We're building a company at the intersection of payments infrastructure and data products — combining transaction execution with structured financial data that is enriched, explainable, and ready for both operational and AI-driven workflows.

What You'll Be Working On

• You'll own the company's full technical direction: architecture, reliability, delivery, infrastructure, and the people who make it happen.
• Define and drive architectural strategy, introducing clear engineering governance — RFCs, tech radar, vendor evaluation, and practical risk management — without unnecessary bureaucracy.
• Lead the evolution of a high-load, event-driven platform with a focus on scalability, resilience, and fault isolation.
• Own reliability and incident management: observability, SRE practices, incident response, and postmortem culture — with a goal of better uptime, faster detection, and fewer repeated issues.
• Oversee engineering hiring, performance, and development of tech leads; build a culture of end-to-end ownership and accountability.
• Manage cybersecurity protocols, disaster recovery, and business continuity in collaboration with DevOps.
• Drive infrastructure efficiency, cost control, and continuous performance improvement through centralized observability and clear ownership.
• Act as a bridge between engineering teams and executive stakeholders, ensuring technical decisions align with business goals.
• Champion automation, AI integration, and engineering process optimization.
• Design APIs and integration strategies; establish coding, architectural, and infrastructure standards.

What You Need to Succeed

• Proven experience as a CTO, Head of Engineering, or Principal Architect in a high-load SaaS, fintech, or infrastructure company.
• Deep expertise in distributed systems, event-driven architectures, and microservices — including how they behave at scale in production.
• Strong hands-on development background, especially in Go and Python
• Track record of improving reliability, delivery speed, and infrastructure efficiency (uptime, MTTR, MTTD, release cadence, cloud cost).
• Solid understanding of DevOps, CI/CD, SRE, and incident management at scale.
• Comprehensive technical background across architecture, cloud platforms, security, and distributed systems, with a focus on scalability, reliability, and strategic technology leadership.
• Familiar with PCI DSS compliance and secure system design.
• Skilled at hiring and mentoring strong engineers and tech leads.
• Comfortable with vendor evaluation, negotiation, and tooling decisions.
• You understand how engineering decisions affect revenue, risk, and customer trust.

We are looking for a Database Developer / DBA to join our team. You will be responsible for making our data infrastructure reliable and helping it grow. We need someone who has strong technical opinions and knows how to build resilient, high-performance database systems. This role is perfect for someone who prefers working with a focused, high-impact data environment rather than managing a massive amount of data sprawl.

WHAT YOU’LL BE WORKING ON

• Collaborative Infrastructure Design: You will work closely with the DevOps team to suggest and design solutions for our infrastructure. Your role is to provide the architectural vision while working together on implementation.
• High Availability: You will design and maintain replication, failover, and clustering to make sure our systems are always running and fault-tolerant.
• Backups & Disaster Recovery: You will design and test backup strategies to ensure we can restore data quickly with almost no downtime.
• Observability & Monitoring: You will use tools like Prometheus and Grafana to watch our systems, check their health, and set up alerts for any issues.
• Zero-Downtime Maintenance: You will handle routine tasks like patching and vacuuming using blue-green update techniques to avoid service interruptions.
• Automation: You will use Ansible and Terraform to make infrastructure and deployment processes more efficient.
• Architecture & Design: You will lead the planning of our database systems and provide a clear point of view on how to design schemas for better performance.
• Performance Engineering: You will find performance problems and tune queries and indexes based on how the system is being used.
• Development Support: You will work closely with engineering teams to help them optimize queries and plan safe database migrations.
• Security & Access Management: You will manage database security, encryption, and rules for data access.
• Incident Response: You will help find the root cause of database problems and write clear documentation for our systems and recovery steps.

WHAT YOU NEED TO SUCCEED IN THIS ROLE

• PostgreSQL Expertise: You have 4+ years of hands-on experience managing production environments at a terabyte scale, such as a fleet of up to 100 instances.
• Technical Conviction: You have a proven ability to recommend and advocate for the best database setups and high-availability systems.
• Cloud Proficiency: You have experience managing databases in major cloud environments (like AWS, Azure, or GCP) or private/VPS setups. Knowledge in  Amazon Aurora, NoSQL, Columnar DBs, and/or Timeseries is a plus.
• Automation Mindset: You have a strong background in scripting and automation to manage production environments efficiently.
• AI: having the skill to use AI tools to assist with coding or monitoring is a great advantage.

WHAT YOU'LL BE WORKING ON

• Design and development of the core banking system and Internet acquiring service within the financial ecosystem
• Participation in product architecture design and query optimization
• Data handling: synchronization, transmission, and processing
• Implementation of new business logic in applications

• Solid understanding of multithreaded systems and concurrent programming principles
• Strong knowledge of SQL and experience working with relational databases
• Proven experience in developing and maintaining microservice architectures
• Strong understanding and practical application of software development principles: SOA, SOLID, KISS, DRY
• Experience in architectural design and readiness to propose and implement technical solutions
• Familiarity with Clean Architecture principles and Domain-Driven Design (DDD)
• Experience in fintech is a plus, but not required 
• Good written and verbal communication skills in English
