Who we are

Adaptiq is a technology hub that helps fast-growing product companies build, scale, and support strong R&D teams across different industries.
 

About the Product

We are developing an AI-first maritime intelligence platform that combines multiple global maritime data sources into one operational view. The product creates a digital twin of worldwide maritime activity and uses behavioral analytics, predictive AI models, and advanced data processing to detect risks such as smuggling, illegal fishing, container threats, and other compliance or security issues.

The platform is used by commercial, regulatory, and government customers, operating at global scale and processing millions of events along with terabytes of geospatial data every day. It is built on cloud infrastructure, microservices, and close integration with research and data science prototypes.
 

About the Role

As a Senior Backend Python Engineer, you will join an autonomous team focused on building and scaling agentic, AI-first workflows within a production-grade maritime intelligence platform.

You will be responsible for designing, delivering, and operating backend services that support generative AI agents at scale. The role involves influencing architecture, improving AI-SDLC practices, and helping shape agent-based automation used in real-world defense, regulatory, and enterprise scenarios.
 

Key Responsibilities

• Design and develop scalable Python-based microservices for agentic workflows, data pipelines, and distributed systems.
• Contribute to frontend development with React when needed.
• Integrate generative AI capabilities into production systems, including LLM APIs, RAG pipelines, and autonomous agents.
• Build operational practices and observability for AI components, including monitoring for model drift, hallucinations, and performance metrics.
• Implement and improve AI-SDLC standards, including code reviews, automated testing, CI/CD pipelines, and trace-based quality evaluation.
• Design and maintain infrastructure as code using Terraform, Kubernetes, and AWS services.
• Improve engineering velocity and product quality through automation, tooling, and architecture improvements.
• Mentor engineers on AI frameworks, developer tools, and best practices for high-scale agentic development.
• Work closely with product and research teams to turn user needs into reliable, secure, and scalable backend services.
   

Required Skills and Experience

• 7+ years of professional backend engineering experience.
• At least 2 years of experience building agentic or autonomous AI workflows in production.
• Strong hands-on experience with Python.
• Practical experience with agentic frameworks such as LangChain, LangGraph, DeepAgents, CrewAI, OpenClaw, Hermes, or similar.
• Proven experience designing scalable, event-driven architectures on AWS.
• Experience with messaging systems such as SQS/SNS and SQL/NoSQL databases.
• Strong understanding of GraphQL or REST API design.
• Solid DevOps background, including CI/CD, Kubernetes, and Terraform.
• Experience with production-grade security, monitoring, and incident response for mission-critical systems.
• Strong communication skills, autonomy, ownership, and ability to work in fast-paced, ambiguous environments.
   

Nice to Have

• Experience with React.js or full-stack development.
• Familiarity with vector databases and similarity search for AI applications.
   

Why Us

• 20 vacation days per calendar year, plus official national holidays in the country where you are based.
• Full accounting and legal support in all countries where we operate.
• Fully remote work model.
• Powerful workstation provided.
• Co-working space support if needed.
• Competitive compensation package with annual performance and salary reviews.

Requirements:

• Strong backend development experience with C++ (the bulk of the backend is built on a custom in-house framework)
• Hands-on experience with AWS, particularly S3
• Proficiency with Protobuf
• Experience deploying and operating services on Kubernetes, including performance-driven traffic routing to pods
• Performance engineering skills — hash-based routing, SSD-based caching, and memory-mapped files
• Solid systems / low-level fundamentals (there is no off-the-shelf framework to rely on — much of the stack is custom)
• Ability to work highly autonomously and drive work forward with minimal supervision
• Strong communication skills and experience working in distributed teams (Europe/Ukraine time zone; ~1–2 hours of daily overlap with a US-based team)
• Hands-on experience with AI-assisted development tools — e.g. Claude Code and Codex — including AI skills, plugins, and MCP (Model Context Protocol), with a clear understanding of how to boost personal productivity and code quality using AI tooling

Nice-to-Have:

• Familiarity with OpenTelemetry / observability tooling
• Understanding of LevelDB SSTable concepts and sorted, time-keyed data structures
• Familiarity with Python (used only for a small metadata/auth service)
• Basic DevOps skills

Key Responsibilities:

• Optimize the performance of the C++ data-streaming backend — efficient delivery of large recorded datasets to the browser
• Work on infrastructure-level optimizations: traffic routing to Kubernetes pods, hash-based routing, SSD-based caching, and memory-mapped files
• Operate within a custom data-handling stack — a C++ framework, a custom HTTP server, and a proprietary data format built on top of LevelDB SSTables and Protobuf
• Take ownership of performance work end-to-end, proactively identifying bottlenecks and driving solutions independently
• Collaborate with a primarily US-based team with ~1–2 hours of daily overlap, while working largely independently
• Participate in code reviews and design discussions

About the Project:

You'll join the engineering team of a leading technology company building autonomous mobility and robotics systems. The team develops an internal data visualization platform — a "video and data player" that renders 3D scenes, lidar, and audio recorded by autonomous vehicles. This role sits on the performance work stream: the backend reads on-vehicle data stored in S3, deserializes it from a custom, time-keyed format, and streams it to the browser. The data-transfer service is implemented in C++, and most of the platform's performance gains are expected to come from the backend.

This is a long-term engagement for a strong systems engineer who enjoys low-level performance work and is comfortable ramping on a heavily custom stack with high ownership and minimal supervision.
