About the Role 

We’re looking for a Python Developer who wants to take real ownership of what they build - from understanding the problem and shaping the solution to delivering a reliable result in production.

Depending on the project, you may be building a new product from the ground up, extending an established platform, solving complex technical problems, or improving systems that already serve real users. We don’t expect engineers to simply execute predefined tasks. We expect them to understand the context, make sound technical decisions, communicate openly with clients and teammates, and take responsibility for the outcome.

You’ll use AI/LLM tools extensively where they make you more effective - for implementation, analysis, testing, debugging, research, and everyday development workflows — while applying your own judgment to what gets designed, reviewed, and shipped.

We value ownership, product thinking, pragmatism, curiosity, and clear communication. If you care not only about how something is implemented, but also why it is being built and whether it actually solves the problem, you’ll fit well here.

Required Hard Skills

1. Software development experience with:

• Python and Django.
• Other Python frameworks (e.g., Flask).
• PostgreSQL, MySQL.
• Celery, Redis, ElasticSearch.
• Cloud providers, DevOps, CI/CD.
• Unit, integration, E2E tests.

2. Knowledge of REST and experience working with REST APIs.

3. Experience with JS, HTML, CSS (Usually 0-20% of activity).

4. Fluent in Claude, Codex, or similar products. Knows how to set up local agents and their limitations.

Required Soft Skills

• Ownership and accountability. Takes responsibility for their work and follows through on commitments.
• Strong communication and collaboration skills. Communicates clearly and works effectively with teammates and external stakeholders.
•  Solution-oriented mindset. Focuses on finding practical solutions rather than getting stuck in problems or unnecessary details.
• Product mindset. Understands the purpose behind the work and cares about the impact on the product and its users.
• Pragmatic decision-making. Knows how to balance quality, speed, and complexity, and when a solution is good enough.
• Adaptability and willingness to learn. Comfortable with changing projects, technologies, and requirements, and enjoys learning new things.

Key Responsibilities

• Depending on the project, you may be building products from scratch, working as part of existing development teams, modernizing or rewriting existing solutions.
• Solve technical challenges - all our projects are different, and you’ll never be bored with the same tasks every day, so your acquisitive mind will have great challenges regularly.
• Take care of quality (code, test, business features, documentation) - everyone enjoys working with clean, readable code, so it is important to keep it such.
• Participate in code reviews - usually, it is cross-reviews in the team or reviews by a senior person.
• Communicate with internal and external teams - we’re in touch with great minds - inventive clients, and supportive colleagues!
• Follow and actively apply our AI-assisted development approach in everyday engineering work, using AI across code generation, refactoring, debugging, documentation, and technical research.

Who this position is not for
This role is not for someone who prefers routine tasks, works only from predefined requirements, or avoids taking ownership of technical decisions. It may also not be the right fit if you’re not interested in learning new technologies, collaborating closely with others, or exploring how AI can improve the way you build software. 

We are looking for people who are motivated to learn, take ownership, and grow together with us.

Backend Developer (Node.js / TypeScript): Android Infrastructure, Reverse Engineering, High-Load

We are looking for a strong Backend Developer for a high-load project connected with Android infrastructure, reverse engineering, network traffic analysis, and processing large amounts of data.

The main backend is built on Node.js, so strong knowledge of JavaScript and TypeScript is required.

Please note: this is not a web development position. You will work with software — native Android applications, their internals, and their network communication — not with websites or browser-based web applications. Candidates without hands-on experience working with software at this level will not be considered.

Responsibilities

• Develop and maintain backend services using Node.js / TypeScript.
• Work with high-load and distributed systems.
• Design systems for storing and processing large amounts of data.
• Work with PostgreSQL, ClickHouse, and Redis.
• Optimize database queries, indexes, and data structure.
• Work with replication, sharding, partitioning, distributed data, high availability, and fault tolerance.
• Work with Kubernetes infrastructure.
• Find and fix performance problems in backend, databases, and infrastructure.
• Analyze network traffic and the communication of native Android applications.
• Work with traffic sniffing and proxy tools.
• Understand how mobile applications communicate with backend services and APIs.
• Analyze requests, responses, headers, payloads, tokens, and sessions.
• Work with existing code and systems with limited documentation.
• Find technical problems and propose solutions independently.
• Work with distributed workers, services, and nodes.

Required Skills

Software / Reverse Engineering / Network Analysis (mandatory)

• Hands-on experience with Android reverse engineering (not just theoretical understanding).
• Practical experience intercepting and analyzing traffic of native applications (mitmproxy, Burp Suite, Charles, Frida, or similar).
• Understanding of Android architecture.
• Good understanding of HTTP / HTTPS.
• Understanding of TLS, including certificate pinning and how it affects traffic analysis.
• Experience with proxy-based traffic analysis.
• Understanding of authentication, sessions, cookies, and tokens at the application level.

