Tenexti

Tenexti is an emerging software development company based in Lviv. We specialize in creating innovative solutions, delivering high-quality results, and helping our clients turn their ideas into reality. With a passion for technology and a commitment to excellence, we strive to build lasting partnerships and drive meaningful impact through our work.

We are looking for an experienced Senior / Tech Lead to join our team.

🧑🏻‍💻How ideal candidate would look like for us:

• You are a good engineer. You don’t write code just to the point when it starts working. You go the extra mile to make your code elegant. You are passionate about technology and you take ownership of the things you implement. You have skills to design architecture that is simple, robust and easy to maintain
• You are a good team player. You treat people around you well and you like to work as part of a team
• You don’t need supervision, you are self-driven and you don’t need anyone to manage you. You can solve problems on your own
• You have the skills and experience in maintaining large, technically complex infrastructures. You are not afraid of it. You are senior enough to feel comfortable with this caliber of challenge.

💡What you will do:

• Play a key role in defining how particular feature should be implemented based on the architectural best practises
• Perform code review. Suggest better, cleaner, and simpler approaches
• Suggest technical improvements to the project: how to improve DevEx, how to improve system stability, and how to simplify the codebase, APIs, etc
• Implement complex features that span across multiple microservices
• Lead the team through technical challenges.

Team and Customer:

We are a team of engineers based in Lviv seeking a talented Senior Software Engineer / Tech Lead with experience in Node.js. You will be working with us for a US-based customer. All engineers are located in Lviv/Ivano-Frankivsk which means that all important architectural decisions are being made here locally, so you won’t have late calls with the team members from the US. This also means that all knowledge of the system is available on our side so you won’t be blocked by some knowledge holders that are located overseas.

Our customer is not backed by venture capital but by reliable source of business revenue. This means that we are self-funded and don’t experience pressure from the venture capital to cut roles in Ukraine due to “country risks”. You may be already aware that this is quite common lately.

The reason why we are hiring is due to business growth. We see that by leveraging technology and smart people we can empower the business to growth further.

Product:

At a high-level, the product we are working on is a service for ticket brokers that collects terabytes of information from the internet and processes it. Later on this data is processed and presented to clients so they can make a decision on which tickets to buy.

From the technical perspective this product is both interesting and challenging. It is very far from being a simple CRUD application. It is rather a set of different systems that are aimed at retrieving terabytes of data from the internet and process it efficiently and reliably.

Here are some technical details that might be interesting to know:

• To fulfill our business automation needs we run about 80~ chrome browsers 24/7
• We have constant load on the system of roughly 20-40 requests/second. Sometimes there are spikes that we need to tackle and stay resilient and responsive. While this number might not sound impressive, it is worth to note that we have to guarantee system reliability 24/7 and that some of the requests require browser interventions that leads to high resource allocations
• Our current infrastructure is backed by K8S cluster, that in total has 126 CPUs cores and 482GB of RAM as of the moment of writing.

🚀Our technology stack:

• Typescript, Node.js & Nest.js
• Prisma, MongoDB & Postgres, Redis
• Hasura & GraphQL
• Kubernetes
• CI built on top of ArgoCD and Github Actions
• React, react-query, Antd
• Java 21 & Spring Boot
• Opensearch for logs
• Prometheus & Grafana for metrics & traces. We use them heavily to build operational dashboards that show overall health of all pieces of the system.

Projects that we are actively working as of today, which you may be part of when you join:

• Reduce infrastructure cost from XX.XXX $ to X.XXX $ per month by migrating part of the system to kubernetes cluster built on top of dedicated servers at Hetzner
• Automating repetitive tasks that are being done by team of offshore contractors
• Increasing amount of integrations with ticket websites
• Brainstorming how we can leverage technology to empower business to produce more sales and revenue in general
• Maintaining integrations stability.

Why choose this project and team?

• Stable project that has been up for more than 8 years
• The entire RnD team is located in Lviv/Ukraine. All architectural decisions are being made here locally too. There are no knowledge holders oversees and no late calls
• Opportunity to work on a quite high load production system and have an impact on how it is designed and shaped.

Perks and Benefits:

🏋️‍♂️ Gym compensation

🍔 Partial compensation for transfer to office and food at office

🏝18 days of paid vacation, public holidays, and paid sick leave;

💻 Modern tech gear: MacBook based on silicon CPU (M1-M3) with 32 of RAM

🇬🇧 English lessons

⏱️ Flexible working hours and no time trackers

✈️ Possible trips to USA when the war ends. Before the war, we flew there twice and we loved it :)
