Jobs at Djinni

We're looking for a Lead Python Engineer who will be the key developer on the team - someone who has already designed architecture, not just built against someone else's.

If an e-commerce site goes down, it's inconvenient. This product has to run without failure: if a software glitch shuts down a 50 MW plant, that means direct financial losses and safety risks. Your code moves megawatts, not pixels or shopping carts.

About the company

A European energy company that builds and operates power plants: solar, wind, and industrial-scale battery energy storage systems.

• Our own EMS platform started as an internal tool and is now being turned into a standalone product for any plant owner or energy service company
• The product is at MVP stage

What you'll do

• Take over the platform, together with a small team (a Md Django engineer is already on board)
• Run a technical audit of the MVP
• Design and implement failover for plant connections: reconnect, buffering, redundancy - so telemetry and commands survive unreliable 4G links
• Build agentic pipelines to automate development, testing and deployment, and make Spec-Driven Development a mandatory standard
• Work in two modes: Rapid Validation (shipping lean features to test hypotheses) and Stabilization (hardening what shows traction)
• Do technical pruning: remove dead code and features behind hypotheses that didn't work out
• Set engineering standards: code review, branching, CI gates (ruff, pytest), definition of done. The API has to stay stable for a dispatch center that runs 24/7

Who we're looking for

• 8+ years of production Python experience
• The full stack in production: Django + DRF, FastAPI (Pydantic v2), Celery, PostgreSQL, Redis, Docker / Docker Compose, pytest + CI
• API and system architecture design: service boundaries, contracts, data flows - not only implementing against someone else's design
• RBAC: role models on the principle of least privilege, DRF permissions, object-level access, access enforced consistently across services
• Integrating external APIs behind a caching layer (Redis): cache strategy and invalidation, rate limits, retries/backoff, serving stale data gracefully when the upstream is down
• Failover thinking: reconnect strategies, buffering, health checks, redundancy, graceful degradation over unreliable links
• Spec-Driven Development: contract-first (OpenAPI/Swagger, Pydantic, gRPC), specifications as the source of truth for AI agents
• Agentic pipelines: CrewAI, LangGraph or custom orchestrators, automating engineering workflows
• English B2+

Soft skills

• Product mindset. We need someone who treats the platform as their own product, not as another outsourcing project. Code is a temporary asset until the business model is validated
• Ownership. The result is production, not a PR
• Ability to explain an architectural decision to a non-engineer, and to stay calm during incidents

We are DRCT — a travel-tech product company building SaaS solutions for the aviation industry. We help travel agencies and airlines access flight content more easily, automate workflows, and increase profitability through modern technology.
 

Since 2016, we’ve grown from a Ukrainian startup into an international group of companies operating across Poland, Saudi Arabia, the Baltics, and other European markets.
 

Now we are looking for someone to join our team and take an active role in growing our presence in the Polish market.
 

What you will do:

Requirements:
 

• Polish advanced speaking skills: 
  You can confidently communicate with clients in Polish and clearly deliver value.
• Based in Warsaw:
  You are currently located in Warsaw and available for in-person meetings with customers.
• 1-2 years of experience in outbound sales:
  You know where to find leads, how to approach them, and feel confident in outbound — it motivates you rather than drains you.
• Strong ownership mentality: 
  You`re able to take responsibility for your actions, leads, and performance. You care about the final result, not just completing tasks.
• Active and high-energy: 
  You are easy to talk to, build rapport quickly, and bring positive, confident energy into every interaction.
• Interested in the aviation field:
  You are curious about the aviation industry, care about what you sell, and are ready to learn a complex product domain.
• Fast learner and self-educator:
  You quickly deep dive into new topics, independently search for answers, and adapt fast in complex environments.
• Highly responsible and disciplined:
  You can take responsibility and pay attention to detail.
• Communicative and empathetic:
  You can deeply understand the problems each client is facing and address them with a personalized approach.
   

