Job description

Customer Support Engineer – Hybrid – Gothenburg, Sweden

We seek a Customer Support Engineer to join our team at Microdeb in Gothenburg, Sweden!

About the role

We're looking for a Support Engineer to join our team in Gothenburg. This is not a ticket‑shuffling role. You'll be the person customers rely on when something breaks, when a query won't return, when a deployment misbehaves — and you'll have the technical depth to actually fix it, not just elevate it. You'll work across SQL databases, light development tasks, and customer‑facing troubleshooting, with modern AI tools as a core part of how you work.

What you'll do

Own customer issues end‑to‑end, from first contact through root cause and resolution. Diagnose and resolve database problems: query performance, indexing, locking, data integrity, backup and recovery. Write and review SQL — from quick investigative queries to stored procedures and schema changes. Read, debug, and occasionally patch application code to identify the source of issues. Reproduce bugs in test environments, file detailed reports for engineering, and follow through. Build internal tools, scripts, and automations that reduce repeat work and speed up diagnosis. Use AI tools (Claude, Copilot, internal LLM workflows) to accelerate investigation, draft responses, generate queries, and analyse logs. Improve documentation and runbooks so the next person resolves the same issue faster.

What we're looking for

Solid hands‑on experience as a DBA or in a database‑heavy support or engineering role. Strong SQL skills — you can write complex queries, read execution plans, and tune performance without reaching for a tutorial. Working knowledge of at least one general‑purpose language (Python, C#, Java, JavaScript, or similar) — enough to read a codebase, debug, and write small fixes or tools. Fluency with AI‑assisted workflows: you already use LLMs daily for coding, investigation, and writing, and you have opinions about where they help and where they don't. A bias for action: you'd rather dig in and reproduce the issue than wait for more information. Clear written communication in English — you can explain a technical problem to a non‑technical customer and to a senior engineer in the same day. Based in or willing to relocate to Gothenburg.

Nice to have

Experience with cloud databases (Azure SQL, AWS RDS, Snowflake, or similar). Familiarity with observability tools (Datadog, Grafana, OpenTelemetry). Exposure to CI/CD and infrastructure‑as‑code. Swedish language skills (not required — our working language is English).

Why this role

You'll see more of the product, the codebase, and real customer problems than almost any other role. Support engineers here move into platform, backend, or SRE roles when they want to. We invest in AI tooling and expect everyone to use it well — not as a gimmick, but as leverage.

You'll be based anywhere in Sweden, working in a hybrid work model from our office in Gothenburg!

About You

Required

• Bachelor's degree in Computer Science, Software Engineering, Information Systems, or equivalent practical experience
• 2+ years in a technical support, DBA, or software engineering role with direct customer or stakeholder contact
• Demonstrable SQL expertise: joins, window functions, CTEs, indexing strategy, query plan analysis, and performance tuning on a major RDBMS (SQL Server, PostgreSQL, MySQL, or Oracle)
• Hands‑on experience administering databases: backups and restores, user and permission management, monitoring, and incident response
• Proficiency in at least one programming language (Python, C#, Java, JavaScript/TypeScript, or similar) sufficient to debug application code and write small utilities
• Working knowledge of Git and standard development workflows (branches, pull requests, code review)
• Experience using AI coding assistants and LLMs as part of a daily workflow — writing prompts that produce useful output, knowing when to verify, knowing when not to use them.
• Strong written and spoken English. Eligible to work in Sweden

Preferred

• Experience with cloud‑hosted databases (Azure SQL, AWS RDS or Aurora, Google Cloud SQL, Snowflake, BigQuery)
• Familiarity with Linux command line, shell scripting, and basic networking (DNS, TLS, HTTP, firewalls)
• Exposure to containerization (Docker) and orchestration (Kubernetes). Experience with logging and observability stacks (ELK, Datadog, Grafana, Splunk, OpenTelemetry)
• Knowledge of REST APIs and how to debug them (Postman, curl, browser dev tools)
• Familiarity with CI/CD pipelines (GitHub Actions, Azure DevOps, GitLab CI)
• Prior experience in a SaaS or B2B product environment
• Swedish language skills

Personal attributes

• Curious by default — you want to know why something broke, not just how to make the symptom go away
• Comfortable holding two threads at once: the customer who needs an answer now, and the underlying defect that needs a proper fix
• Disciplined writer — your tickets, postmortems, and documentation make life easier for the next person. Direct and honest in communication, internally and with customers
• Treats AI tools as leverage, not as a crutch — verifies output, understands the code that gets generated, and improves prompts over time

About the team

• You join our Support Engineering team in Gothenburg — a technical group that works at the intersection of engineering and customer success
• We're the people the rest of the company turns to when something genuinely hard breaks, and we work closely with Engineering, Product, and Customer Success to make sure issues get resolved properly, not just closed
• How we work: we treat every incident as a chance to learn, document thoroughly so problems don't cost us twice, pair on hard tickets, and push fixes back into the product rather than working around them
• We use AI tools heavily as part of our daily workflow and share what works across the team
• You can expect real ownership of problems from first report to root cause, direct access to the engineers who built the system, and room to grow into adjacent technical roles over time
• We're not a call centre, and we're not a feature factory — we're a team that takes pride in solving real problems well
