Position Overview

We are seeking a highly autonomous, systems-fluent, and asynchronous code-proficient Senior Software Engineer to join our core Verification Platform team under a permanent, full-time remote footprint open across Spain, or hybrid out of our Tallinn, Estonia tech hub. In this high-leverage infrastructure seat, you will claim absolute end-to-end design and operational ownership over the central workflow orchestration engine and automated verification decisioning pipelines that anchor Veriff’s global product ecosystem. Shifting completely away from routine non-regulated data transcription loops, entry-level website layout changes, or basic copywriting logs, you will run an active high-throughput distributed message routing, fault-tolerant token processing, and real-time backend API laboratory. Partnering directly alongside cross-functional Identity, Fraud, and End User Platform engineering cells, your work directly determines the scalability and reliability of millions of automated customer onboardings. This position requires a software engineering authority with 5+ years of background who designs data pipelines fluidly natively using Python and distributed infrastructure primitives, manages message queuing nodes, eliminates single points of failure (SPOFs), and thrives inside structured on-call incident response rotations.

Key Responsibilities

• Workflow Orchestration Governance: Design, implement, and operate Veriff’s high-scale backend services, focusing heavily on building the core workflow orchestration engine natively utilizing Python backend practices.
• Decisioning Pipeline Engineering: Deliver critical orchestration features including multi-method execution streams, custom branching logic, dynamic automated fallbacks, and reliable webhook integration nodes.
• Distributed Systems Resilience: Guard production-critical services against traffic surges by implementing sophisticated backpressure controls, idempotency handling, automated retries, and backward-compatibility test layers.
• SPOF Elimination & Triage: Audit distributed system microservices continuously to eliminate single points of failure (SPOFs), establishing ironclad infrastructure boundaries.
• Live Incident Response & On-Call: Participate actively in engineering on-call rotations, directing incident diagnostic assessments and authoring comprehensive blameless postmortems to maintain core pipeline health indices.
• Engineering Quality Stewardship: Drive technical excellence across the platform squad through rigorous code reviews, automated CI practices, scannable runbook documentation, and technical mentorship of junior teammates.
• Observability & Logging Instrumentation: Formulate and integrate structured logging patterns, customized metric alerts, and distributed tracing profiles across database layers.

Required Skills & Qualifications

• A minimum of 5+ years of proven, successful professional history operating within a Senior Backend Engineer, Distributed Systems Architect, Python Platform Developer, Software Engineer - Infrastructure, or closely matching high-scale backend capacity.
• Expert Asynchronous Python Command: Deep, production-grade mastery writing modular logic within event-driven and asynchronous architectures leveraging advanced Python libraries.
• Verifiable history utilizing message brokers, event-driven streaming frameworks, or distributed message queues (specifically Amazon SQS or identical technology models).
• Advanced structural understanding of modular application design patterns, relational database fundamentals, and strict adherence to SOLID principles.
• Outstanding written and verbal communication strengths in English, with an established history explaining complex structural trade-offs clearly to both technical engineers and non-technical stakeholders.
• Location Context: Position operates under flexible parameters open exclusively to qualified backend engineering authorities residing permanently within Spain (Remote) or Tallinn, Estonia (Hybrid/Office) .

Preferred Strategic Indicators (Nice to Have)

• Prior technical or functional architecture background constructing custom state machines, workflow execution engines, or identity verification/fraud detection software layers .
• Familiarity with containerization orchestration fabrics (specifically Kubernetes deployment nodes), microservices mesh networks, or Infrastructure as Code tooling templates.

What We Offer

• Competitive European Tech Platform Compensation: A highly competitive annual remuneration structure calibrated directly to your backend architecture pedigree, supplemented by lucrative corporate stock options to ensure you share in our global success.
• 100% remote workspace infrastructure freedom from your home office across Spain, or modern hybrid-hub access inside our Tallinn tech spaces.
• Venture-Scale Cybersecurity Impact: Elite professional credentials built by commanding the foundational verification and anti-spoofing engine relied upon globally by the world’s most innovative growth companies.
• Comprehensive health preservation benefits, providing extensive medical, dental, and vision insurance packages to optimize your physical and mental well-being.
• Access to extra corporate “recharge days” on top of your generous annual vacation allowance, a tailored annual Learning and Development budget paired with a Health and Sports budget, and four weeks of fully paid sabbatical leave upon celebrating your 5th work anniversary.
