Description
We are looking for a Principal Engineer to help scale our engineering organization, reduce system complexity, and define a sustainable technical direction, building on top of a mature and evolving platform.
You will operate at the system level, working across teams and domains to align architectural decisions, improve engineering practices, and address long-term technical risks. Partnering closely with senior engineers, tech leads, and engineering leadership, you will help turn technical vision into clear principles, shared standards, and sustainable solutions.
This role calls for a highly experienced technical leader with strong system thinking, sound engineering judgment, and the ability to influence without formal authority. You are comfortable navigating ambiguity, making trade-offs, and engaging in constructive technical debate — always with a focus on long-term impact rather than short-term wins.
If you want to shape the technical future of an organization, and tackle complex architectural challenges at scale, this role is for you.
Challenges that await you:
- Defining and maintaining company-wide architectural principles
- Aligning technical decisions across teams and domains
- Identifying and reducing architectural and organizational complexity
- Leading RFCs, architecture reviews, and design discussions
- Influencing technical decisions
- Participating in major incident analysis and systemic problem solving
What makes you a great fit:
- Experience in a large engineering organization (300+ engineers)
- Hands-on experience with complex distributed systems
- Proven impact on architectural decisions beyond your own team
- Experience with architectural mistakes, refactoring, and incidents
- Strong system-level thinking and understanding of trade-offs
- Clear communication and ability to work through disagreement
Our ways of working:
- Innovative Spirit: A commitment to creativity and groundbreaking solutions
- Honest Feedback: valuing open, transparent communication\
- Supportive Team: a strong, collaborative community
- Celebrating Achievements: recognizing our wins together
- High-Tech Environment: a team full of smart and revolutionary people who date to challenge the status quo of incumbent finances
Our benefits:
- Relocation support to one of our hubs — Cyprus, Georgia, Serbia or Spain — with assistance for the employee and their family
- Flexible work from one of our offices or remote
- Healthcare Coverage
- Education Budget: Language lessons, professional training and certifications
- Wellness Budget: Mental health and fitness activity reimbursements
- Vacation Policy: Annual leave and paid sick leave as per applicable policies
Benefits
- sick leave
About this role
Plata Card is seeking a Principal Engineer to lead technical strategy and architecture across a scaling engineering organization. You'll work at the system level, partnering with senior engineers and leadership to define architectural principles, align decisions across teams, reduce complexity, and address long-term technical risks. This is fundamentally a role about influence—shaping how the organization builds, thinks about trade-offs, and solves problems sustainably, rather than hands-on coding.
You'll need substantial experience in large engineering environments (300+ engineers), deep familiarity with distributed systems, and a track record of driving architectural decisions beyond your own team. The role demands strong system thinking, sound judgment under ambiguity, and the ability to navigate disagreement constructively. You should be comfortable leading design discussions, RFCs, and architecture reviews, and drawing lessons from incidents and refactoring efforts to inform future direction.
The position is based in Sydney and requires in-office presence. Plata Card offers relocation support to hubs in Cyprus, Georgia, Serbia, or Spain if needed, alongside healthcare coverage, education and wellness budgets, and 20 days of annual leave. This suits someone ready to shape a technical organization's future and tackle architectural challenges at scale.
