So, what's the role all about?

We’re seeking someone who is technically strong, thinks in context, looks for solutions instead of excuses, and is enthusiastic about AI and able to use it to work more effectively. 

How will you make an impact?

Our product is part of a comprehensive SaaS solution for contact centers. 
We develop channels / adapters that integrate with third-party platforms such as Facebook, WhatsApp, SMS, etc., and synchronize communication between these services and the rest of our product. 

We manage over 30 integrations across 17 regions worldwide, and our product is used daily by hundreds to thousands of large multinational companies. Reliability, scalability, and the ability to respond quickly are critical for us. Approximately 200 million requests pass through our integrations every day. 

We do not build a monolith. Each adapter has its own repository, which eventually led us to adopt a monorepo approach. Our codebase is intentionally not overly complex, which helps us maintain very low defect rates across teams. We regularly monitor the health of our integrations via Kibana dashboards and aim to fix most issues immediately (the rest are handled based on priority). 

Our product communicates with services such as AWS Kinesis, AWS SQS, and AWS Lambda. We don’t expect you to be an expert in every one of them, but we do expect you to understand their fundamental principles.

• You can clearly articulate technical arguments and collaboratively find the best way to design a feature 

• You are a senior software engineer 

• You are enthusiastic about AI and enjoy being more productive thanks to it 

• You follow Domain‑Driven Design (DDD) and SOLID principles in software development 
• You must be fluent in English, Czech 

Technologies We Use

• Symfony (Console), Doctrine (ORM), Nette (DI) 

• AWS (ECR, ECS, Aurora RDS, Kinesis, SQS, ElastiCache / Valkey) 

• GitHub Actions, Jenkins 

• Claude Code 

• Ansible / Terraform, Docker

Koho hledáme - Lead Software Engineer: 
Hledáme tech. leada do našeho Channels týmu. Hledáme člověka, který je technicky zběhlý, přemýšlí v souvislostech, hledá řešení místo výmluv a je nadšený do AI a dokáže díky tomu fungovat efektivněji. 

Jaké bys měl mít zkušenosti/vlastnosti: 

• Dokážeš rozumě argumentovat a hledat řešení jak danou featuru navrhnout co nejlépe 

• Jsi seniorní vývojář 

• Jsi nadšený do AI a baví Tě být díky tomu efektivnější 

• Při vývoji SW se řídíš Domain‑Driven Design a SOLID principy 

• Musíš umět anglicky 

Co děláme: 
Náš produkt je součástí komplexního SaaS řešení pro kontaktní centra. Vyvíjíme channels / adaptéry, které se napojují na třetí strany jako Facebook, WhatsApp, SMS, atd. a synchronizují komunikaci mezi těmito službami a zbytkem produktu. 

Spravujeme více než 30 integrací v 17 regionech po celém světě a náš produkt denně využívají stovky až tisíce velkých nadnárodních společností. Spolehlivost, škálovatelnost a schopnost rychle reagovat jsou pro nás klíčové.  

Nevyvíjíme monolit. Každý adaptér má vlastní repozitář, což nás postupně dovedlo k použití monorepa. Naše codebase není z principu složitá a i díky tomu máme napříč českými týmy velmi nízkou chybovost. Pravidelně sledujeme stav naších integrací v Kibana dashboardu a snažíme se většinu problému opravovat hned (zbytek záleží na prioritě). 

Produkt komunikuje se službami jako AWS Kinesis, AWS SQS nebo AWS Lambda -nepotřebujeme z tebe specialistu na každou z nich, ale očekáváme, že budeš rozumět jejich principům.

#LI-Hybrid

We are ShipMonk, and we provide logistics services in order fulfillment. Our main business is in the USA, but our modern platform is built by the Product Development team in Prague.

Here at ShipMonk, we process up to 100,000 orders per day in our peak season. Our book of business has more than 1,500 clients which are small and medium e-shops, mostly based in the US. We offer the ShipMonk platform as the solution for the whole process.  It covers everything from stocking the items to shipping the ready packages to all corners of the world!

We are looking for a skilled PHP Developer to join ShipMonk! This is an exciting opportunity to join our Product Development Team located in Prague. Please take a look at the details below.

Tech Stack:

• PHP 8.5
• Symfony 7
• Docker
• Kubernetes
• Doctrine ORM 3
• RabbitMQ
• MySQL 8
• GraphQL
• Elasticsearch

Our teams:

• Warehouse: optimization and automation of warehouse processes
• Internals: refactoring, tech-debt reduction, and legacy code removal
• Customer features: development of the functions of the existing web environment
• Frontend: TypeScript clients in React, E2E
• DataScience: AI, DWH, data-governance, prediction, and optimization, business intelligence
• QA: acceptance-criteria testing
• DevOps: Infrastructure, Kubernetes, CI/CD management and Cloud platform management
• Technical Product Managers: Asana & project management

What does it look like and what we are proud of:

• The main backend application provides a REST-like API for several types of clients (web, autonomous robots, iOS picker devices, microcomputer packers, automatic conveyors and more).
• We have the rest of the applications and clients in monorepo for easier CI checks, code sharing, etc.
• We have all services completely dockerized for local development. We deploy builds to a hosted Kubernetes cluster in AWS with a single click on the Argo CD several times a day.
• Each MR can be deployed on a separate cluster for one-button testing in the CI, so we don't argue about a test environment.
• We have set up a lot of checks in GitLab CI (PHPStan, PHP_CodeSniffer, PHPUnit, lint, editorconfig-check, migration check, security scans, renovate-bot).
• In addition to static analysis, we also do a two-round review and the operation is also verified by the QA team and E2E cypress tests.
• We have more than 15 000 database integration tests with the thoughtful creation of independent datasets for each test, ie no shared data that breaks forever.
• We directly automate the agreed coding-rules, so we have already written dozens of our own phpstan rules and coding-standard sniffs.
• We think about concurrence and design the application to withstand race conditions, which is not exceptional in a warehouse environment.
• The application is supported by DataDog, Sentry, and Opsgenie.
• Our database has grown to terabyte size, so even the optimization of SQL queries is becoming the daily bread of all of us.
• We deal with HA, failover, and autoscaling, almost no service runs for us only once.
• Having experienced colleagues is our huge advantage.
• We automatically generate documentation of all our REST-like endpoints.
• We open-source some of our best tools and contribute back to the OS community.
• We utilize code coverage.

If you like what we do, and our "story" got you interested, we look forward to seeing your resume, profile, story, or anything else you might have! There are no limits to creativity. Our Recruiter will get back to you as soon as possible. We look forward to hearing from you!
