Pertemps ERP is actively recruiting a Senior Go Backend Developer for a hybrid role based in Hamburg, offering a salary of up to €90,000. The position sits inside a fast-growing international technology company operating a large-scale data platform that serves hundreds of millions of users globally. Competition for roles like this is fierce, and understanding exactly what the hiring team wants gives you a real advantage.
What Pertemps ERP Is Looking For
The company behind this role runs infrastructure at enormous scale. Every day, their systems process and analyse millions of real-time events. That context shapes everything they look for in a candidate.
They are not searching for someone who has simply written Go code. They need an engineer who has built and maintained high-performance services under real production pressure. Experience means little without evidence of scale.
The ideal candidate brings these qualities to the table:
- Deep comfort working in distributed, microservices-based environments
- A strong instinct for performance bottlenecks and database optimisation
- Confidence designing systems that process millions of concurrent events
- The ability to collaborate clearly in an English-speaking international team
The Core Skills You Need to Demonstrate
The job posting lays out its technical requirements with unusual clarity. Meeting the minimum bar is not enough. You need to show mastery, not familiarity.
Go Development Experience
Pertemps ERP requires at least three years of commercial Go development. Personal projects or short freelance work are unlikely to satisfy this requirement. Employers at this level want production-grade Go work on real systems.
Your Go experience should cover concurrency patterns, efficient memory management, and building reliable APIs. Knowing the language syntax is the starting point, not the finish line.
Distributed Systems and Kafka
Kafka and event-driven architecture sit at the heart of this role. The platform processes millions of events daily, and Kafka is the engine that makes that possible. Candidates without hands-on Kafka experience will struggle to compete.
Bring examples of Kafka implementations you have designed or maintained. Topics, consumer groups, partition strategies, and fault tolerance are all fair game in interviews. Knowing the theory alone will not be enough.
Database Optimisation
The role calls for solid skills in MySQL, Druid, or similar database technologies. Optimising queries across large-scale datasets is a daily reality here. You should be ready to discuss indexing strategies, query planning, and how you have improved performance in previous roles.
Druid is a specialised analytical database used for real-time data ingestion. If you have Druid experience, highlight it prominently. It is a rarer skill that could set you apart from other applicants.
Cloud-Native and Microservices Infrastructure
The engineering team builds on cloud-native, microservices-based infrastructure. Experience with container orchestration, service meshes, and cloud deployment patterns is directly relevant. Candidates who understand how microservices fail, scale, and recover will impress interviewers more than those who only know how to build them.
The Minimum Experience Requirements
Pertemps ERP sets a clear floor for applicants. You need:
- 5+ years of total software development experience
- 3+ years of commercial Go development specifically
- Proven experience operating services at significant scale
- Strong distributed systems background with microservices knowledge
Candidates who fall short on any of these points are unlikely to progress past the initial screening stage. Be honest with yourself before applying.
Understanding the Hiring Process
Pertemps ERP operates as a recruitment partner for this role. That means you are applying through a specialist technology recruiter who will screen you before presenting your profile to the end employer. This adds one layer to the process but also gives you access to insider information about what the company values.
Initial Recruiter Screening
Your first conversation will likely be with a Pertemps ERP recruiter. They will assess your technical background, salary expectations, and availability. Be direct and specific about your Go experience and the scale of systems you have worked on. Vague answers at this stage result in early elimination.
Ask the recruiter about the company culture, team structure, and what the interviewers prioritise. Recruiters have this information and sharing it is part of their job.
Technical Assessment
Most senior backend roles at this level include a technical test or take-home assignment. Expect questions or tasks involving Go service design, distributed system architecture, or performance optimisation scenarios. Kafka-related design problems are particularly common in this space.
Read all instructions carefully before starting. Time management during technical assessments is a skill in itself.
Technical Interview Rounds
Engineering interviews will go deep on your past work. Expect questions like "Tell me about a system you built that had to scale under unexpected load" or "How have you handled message ordering guarantees in Kafka?" These are not hypothetical. Interviewers want real examples with real outcomes.
Prepare three to five concrete stories from your career that demonstrate scale, problem-solving, and technical depth. Practice telling them clearly and concisely.
Cultural and Team Fit Interview
The team is international and works entirely in English. Expect at least one conversation focused on collaboration style, communication, and how you handle disagreement or ambiguity. This is not a formality. Cultural fit in globally distributed teams is taken seriously at companies of this type.
Interview Tips That Actually Matter
Generic interview advice rarely helps for senior technical roles. These tips are specific to this type of position and company.
- Lead with scale: Always frame your experience in terms of volume, throughput, and impact. Numbers matter more than descriptions.
- Know your failure stories: Senior engineers are expected to have made mistakes and learned from them. Hiding failures looks worse than owning them.
- Prepare Kafka architecture diagrams: Being able to sketch out a Kafka-based event pipeline on the spot demonstrates real fluency.
- Ask smart questions: Questions about their current architecture challenges show genuine interest and technical maturity.
- Do not oversell unfamiliar tools: If you have limited Druid experience, say so clearly while emphasising your ability to learn quickly with evidence.
How to Stand Out From Other Applicants
For a role serving hundreds of millions of users, the bar is genuinely high. Standing out requires more than meeting the requirements on paper.
Write a tailored cover letter or application message that references the specific technologies named in the posting. Mention Kafka, Go, and distributed systems directly. Generic applications get ignored at senior level.
If you have public GitHub repositories with Go code, link them in your application. Open source contributions to Go tooling or Kafka-related projects carry particular weight here. Showing your work removes doubt.
Relocation support is available for candidates moving to Hamburg. If you are applying from outside Germany, acknowledge this in your application and confirm your willingness to relocate. Removing logistical uncertainty makes hiring managers more comfortable moving forward with your profile.
The Compensation and What It Signals
The role offers a salary of up to €90,000, depending on experience. This is a competitive figure for Hamburg's technology market, particularly for a hybrid role. It signals that the company values senior-level expertise and is willing to pay for it.
Candidates with strong Kafka experience, proven scale, and a track record of building reliable Go services are positioned to negotiate toward the top of that range. Go into salary discussions with data about market rates and confidence in your value.
