Coder Jobs in Alberta (NOW HIRING)

Billing is one of the most consequential touchpoints a customer has with TELUS - and one of the least loved. Our ambition is to change that: to reimagine billing as something customers actually trust, where their bill is clear, accurate, and never a source of frustration or doubt.

That means more than modernizing the technology. It means rethinking the systems, processes, and engineering practices that sit behind every invoice, every account interaction, and every payment - calculating charges, generating bills, managing accounts, and reconciling revenue across millions of customers. The estate is complex, largely 20+ years old, and under active transformation.

As an L5, you are the senior engineering presence across the billing domain - hands-on technically, and accountable for elevating the engineers around you. You report directly to the Director in the Billing Revenue Management domain, operate across multiple teams without direct reports, and influence through credibility and craft.

What you'll do

Hands-on billing engineering 

• Design, build, and operate systems across the billing lifecycle: charge calculation, invoice generation, account management, network mediation, usage charging, and payment processing
• Decompose and mordernize application components into maintainable, internally-owned services - reducing technical debt and improving system reliability
• Ensure accuracy, auditability, and reconciliation across billing workflows; own the quality bar for your subsystems
• Debug and resolve complex cross-system issues in production; lead root cause analysis and implement durable fixes
• Operate with ownership: stay close to the code, monitor system health, and respond to production issues
• Prototype new ideas and solutions, review and improve design and code across the teams

• Use AI development tools daily as part of your coding workflow - code generation, test coverage, code comprehension, documentation
• Experiment with AI-assisted approaches to billing problems (e.g., using LLMs to understand code, accelerating test writing)
• Share learnings with your team about what works and what doesn't; help teammates adopt tools that genuinely improve their delivery

Coaching & mentoring 

• Mentor junior or mid-level engineers on the team; grow their billing domain expertise and engineering judgment
• Run code reviews as learning opportunities - provide constructive feedback, explain the "why" behind standards, and help engineers understand trade-offs
• Pair program on complex problems; transfer knowledge directly through hands-on work
• Lead occasional design discussions or post-incident reviews where the team learns together
• Build internal documentation (wikis, playbooks, runbooks) to reduce reliance on vendor expertise and make billing knowledge accessible to the team

Charging & Mediation integration

• Own integration quality between upstream charging and mediation systems that feed the billing pipeline
• Debug cross-system issues; ensure data flows accurately from charging through to billing
• Provide input on system design decisions that affect downstream billing workflows

• 7+ years hands-on engineering with production ownership of complex, high-volume systems
• Demonstrated comfort working in  environments; you reduce ambiguity rather than avoid it
• Strong foundation in distributed systems: eventual consistency, event-driven architecture, high-availability design
• Experience with billing, financial, or revenue systems is a strong asset
• Cloud-native fluency on GCP (Kubernetes, Pub/Sub, Dataflow, BigQuery, Cloud SQL) and IaC/DevOps practices
• You genuinely enjoy helping other engineers grow - through code reviews, pairing, design discussions, or documentation
• Ability to explain complex concepts clearly and help engineers develop both technical depth and ownership mindset
• Experience mentoring junior or mid-level engineers (doesn't need to be formal; could be peer mentoring, tech lead experience, or guild leadership)
• Hands-on engineer who stays close to the code and the systems you own - not delegating away the interesting problems
• Operates with ownership and transparency - surfaces problems early, shares context freely, builds trust through consistent delivery
• Comfortable learning new domains quickly; billing may be new to you, but you pick up complex systems rapidly
• Open to experimenting with AI development tools; comfortable integrating them into your workflow without needing to be an expert first

Great-to-haves

• Direct experience with various vendor billing platforms
• Background in telecom, utilities, or regulated billing environments
• Experience mentoring engineers at a company or within a technical guild/community
• GCP Professional certifications (Cloud Architect, Data Engineer)
