineering, architecture, or security certifications preferred.
• BFSI experience and strong client-facing skills across discovery, rapid prototyping, solution shaping, workshops, and technical presentations.

Responsibilities

• Embed with client SMEs, product owners, business users, and engineers to map workflows, users, data, constraints, and decision points.
• Agree on the first useful release, measurable success criteria, and a practical roadmap from prototype to production.
• Profile unfamiliar client data using Python, pandas, PySpark, and SQL to assess coverage, quality, volumes, distributions, edge cases, and feasibility.
• Build thin working solutions using real client data and APIs, validate them with users, and iteratively harden them for production.
• Design, develop, and deploy enterprise AI and data applications using Python, PySpark, SQL, REST APIs, FastAPI, and cloud data platforms.
• Build Claude-powered applications, copilots, and AI workflows using prompt engineering, RAG, vector databases, semantic search, and agentic AI patterns.
• Design batch, real-time, and streaming data pipelines and integrations across enterprise systems.
• Implement MLOps/LLMOps capabilities, including lifecycle management, CI/CD, MLflow, monitoring, deployment automation, rollback, and production support.
• Create evaluation datasets with client SMEs, measure model and LLM quality, perform structured error analysis, and prioritize improvements.
• Resolve data-access, API, identity, network, security, infrastructure, and deployment blockers with client teams.
• Own post-go-live monitoring, incident diagnosis, rollback, stabilization, latency, performance, reliability, and cost optimization.
• Measure adoption and business impact using agreed KPIs, then complete structured handover with runbooks, support ownership, and knowledge transfer.

The opportunity

We are looking for a senior Forward Deployed Engineer who combines production-grade software engineering, data engineering, AI application development, and client-facing consulting. You will embed with business users, client SMEs, product owners, and engineering teams to understand complex workflows, rapidly validate solutions using real data, remove technical blockers, and own delivery through production launch, stabilization, adoption, and handover.

What you will do

• Embed with client SMEs, product owners, business users, and engineers to map workflows, users, data, constraints, and decision points.
• Agree on the first useful release, measurable success criteria, and a practical roadmap from prototype to production.
• Profile unfamiliar client data using Python, pandas, PySpark, and SQL to assess coverage, quality, volumes, distributions, edge cases, and feasibility.
• Build thin working solutions using real client data and APIs, validate them with users, and iteratively harden them for production.
• Design, develop, and deploy enterprise AI and data applications using Python, PySpark, SQL, REST APIs, FastAPI, and cloud data platforms.
• Build Claude-powered applications, copilots, and AI workflows using prompt engineering, RAG, vector databases, semantic search, and agentic AI patterns.
• Design batch, real-time, and streaming data pipelines and integrations across enterprise systems.
• Implement MLOps/LLMOps capabilities, including lifecycle management, CI/CD, MLflow, monitoring, deployment automation, rollback, and production support.
• Create evaluation datasets with client SMEs, measure model and LLM quality, perform structured error analysis, and prioritize improvements.
• Resolve data-access, API, identity, network, security, infrastructure, and deployment blockers with client teams.
• Own post-go-live monitoring, incident diagnosis, rollback, stabilization, latency, performance, reliability, and cost optimization.
• Measure adoption and business impact using agreed KPIs, then complete structured handover with runbooks, support ownership, and knowledge transfer.

What you bring

• 10+ years of experience in data engineering, AI application development, cloud data platforms, and production software engineering.
• Strong hands-on expertise in Python, PySpark, SQL, REST APIs, FastAPI, Git, Docker, Kubernetes, Airflow, MLflow, CI/CD, and distributed processing.
• Experience with Claude, prompt engineering, RAG, vector databases, semantic search, and agentic AI patterns.
• Strong knowledge of ETL/ELT, batch and streaming pipelines, data quality, metadata, lineage, observability, and DataOps.
• Experience operationalizing MLOps/LLMOps, including model lifecycle management, automated deployment, monitoring, rollback, and production support.
• Knowledge of enterprise cloud services across compute, storage, integration, orchestration, networking, monitoring, security, and cost optimization.
• Understanding of IAM/RBAC, encryption, secrets management, privacy controls, auditability, compliance, and secure data access.
• Ability to translate business requirements into scalable designs, define non-functional requirements, estimate effort, and drive implementation.
• BFSI experience and strong client-facing skills across discovery, rapid prototyping, solution shaping, workshops, and technical presentations.
• Bachelor's degree in a relevant discipline. Cloud, Kubernetes, AI engineering, MLOps, data engineering, architecture, or security certifications are preferred.
