Product Engineer - Special Projects (d/f/m)

Short Facts

We’re a fast-growing Special Projects team at Entrix working independently on a new platform. We’re building a product that connects to distributed energy systems and enables real-time asset management and market participation. We ship quickly, operate what we build, and care deeply about engineering fundamentals: scalability, security, observability, and maintainability.

• Location: Munich, Germany
• Working Mode: Office-first setup
• Type: Full-time, permanent
• Salary: €90,000 – €120,000 (depending on experience and leveling)
• Language: English (C1+)

Your Responsibilities

In this role you will:

• Build and maintain a scalable, secure, high-performance product, owning features end-to-end: data modeling → APIs → UI → testing → production rollout.
• Drive engineering excellence with strong code quality, reviews, and pragmatic architecture decisions.
• Implement robust system observability to track performance and key operational metrics.
• Improve developer experience so the team can ship high-quality features faster (tooling, patterns, docs, tests).
• Collaborate cross-functionally across the Entrix ecosystem to shape the platform direction.

Your Profile

What great looks like in this role:

• You ship meaningful product increments at a high velocity without process overheads.
• You leave parts of the system cleaner than you found them (tests, interfaces, docs).
• You make trade-offs explicit: latency vs. cost, speed vs. safety, developer experience vs. complexity.
• You build systems that are extremely reliable and maintain consistent performance.
• You’re highly customer focused and actively seek opportunities to generate value for our customers.

You will be a great fit if...

• 3+ years of professional software engineering experience in a fast-paced environment.
• Strong Python (FastAPI) and strong TypeScript/React (Next.js) proficiency.
• Hands-on experience deploying and operating production systems on AWS (ECS, Lambda, RDS, DynamoDB, S3, IAM) using Infrastructure-as-code (AWS CDK / Terraform / Pulumi).
• Strong API design sense (REST, OpenAPI), and comfort with CI/CD + Docker.
• Ownership mindset: you drive from “idea” to “shipped” and care about what happens after deploy.
• Great communication skills to effectively bring across complex ideas and concepts with an ability to work on solutions individually.

Nice-to-haves:

• Experience deploying AI-driven automations to speed up shipping.
• Experience with real-time systems (streaming using AWS Kinesis/Kafka) built on top of time-series data (InfluxDB/TimescaleDB).
• Interest in systems that touch real-world hardware.

At Entrix, we are committed to diversity - of backgrounds and experiences. You don’t need 100% of the preferred qualifications to add incredible value to our team. If you’re passionate about what you could accomplish here, we’d love to hear from you.

Your Benefits

• Competitive Compensation Package: Including salary, benefits and options.
• Professional Development: Annual development budget of 3,000 € for coachings, trainings, books, etc.
• Health & Sport Subsidy: Company subsidised sports facilities membership.
• Public Transportation Subsidy: Monthly subsidy to your public transport ticket.
• Lunch/Dinner Allowance Vouchers: Allowance for meals on working days as digital meal vouchers.
• Work Equipment: Mac Book or Windows Laptop and ergonomic workplace.
• Regular Team Events: Knowledge Sessions, Afterwork, Sports, Offsites, Halloween, Pride Month, etc.
• Exclusive merch you’ll love.

A Short Note from Your Future Lead

Tech Lead - Special Projects

Faheem Zunjani

Hi there!

I’m Faheem, and I lead the engineering team in Entrix’s Special Projects division, where we’re building a new platform from scratch inside the Entrix ecosystem. My background spans applied AI and production systems — across e-commerce at Amazon and autonomous driving at Cruise and BMW — which taught me what it takes to build software that stays reliable when the stakes are real.

Before Entrix, I co-founded cleanbrix (now Building Enerlytics), using computer vision to improve building energy efficiency — a zero-to-one journey that shaped how I work: ship early, work with customers to learn fast, and keep a high bar in production.

Energy is transforming quickly, and we’re at the forefront of it — building products that turn flexibility into real value. We’re a small team that works hard and combines fast shipping with strong engineering fundamentals — security, observability, and end-to-end ownership — so we can build systems our customers can rely on.

If you enjoy building end-to-end and want your work to matter, I’d love to talk.

Best, Faheem
