Backend Tech Lead

Job description

Backend Tech Lead – Libra

Location: Poland
Company: Navro - Pioneering the Future of Payments

Not Your Typical Backend Tech Lead Role

This isn’t just another leadership position.

No legacy systems.

No corporate red tape.

No coasting.

This is about building something from the ground up.

Fast.

We’re Navro, a rapidly scaling B2B payments startup, and we’re looking for an enthusiastic, driven Backend Tech Lead to join our Engineering Tribe.

This is your chance to shape our technical direction, set the vision, and make decisions that impact the entire business.

You won’t have layers of approval slowing you down.

You’ll have the freedom to make real, impactful decisions from day one.

This isn’t a passenger role.

We’re bringing you in for your expertise, your technical leadership, and your relentless drive.

At Navro, we value diversity and are committed to creating an environment where everyone feels supported and empowered to contribute their unique perspectives.

We’re not just offering a job – we’re offering an adventure alongside a great team.

Who We Are 

We are transforming payments for global platforms and e-commerce businesses.

As the world’s first payments curation platform, we simplify cross-border transactions by uniting best-in-class infrastructure into a seamless ecosystem, enabling businesses to scale and operate effortlessly across borders.

Cross-border workforce payments are slow, expensive, and outdated.

We can’t be.

Businesses rely on us to pay their people accurately and on time - contractors, freelancers, and employees across the globe.

When we say we’ll deliver, failure isn’t an option.

If we don’t do what we said we would, people don’t get paid - not just a transaction delayed, but real workers left without wages.

That means a developer in Argentina missing their paycheck, a freelancer in the Philippines unable to pay rent, or a contractor in Poland unable to get to work.

No excuses.

No passengers.

No tolerance for politics or mediocrity.

Requirements

What This Role Demands:

⚡ You Own It – You’re accountable for every technical decision and every system outcome.

If it breaks, you fix it.

⚡ You Lead from the Front – You mentor engineers, contribute to the codebase, and set high standards for quality, performance, and reliability.

⚡ You Challenge & Improve – You question assumptions, push for smarter solutions, and make us better every day.

⚡ You’re Hands-On – From designing complex financial systems to solving gnarly production issues, you don’t shy away from the details.

⚡ You Thrive in Chaos – Startups are messy.

Priorities shift.

Requirements evolve.

You bring clarity without slowing down.

⚡ You Handle the Pressure – High stakes, fast pace, and critical systems.

You keep calm and deliver.

⚡ You’re Here for the Journey – This is career-defining.

It’s challenging, rewarding, and not for the faint-hearted.

What You’ll Be Doing:

• Deploy and develop backend systems powering the Libra Tribe, focusing on banking integrations, treasury platforms, and FX operations.
• Drive the design of solutions that meet accounting, compliance, and financial controls requirements.
• Lead cloud-native development efforts, deploying systems on Kubernetes and AWS, with flexibility for multi-cloud strategies.
• Build and support systems for banking relationships, payment processing, reconciliation, liquidity management, and FX transactions.
• Provide mentorship and guidance to engineers, fostering collaboration across the team.
• Collaborate with product managers and other tribes to ensure technical alignment with business priorities.
• Champion high standards for code quality, scalability, and resilience, applying the 12-Factor App methodology.

What We’re Looking For:

⚡ Tech Expert – Strong experience designing and deploying API-first, cloud-native backend systems (payments/fintech experience ideal).

 ⚡ Java Pro – Highly proficient in Java, Spring Boot, Spring Cloud, and reactive frameworks like WebFlux/Project Reactor.

 ⚡ MongoDB Expert – Highly proficient with MongoDB, including deep knowledge of the Aggregation Framework, indexing strategies, and performance tuning.

Experienced in working on scalable, highly available clusters using sharding and replica sets, particularly within MongoDB Atlas.

 ⚡ FinTech Fluent – Hands-on knowledge of banking systems, treasury operations, FX management, payment flows, reconciliation, and ledgers.

 ⚡ Cloud Native – Deep experience with Kubernetes, Spinnaker, AWS, and ideally multi-cloud strategies.

 ⚡ Compliance-Minded – Understanding of financial compliance and accounting standards, with experience building audit-ready systems.

 ⚡ Mentor & Leader – Passionate about developing engineers and leading by example.

 ⚡ Collaborator – Comfortable working with cross-functional stakeholders.

 ⚡ Startup DNA – Resilient, adaptable, and motivated by building things that matter.

You may not possess every single required skill listed, and that's perfectly fine.

If you have most of them, along with grit, passion, a desire to learn quickly, and the willingness to get stuck in, we encourage you to apply.
