We combine global reach with a mindset focused on agility, senior expertise, and close collaboration. We work as an extension of our clients' teams, helping them define the right problems, shape solutions, and deliver technology-driven outcomes that create measurable business value. Our expertise spans software engineering, AI & data, product development, and customer experience, delivered by teams that combine strong technical depth with a consulting mindset.
Why Join Us? If you are looking for a place where you can think beyond execution, take true ownership of outcomes, influence decisions, and continuously learn alongside top-tier specialists in a truly global environment, we'd love to meet you.
How will you impact? As a Principal Engineer at Parser, you will partner with a long-established leader in the global payments industry to define and launch a next-generation onboarding solution for its clients. You will drive the architecture, reliability, and engineering direction of critical financial platforms, shaping an onboarding engine platform that enables seamless integration through a new SDK framework. Working in an ambiguous space, you will play a critical role in product discovery and early product definition, designing and testing early concepts to translate complex user needs and data into clear, intuitive, and high-value experiences that accelerate client onboarding.
Your key responsibilities:
- Technical Strategy & Architecture: Co-own product squads alongside Product Managers and design distributed, cloud-native, and event-driven systems (e.g., using Kubernetes, Kafka, or microservices).
- Hands-on Engineering Leadership: Stay close to the code by pairing on complex problems, reviewing critical changes, and unblocking delivery.
- Regulatory & Risk Governance: Build secure-by-design, resilient, and auditable systems that meet strict financial regulations, anti-money laundering (AML) controls, and data protection standards.
- Modern Engineering & AI Integration: Champion CI/CD optimization, automated testing, and emerging practices like AI-assisted software delivery or agentic engineering workflows while keeping human-in-the-loop governance.
- Coaching & Influence: Mentor engineers across teams, align platform standards with Security, QE, and Risk/Audit, and influence technical roadmaps without necessarily holding direct line-management authority.
- Product Discovery & Integration Modeling: Help define how clients are onboarded and integrated, how complex data is surfaced and compared, and what the most effective integration model looks like.
What you'll bring to the role:
Essential Requirements:
- Experience: Extensive software engineering background (often 8+ years) with proven principal- or staff-level technical leadership in agile, product-led, or regulated financial environments.
- Domain Knowledge: Deep familiarity with core banking workflows (ledger systems, interest calculations, posting engines), payments rails, or digital assets/blockchain depending on the team.
- Tech Stack Proficiency: Strong command of backend languages (e.g., Java, Rust, Go), cloud platforms (AWS, Azure), container orchestration (Kubernetes), and relational/distributed databases.
- Risk & Resilience Mindset: Track record of designing systems with high availability, disaster recovery, and clear failure-mode analysis for real-money transactions.