Will be a big plus:
 

• Ukrainian advanced speaking skills.
• Passion for startups and technology.
• Experience in the aviation ticketing field (GDS, NDC).
   

What We Offer
 

• Enjoy a remote-friendly role with the possibility to work remotely, participate in industry events, meet clients in person, and use our co-working space in Warsaw whenever needed.
• Small, agile team — work in a fast-growing company where your ideas truly matter.

About the client

Our client is developing technology to make industrial environments safer and reduce the risk of accidents through proactive monitoring.

The Ukrainian engineering team is building a next-generation industrial safety platform combining Computer Vision, Machine Learning and IoT.

About the role

We are looking for a Middle Systems / Software Engineer to work on the performance-critical core of a real-time Computer Vision platform.

This is not a typical Python Backend role. The main challenge is building and optimising the systems underneath the CV/ML engines — where performance depends on memory, processes, concurrency, data movement, CPU/GPU utilisation and low latency.

You will work on the runtime that executes CV pipelines as a graph of processing stages, with latency measured in milliseconds. You will deal with shared memory, zero-copy data transfer, inter-process communication and process orchestration.

What matters most to us

We are open to engineers coming from C++, Python, Go or similar backgrounds.

The programming language itself is not the main selection criterion. What matters much more is a strong systems engineering mindset and experience understanding what is happening inside a system.

For example, we are particularly interested in engineers who have worked with problems such as:

• reducing unnecessary memory copies;
• optimising CPU/GPU utilisation;
• investigating latency spikes and performance bottlenecks;
• working with processes, threads and concurrency;
• debugging race conditions and difficult low-level issues;
• profiling applications and identifying bottlenecks;
• designing efficient data-processing pipelines;
• working with large amounts of data moving through several processing stages;

• optimising algorithms or runtimes for performance.

   

A candidate does not necessarily need to have worked with exactly the same technologies before.

For example, experience with CUDA, C++, GPU optimisation, real-time processing, robotics, computer vision, video pipelines, scientific computing or other performance-sensitive systems can be highly relevant.

What you’ll work on

• Collaborate with CV/ML engineers to turn model inference code into reliable production pipeline stages.
• Develop and optimise the core Pipeline Engine — an in-process, real-time runtime executing the CV pipeline as a graph of stages.
• Work with zero-copy shared-memory pools for passing frames between processes.
• Develop and optimise low-latency ZeroMQ communication for control messages, metadata and synchronisation.
• Work with pipeline metadata and serialisation boundaries.
• Analyse and improve CPU, memory and latency performance.
• Profile, debug and troubleshoot complex runtime issues.

• Contribute to the architecture and evolution of the real-time processing infrastructure.

   

Requirements

Must-have

• Commercial experience as a Software Engineer / Systems Engineer / C++ Engineer / Python Engineer or similar.
• Strong systems engineering mindset and understanding of:
  • processes and concurrency;
  • memory ownership and data movement;
  • latency vs throughput trade-offs;
  • performance bottlenecks;
  • profiling and debugging;
  • failure modes of complex systems.
• Experience working with performance-sensitive or latency-sensitive systems.
• Experience with at least one of C++, Python, Go or a similar programming language.
• Python is used in the platform, but it does not need to be your primary language. Strong C++ / systems experience is equally relevant.
• Solid Linux fundamentals.

• Solid experience with Docker and containerised environments.

   

Nice-to-have

• CUDA, including IPC handles and stream synchronisation.
• C/C++ or Go.
• OpenCV.
• GStreamer, FFmpeg or RTSP.
• ZeroMQ.
• Shared memory / zero-copy architectures.
• FlatBuffers or other binary serialisation formats.
• Experience building or operating camera/video pipelines.

What we offer

• Competitive compensation.
• Benefits package.
• Strong engineering team.
• Opportunity to work on challenging real-time Computer Vision infrastructure.
• Meaningful industrial safety use case.
• Technical challenges and opportunities for professional growth.