Backend

• Strong experience with Node.js.
• Strong knowledge of JavaScript and TypeScript.
• Good understanding of async programming.
• Understanding of the Node.js event loop.
• Experience with REST API and WebSocket.
• Experience with high-load backend systems.

Databases

• Strong experience with PostgreSQL.
• Strong experience with ClickHouse.
• Strong experience with Redis.
• Good understanding of indexes, query optimization, query plans, replication, sharding, partitioning, distributed databases, data consistency, and high availability.

Experience with large databases and high traffic is very important.

Infrastructure

• Kubernetes.
• Docker.
• Linux.
• Experience with cluster systems.
• Understanding of networking, load balancing, and horizontal scaling.
• Ability to find CPU, RAM, disk, and network bottlenecks.
• Experience with logs and monitoring.

Important: read before applying

This role is about software, not web applications.

Our backend does not serve a website or a typical web product. It supports infrastructure built around native Android applications: we analyze how the apps work, how they communicate over the network, and we process the data at scale.

This is a strict requirement:

• You must have real, practical experience working with software (native/mobile applications): analyzing app behavior, intercepting and inspecting traffic, understanding protocols, sessions, and tokens at the application level.
• Experience limited to web development (websites, admin panels, CRUD APIs for web frontends, e-commerce, CMS) is not sufficient, regardless of seniority.
• Applications without this experience are not reviewed.

The candidate should understand the full system:

application → network → backend → databases → infrastructure

The developer should be able to work independently, research technical problems, understand existing systems, and find solutions even when documentation is limited.

Level

Strong Middle / Senior Backend Developer

Will be a plus

• Large-scale data processing.
• Complex or undocumented APIs.
• Systems with many workers and nodes.
• Experience with Frida, native libraries (JNI / .so), or protocol analysis beyond HTTP (protobuf, gRPC, custom binary protocols).

Your responsibilities
Development

• Own the electronics architecture of the device: processor platform, power supply, sensing, actuation, display, connectivity.
• Circuit design and PCB layout, from concept through to release
• Analogue measurement chains for pressure, temperature and flow sensing — low noise, low drift, calibratable.
• Drive electronics for pumps, valves, heating and cooling elements, including the power stages.
• Build, bring-up and characterisation of prototypes.
• Safety and evidence.
• Electrical safety concept under IEC 60601-1: insulation coordination, creepage and clearance distances, protective earth, single-fault safety.
• EMC-compliant design under IEC 60601-1-2, pre-compliance measurements and support through certification testing.
• Design of an independent hardware protection layer: watchdog, interlocks, pressure and temperature limiting.
• Contribute to risk management under ISO 14971; derive and verify hardware risk control measures.

• Design verification: test planning, execution and documentation as part of the technical file

   

Production readiness

• Design for reprocessing: connectors, sealing concepts and resistance to cleaning and disinfecting agents across the specified service life.
• Design for manufacturing and test: test strategy, production programming, test fixtures.
• Component qualification, second sources, long-term availability and obsolescence management.
• Work with EMS providers, prototype builds and production ramp-up
   

Collaboration

• Work closely with embedded software: platform decisions are made together, not one after the other.
• Interface with mechanical engineering, systems engineering, regulatory affairs and manufacturin.

Required

• Several years in electronics development for complex embedded devices, from schematic to finished layout (7+ as a guide).
• IEC 60601-1 or an equivalent product safety standard (e.g. IEC 61010) — insulation concepts, creepage and clearance, single fault analysis are routine for you, not new ground.
• Solid practice in analogue measurement: sensor front-ends, ADC interfacing, noise, offset and drift, calibration concepts.
• EMC-compliant design in practice — including the experience of analysing and fixing a failed EMC test.
• Confident with a professional EDA tool (Altium, KiCad, Cadence or comparable).
• Lab measurement skills: oscilloscope, spectrum analyser, network analyser, thermography
• Fluent German and English
   

Nice to have

• Medical devices and the associated documentation (design history file, design verification).
• Further parts of the 60601 series, in particular -1-2 (EMC), -1-6 (usability) and -1-8 (alarm systems)
• Mains-side power electronics, switch-mode supplies, isolation barriers, motor drive.
• Signal and power integrity on fast interfaces (DDR, LVDS, Ethernet).
• Modern 32-bit microcontroller platforms and the circuitry around them.
• Thermal design and simulation.
• Experience setting technical direction across distributed or partner teams.

What we explicitly do not require

• Prior experience in our application field. We will teach you the domain.
• Every line of the list above. If three quarters fit and you want to learn the rest, apply.
