Senior Backend Developer (Python).

Who we are:

Adaptiq is a technology hub specializing in building, scaling, and supporting R&D teams for high-end, fast-growing product companies in a wide range of industries.

About the Product:

We power a B2B open finance infrastructure platform that aggregates financial data and initiates payments across institutions, enabling services like real-time underwriting, bank-to-bank transfers, and portfolio analytics.

Operating in a single market with plans for international expansion, the platform handles large-scale data ingestion, event-driven processing, and transaction routing for banks, fintechs, insurers, and retailers, meeting regulatory open finance requirements.

Engineers work on high-throughput processing, low-latency APIs, distributed microservices, and enterprise-grade security in a highly complex environment.

About the Role:

We are seeking a Senior Backend Engineer who can design and own backend systems end-to-end, mentor other developers, and handle production Kubernetes environments.

You will collaborate with product and engineering, guide technical direction, mentor others, and help shape best practices in microservices, event-driven architecture, and cloud-native systems.

Key Responsibilities:

• Architect and implement core backend features using Python, Django, and Celery.
• Design and maintain RESTful APIs and event-driven microservices for data exchange and payment initiation.
• Model, query, and optimize complex datasets in PostgreSQL.
• Deploy, monitor, and troubleshoot services on Kubernetes in AWS (and on-prem OpenShift environments).
• Drive technical designs: define data schemas, service contracts, and CI/CD pipelines.
• Collaborate with product managers to refine requirements and translate them into scalable solutions.
• Mentor and review work of junior and mid-level engineers; share domain knowledge.
• Participate in on-call rotation and incident response to maintain high availability.
• Contribute to lightweight React front-end adjustments when backend integrations require UI support.
• Help set standards, frameworks, and patterns for future development.

• Proven expertise in Django, building backend applications and APIs
• Proven experience with Celery (or equivalent task-queue frameworks) 
• Strong background in designing and consuming REST APIs and event-driven microservices.
• Production experience with Kubernetes on AWS.
• Deep knowledge of PostgreSQL – data modeling, indexing, query optimization
• Hands-on with cloud-native services and serverless functions (e.g., AWS Lambda).
• Solid understanding of CI/CD practices and infrastructure as code.
• Experience in diagnosing and resolving performance and reliability issues in high-traffic systems.
• Fluent in English, with strong written and verbal communication skills

Nice to Have:

• Experience with Oracle databases or Node.js services.
• Prior work with React for lightweight front-end tasks.
• Familiarity with OpenShift.
• Familiarity with on-prem deployments and integration with corporate environments.
