Senior Systems Architect in Oakville

The Platform & Enterprise Technology team at Euna Solutions sets the architectural foundation that every product in the portfolio runs on, and this role owns that foundation. As Senior Architect, you will define the standards, patterns, and technical direction for cloud infrastructure, identity, integration, shared services, and the enterprise systems that tie them together, then stay close enough to delivery to make sure those patterns hold. If you want to own the horizontal layer that makes a multi-product software company work at scale, this is the role for you.

What You'll Do

• Own the architecture and technical direction of the shared platform layer, including service boundaries, contracts, and how products consume shared capabilities.
• Govern Euna's technical standards program end-to-end: drafting, reviewing, ratifying, communicating, and keeping standards current across architecture, engineering, and operations.
• Define cloud architecture patterns for multi-account structure, network topology, workload isolation, and resilience, in close partnership with Cloud Operations and SRE.
• Set architectural direction for identity and access management across both product and corporate systems.
• Align architectural decisions with the Security team to meet public sector compliance obligations, including SOC 2, PCI DSS, and GovRAMP.
• Identify high-risk and high-impact work across the estate, make the business case, and define the sequencing for addressing it.
• Advise the AI team and participate in the Architecture Review Board on cross-cutting infrastructure, identity, and integration decisions.

What You Bring

• 10+ years in technology, including 5+ years in architecture or staff-level roles, with a hands-on background in cloud, infrastructure, or IT engineering at production scale.
• Deep experience in cloud architecture at organizational scale: multi-account AWS environments, networking, workload isolation, and shared services, with working fluency in Azure.
• Hands-on proficiency with Terraform or equivalent infrastructure as code, sufficient to stay credible in technical design conversations.
• Strong background in identity and access architecture, including OAuth2, OIDC, SAML, and SCIM.
• Demonstrated experience owning a technical standards or governance practice that spans teams you do not manage, including gathering practitioner input and keeping published guidance current.
• Proven ability to lead through influence, building consensus among senior technical people and bringing engineers and executives to a decision through clear, concise written and verbal communication.

Nice-to-Have Qualifications

• Experience integrating technology estates following an acquisition.
• Experience with centralized AI capability delivery, including model access patterns, data handling, and technical guardrails.
• FinOps practice experience and familiarity with cloud cost accountability frameworks.
• Public sector or govtech domain experience, or a cloud architecture certification at the professional or expert level (AWS Solutions Architect Professional, Azure Solutions Architect Expert, or comparable).

Location

This position will be hybrid with 3 days/week in our Oakville, ON office.

Compensation Range

$127,600 - $159,500. We believe in openness, so we publish our range from the start. Where an offer will land depends on your background, strengths, and how you'll contribute to the work ahead.

AI Mindset at Euna Solutions

We believe the future of work is human + AI. At Euna Solutions, we encourage our team members to leverage AI tools to enhance creativity, efficiency, and decision-making. We're looking for people who are curious about emerging technologies, eager to experiment, and committed to using AI responsibly to augment, not replace, their expertise.

Life at Euna Solutions

We're a team of builders, problem-solvers, and public sector champions. We've built a workplace around a straightforward idea: people do their best work when they're trusted, supported, and not running on empty.

How we work

We're hybrid — three days a week in our Oakville or Atlanta offices, with standard hours on those days. What the remaining days look like depends on your role and your manager. We talk about it early in the process so there are no surprises on either side.

Eunafier Days

Twice a year, you get an extra day tacked onto a long weekend. We think recharging is part of doing good work — not a reward for it. Use it however you need.

Community is part of who we are

Our Engagement Committee finds meaningful ways to give back through time, donations, and shared expertise. We're invested in the places where our people actually live and work.

Philanthropy Time

We give every employee up to eight hours a year to spend on causes that matter to them. We want you to show up for your community — and we make time for it.

Real connection at scale

You won't know all 600+ people — and that's okay. What matters is building real relationships with the people you work with every day. Our culture team creates consistent opportunities for that, so work does not feel isolating.

Room to grow

Whether you're going deep on AI, building expertise in government tech, or stepping into a bigger role, we invest in your development — through budget, mentorship, and real opportunity to move when you're ready.
