Support Engineer - Voice

Are you the kind of engineer who thrives on the puzzle of a live production issue, digging past the surface symptoms to expose the true root cause?

At boost.ai, we are currently scaling up our Voice team. 2026 is the year of Voice!

With a steady 15-20% YoY growth rate at boost.ai, we are the go-to Conversational AI provider for regulated sectors such as finance, the public sector, insurance, and telecom, and we are expanding into many more industries, including healthcare.

We are not just another "wrapper" that popped up overnight.

We are a bona fide AI and Data Science company that has been pioneering machine learning since 2016.

Today, we are building a voice-first platform where millions of conversations will run through, and more than 600 of our virtual agents are live across EMEA and North America. Enterprises like Tryg, DNB, Telenor, and Nordea trust us with their customers.

By joining us, you are stepping into the core of a central, rapidly growing player in the global AI space.

You won't be building theoretical demos or waiting on roadmap slides.

You would be joining early enough to genuinely shape it, and established enough that real customers are already depending on what you ship.

Our team is diverse, dedicated, and a little bit obsessed with getting voice right, and we work hard to make sure everyone here can do the best work of their career.

You will be on the bleeding edge, solving some of the hardest engineering challenges in low-latency computing and genuinely shaping a product that ships directly to massive global enterprises.

The Challenge: Technical First Responder

Real-time voice on enterprise networks is some of the most challenging and satisfying debugging work in software.

When it comes to voice, there is zero forgiveness for latency or dropped packets.

As a Voice Support Engineer, you are right at the intersection of production debugging, networking, and real-time voice.

When something misbehaves on a live deployment, whether it’s call quality, SIP signaling, or integration failures, you are the person who figures out why.

You will be 3rd line support, so it won't just be closing tickets, you will own the puzzle end-to-end. Build small tools and automations in Python to ensure we never have to debug the same issue twice.

Where you can work:

This role is hybrid and based in one of our European offices: Copenhagen, Oslo, Stavanger, Stockholm, Helsinki, or London.

Note: Eligibility to live and work in the Nordics or the UK is required. We are not able to support relocation from outside this region or fully remote arrangements for this position

What you will be doing

You will be the technical owner for voice-related customer incidents, partnering closely with our Voice and Core Platform engineering teams.

This is a role with a clear path to deep technical expertise, you will get direct visibility into the engineering teams building the platform you support.

• Be the Root Cause Detective: Investigate complex production issues across SIP signaling, media flow, networking, and the boost.ai platform. You document and engineer solutions so it doesn't happen again.

• Get Customers Live: Support enterprises through voice integration onboarding, testing, and go-live, including connectivity verification, configuration reviews, and load testing.

• Bring Strong Networking Instincts: Apply your fundamentals (TCP/IP, UDP, NAT, firewalls, routing) to diagnose connectivity issues across messy, highly complex enterprise IT environments.

• Engineer Better Support: Build small tools, scripts, and automations (Python) that improve diagnostics, monitoring, and runbooks. You will turn customer pain into clear signals for platform improvements.

• Communicate Clearly: Translate gnarly, highly technical network issues to non-technical customers without losing them.

What to expect from the day-to-day setup:

• No On-Call: When you are off the clock, you are actually off. There is no on-call requirement for this role.

• Local Business Hours: We work across multiple time zones, but your work happens during your local hours. We offer a high degree of flexibility so you can manage your schedule as agreed upon with your manager.

• Focused Work: Customer-facing meetings are infrequent, allowing you to focus deeply on your core tasks.

• Team Connection: While the day-to-day is highly flexible, you can expect occasional travel for large company-wide or departmental gatherings to celebrate wins and align on strategy.

What we expect from you

You may come from technical support, platform engineering, network engineering, VoIP/telephony, SRE, or customer-facing production engineering.

Note: You do not need to be a SIP expert today. You just need to be the kind of engineer who wants to become one. Deep knowledge of SIP, WebRTC, and telephony can be built here.

Requirements (The Non-Negotiables):

• Hands-on understanding of TCP/IP, UDP, NAT, firewalls, and routing in cloud and enterprise environments.

• Proven experience supporting complex production systems with a real customer-facing component.

• Comfortable writing Python to automate diagnostics, build small tools, and contribute scripts to the platform.

• Excellent ability to manage customer escalations calmly and professionally.

• A degree in Computer Science, Engineering, or equivalent practical experience.

• Fluent in English

Blow us away (Nice-to-haves):

• SIP & Voice Protocols: Hands-on SIP or WebRTC experience is a massive advantage.
• CCaaS & Telephony: Experience with CCaaS platforms, contact-center integrations, or telephony providers.
• An Automation Mindset: We are investing heavily in agentic engineering and automation across support. Familiarity is a bonus; curiosity is essential.
• Observability: Comfort with logs, metrics, and tracing. You know your way around a production incident and can navigate observability tooling under pressure.

The Team & Perks

We work hard on tough challenges, but fun is one of our actual core values. We are an opinionated, high-trust team that celebrates wins together (our annual Boost Camp every October is a massive highlight!).

You will have the room to be independent, opinionated, and innovative. To back you up, we offer a comprehensive range of employee benefits designed to support your overall well-being and allow you to do the absolute best work of your career.
