Software Engineer (Mid-level, Full-stack)

We're looking for a Mid-level Software Engineer to join the development team behind our in-house Transport Management System (TMS). The TMS is the operational backbone of Egala: dispatchers plan trucks, trailers and drivers on it, drivers use its mobile app on the road, and finance invoices customers and pays drivers from the data it holds. It is a mature, actively developed product – a Python/Django backend, a React frontend, a Flutter driver app and a long list of integrations with telematics, routing, ferry and accounting providers, shipped to production roughly every week.

This is a full-time, on-site role in our office in Żerniki near Poznań, with the option of occasional remote work when the need arises. We offer an employment contract, a B2B contract is open to negotiation if needed. You will own features end to end: from a ticket, through data model, API and UI, to tests, release notes. If you write solid Python and JavaScript, are comfortable reading a large codebase you did not write, and like the idea that a routing bug shows up as a truck on the wrong side of a border, we'd love to meet you.

Your responsibilities

• Build features end to end – take a ticket from the backlog (e.g. a new planning screen, an invoicing rule, a driver-app flow) through Django models and migrations, REST endpoints, React/MobX UI, tests and changelog.

• Integrate external systems – connect and maintain integrations with telematics providers, routing and map services, ferry and tunnel operators, tachograph data (DDD files), Microsoft 365 and accounting software over REST, SFTP and webhooks.

• Keep production healthy – pick up Sentry errors and user-reported incidents, reproduce them on a staging copy of production data, fix the root cause and prevent regressions.

• Care about performance – the system runs on a large PostgreSQL database; you will profile slow queries, design indexes, move work to Celery background tasks and keep screens fast.

• Write and maintain tests – Django unit tests for backend logic and Cypress end-to-end tests for user flows are part of every change, not an afterthought.

• Review and be reviewed – participate in merge-request reviews on GitLab, follow and improve team conventions and help keep the codebase coherent as it grows.

• Clarify before you build – ask questions when a ticket is unclear, occasionally directly with the dispatchers or finance staff who will use the feature; propose simpler solutions when the request can be met with less.

• Modernise responsibly – help with the gradual upgrades of the stack (Python, Django, React, TypeScript adoption) without stopping feature delivery.

• Communicate and stay Agile – priorities change; give short, regular updates on progress and blockers and re-plan when needed.

Our stack at a glance

• Backend – Python, Django, PostgreSQL, Celery with RabbitMQ and Redis, a WebSocket service (ASGI) for live updates, Gunicorn/gevent, Sentry and New Relic.

• Frontend – React, MobX and mobx-spine models, JavaScript, Semantic UI and styled-components, Leaflet maps.

• Mobile – TARA driver app in Flutter; several small native Android (Kotlin) tools such as the panic button and fleet-device managers.

• Integrations – many third-party systems: telematics, routing/toll calculation, ferries and Eurotunnel, tachograph downloads, Microsoft Graph, Exact Online, Firebase push, SFTP exchanges, AI-assisted order intake and receipt verification.

• Tooling – Docker Compose for the whole environment, GitLab CI with per-branch instant staging environments, Cypress (several hundred end-to-end specs).

• Scale – about 250k lines of backend code, 200k lines of frontend code, 100+ screens, releases roughly every week.

Our requirements

• 3–5 years of professional software development experience, with Python and Django used in a production system.

• Solid relational database skills – PostgreSQL preferred: data modelling, writing and reading non-trivial SQL, understanding query plans and indexes, safe schema migrations on live data.

• Practical frontend experience with React and a state-management library (MobX, Redux or similar), modern JavaScript.

• Experience integrating third-party APIs – REST and ideally SOAP; authentication flows (OAuth2, bearer tokens, API keys); retries and error handling for systems you do not control.

• Familiarity with asynchronous and scheduled work – Celery or an equivalent task queue; understanding what should and should not run inside a web request.

• Comfortable with Docker, Git and a CI pipeline (GitLab CI or similar) as daily tools; able to debug a failing pipeline on your own.

• A testing habit – unit tests for logic, end-to-end tests for flows; you know what to test and what not to.

• Ability to navigate and improve a large existing codebase – reading before writing, small focused merge requests, no unnecessary rewrites.

• Good English (B2/C1) – the codebase, tickets, reviews and part of the team communication are in English; Polish is used day to day in the office.

• Clear communication, verbal and written – you can explain a technical trade-off to a non-technical colleague and keep status updates short, regular and honest.

• Ownership and a proactive mindset – you notice problems before users report them and propose fixes rather than waiting for a ticket.

Nice to have

• Experience in transport, logistics or fleet-management software (TMS, telematics, route planning, tachograph/driving-time regulations).

• Maps and geo work – Leaflet or similar, routing/geocoding APIs (PTV, Google, HERE), polylines, time zones, distance and toll calculation.

• Performance and observability tooling – Sentry, New Relic, PostgreSQL EXPLAIN, Celery monitoring (Flower).

• Experience upgrading long-lived Django/React applications across major versions.

• Dutch language, or experience working with a Dutch organisation.

• Degree in Computer Science or a related field.
