About lemon.markets

We enable anyone to be an investor. Our mission is to grow investing opportunities for all European customers and businesses. By empowering FinTechs, banks, and wealth managers to offer investment products, we help create financial well-being for their customers.

lemon.markets is a Brokerage-as-a-Service platform: simple digital access to capital markets through a single API. Our API-first infrastructure abstracts brokerage complexity with a well-documented API, a self-service customer operations portal, and a clear regulatory framework, so partners can launch customer-centric, compliant products in weeks, not months.

As part of the dwpbank group, we’re adding a layer of resources and expertise to benefit from, while continuing to operate as an independent fintech with our own team, product, and start-up identity under the dwpbank umbrella.

Your Mission:

As a DevSecOps Engineer, you will lead the design, guidance and automation of our cloud infrastructure security, with robust, secure and scalable solutions. You’ll develop proactively strategies and solutions to ensure security is at the heart of everything we do here at lemon.markets.

This means: you will have an important role in building our brokerage API offering that allows companies to easily embed brokerage services into their existing products.

Moreover, you will expand and improve our existing Trading API Product to become the leading trading API for developers.

About you:

If you don’t match every single point below, that’s completely okay, We’re looking for strong alignment with most of these areas, plus the curiosity and drive to learn the rest on the job.

• You have proven experience with AWS infrastructure and services and you know your way around AWS security fundamentals, such as VPC, Security Groups, Guard Duty, Control Tower or CloudTrail.

• You have experience securing Kubernetes, e.g., applying network policies, admission controls, OPA/policy-as-code, and service-mesh-aware security patterns.

• You understand the Software Development Lifecycle (SDLC) and its tooling (GitHub, CI/CD), and you know how to embed and operate security controls throughout the delivery lifecycle.

• You are well versed with IaC and Configuration management tools such as Terraform and Helm chart.

• You have hands-on experience with network and identity security, including firewalls/WAF, PKI/certificates, identity providers (IdP/SSO), and RBAC/least-privilege access controls.

• You have hands-on experience designing and operating a Vulnerability Management program end-to-end, covering SAST, DAST, SCA, container/image scanning, cloud/Kubernetes posture scanning, and runtime anomaly detection.

• It’s a plus to hold any Security Certifications such as: GSEC, CISSP, CCSP, CCSK, CISM, GCUX or SAST.

You will be successful if:

• Security is everything to you. We operate in a highly regulated environment and therefore having worked prior in a Fintech or Financial Service provider (Bank, Insurance or Brokerage) or within the Cyber Security industry would be preferred.

• You have a bias for action over discussion. To avoid getting stuck in discussion, you collect new feedback, try out a different approach or gather data with a proof of concept because you trust the process.

• You are ready and willing to take ownership of problems and act on them with no supervision and decisively.

• You have a collaborative mindset. Working together as a team and sharing knowledge comes natural to you. Long term - you consider becoming a team lead.

• You have no problem with learning new technologies on the go. You try to solve problems with more things than the ones you already know. We will always enable you with that, but your willingness has to come first.

How we take care of you:

• Compensation package: We offer you a competitive salary, based on your experience and the value-add you bring to lemon.markets.

• Flexible working hours: We trust people to choose when they work best and avoid a rigid 9 to 5 mindset. You decide on the rhythm that helps you do your best work, with only shared core hours from 12:00 to 16:00 to support collaboration.

• Hybrid work setup: You can work from anywhere in Germany within a hybrid model. At the same time, in-person collaboration is a key part of our culture.

• People & culture: You’ll feel our culture in the small things, like polaroids from our lemoneers’ first day, Friday food market strolls at Maybachufer, and our monthly new-joiner breakfast. But also in the bigger things: celebrating the onboarding of new partners, growing our teams, and owning a strong discussion culture.

• Perks & benefits: We choose benefits that add actual value. We sponsor a Deutschlandticket for employees on unlimited contracts, plus 50% off on Beatvest - our partner for financial education and investing.
