3What this role really is

A senior technical support specialist handles the difficult technical issues that first-line support cannot resolve. You investigate faults, find root causes, and act as the link between a customer and the engineering team.

4What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

Zendesk Suite (or similar help desk platform like Intercom, ServiceNow) Advanced

Managing complex ticket workflows, building advanced macros and triggers, using reporting features to identify trends, and contributing to the internal knowledge base with high-quality articles.

Salesforce Service Cloud (or similar CRM like HubSpot, Microsoft Dynamics) Intermediate

Viewing detailed customer history, logging intricate activities, understanding case objects and account hierarchies, and pulling custom reports to get comprehensive customer context.

FullStory / LogRocket / Pendo (Product & Session Analytics) Advanced

Watching session replays to reproduce tricky bugs, identifying specific user friction points, and linking session data directly to support tickets for deeper, evidence-based analysis.

Postman / Chrome DevTools (API Testing & Dev Tools) Advanced

Using pre-built and custom Postman collections to test API endpoints, inspecting network requests and console errors in Chrome DevTools to diagnose front-end and back-end errors, and debugging authentication issues.

Tableau / Looker (Data Visualisation) Intermediate

Connecting to various data sources (e.g., PostgreSQL), building new dashboards to track specific customer issues or product areas, and using SQL for complex queries to extract deeper insights.

Confluence / Notion (Collaboration & Docs) Advanced

Designing information architecture for the knowledge base, creating detailed technical documentation and runbooks, and managing project plans for support initiatives within these platforms.

5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Technical troubleshooting approach for a complex customer issue Follows documented procedures; escalates if no clear path is available or if the issue is outside their defined scope. Independently chooses diagnostic tools and methods; consults with peers or Lead on highly ambiguous cases, but owns the initial investigation. Defines best practices for troubleshooting; mentors others on complex diagnostics and helps establish new troubleshooting workflows.
Prioritisation of personal ticket queue Prioritises based on First Response Time SLAs and direct guidance from their Lead, focusing on immediate tasks. Balances SLAs, customer impact, and complexity; proactively communicates any potential delays or reprioritisations to customers and internal teams. Manages queue to proactively identify trends and prevent escalations; influences team prioritisation based on deeper insights into recurring issues.
Creation/Update of Knowledge Base Content Documents solutions following established templates; content is reviewed and approved by a Lead or Senior Specialist before publishing. Independently drafts and publishes new articles based on recurring issues; peer review is encouraged but not always mandatory. Designs knowledge base structure and content guidelines; reviews and approves peer contributions, ensuring quality and consistency.
Escalation to Engineering Escalates issues after exhausting documented solutions, with Lead's approval, ensuring all basic information is provided. Independently decides when to escalate after thorough investigation, ensuring 'steps to repro' are clear, logs are attached, and business impact is articulated. Defines and refines escalation criteria and protocols; coaches team on effective engineering handoffs and managing expectations.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

CSAT/CES on Resolved Tickets
Customer Satisfaction Score / Customer Effort Score
Target · >90% for CSAT; <2.5 for CES (on a 1-5 scale)

A customer gives you a 5/5 for resolving their tricky API integration issue, noting how clear your explanation was. Or, they rate their effort as 'Very Easy' after you guided them through a complex setup.

First Contact Resolution (FCR) for Escalated Tickets
Percentage of complex tickets you resolve without needing further internal escalation to Engineering.
Target · >70%

You take an L1 escalated ticket about a specific database query error and resolve it yourself by digging into logs and using your advanced troubleshooting skills, without needing to send it to Engineering.

Knowledge Base Contribution
Number of new or significantly updated knowledge base articles you publish.
Target · 2-3 articles per month

After solving a recurring issue with a specific data import, you write a clear, step-by-step guide for other agents and customers, making sure it's easy to follow.

Ticket Backlog Age (Your Queue)
The average age of tickets in your personal queue, ensuring issues are actively managed.
Target · No more than 5% of tickets aged over 7 days

You manage your queue effectively so that even complex issues are being actively worked on, not sitting idle for weeks, and you proactively communicate any potential delays to customers.

Technical Root Cause Analysis Quality
Your ability to go beyond the symptom and identify the actual underlying technical problem, providing clear, actionable insights.
  • Engineering teams consistently praise your bug reports for their clarity and completeness
  • fewer 'Can't Reproduce' responses from dev. You're often asked to review others' bug reports before escalation.
Cross-functional Collaboration Effectiveness
How well you work with Product and Engineering to get issues prioritised and resolved, building strong internal relationships.
  • Product Managers proactively ask for your input on new features or bug fixes
  • Engineering Leads trust your judgment on bug severity and often consult you on customer impact. You're seen as a reliable bridge between teams.
Customer Communication Clarity
Your ability to explain complex technical issues and solutions in a way that both technical and non-technical customers understand, managing expectations effectively.
  • Positive customer feedback specifically mentioning clear explanations and helpful guidance
  • fewer follow-up questions from customers after resolution. You can de-escalate situations with clear, empathetic communication.
Mentorship & Peer Support
Providing informal guidance and support to less experienced team members, helping them grow their technical and troubleshooting skills.
  • Junior agents frequently come to you for advice on complex cases
  • positive feedback from peers during team reviews or 1:1s. You actively share your knowledge and best practices within the team.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Solving Complex Puzzles

You'll spend your days digging into tricky technical issues, often involving multiple systems or obscure error messages, where the answer isn't immediately obvious.

Getting a bug report that's vague, then using Postman and Chrome DevTools to pinpoint the exact API call failing and why, finally cracking the case.

Making a Tangible Impact

You'll see your efforts directly translate into happier customers and a more stable product, knowing you've fixed something important that genuinely improves their experience.

Resolving a critical issue for a key customer, then seeing their positive feedback and knowing your work contributed to them renewing their contract and staying with us.

Continuous Learning & Growth

Our product and tech stack are always evolving, so you'll constantly be learning new things and deepening your technical expertise, never getting bored.

Spending dedicated time each week to learn about a new feature or an update to our internal systems, then applying that knowledge to solve a new type of customer problem that stumped others.

What frustrates people
  • The 'Can't Reproduce' Loop: You'll spend ages getting 'steps to repro' from a customer, only for Engineering to say 'CNR' (Can't Reproduce) and send it back to you. It's like a frustrating game of ping-pong sometimes.
  • Fighting for Resources: You'll often find yourself advocating for bug fixes that are impacting real customers, but Product and Engineering might prioritise new feature development over stability. It can feel like an uphill battle to get things prioritised.
  • Vague Customer Reports: Expect tickets that just say 'It's broken' or 'I can't log in' with no context, screenshots, or error messages. You'll need to be a detective just to get the basic information needed to start troubleshooting.
  • Being the Bearer of Bad News: Sometimes you'll have to tell a high-value customer that their issue is an 'edge case' and won't be fixed for months, or that a promised feature simply doesn't exist. It's not fun, but it's part of the job.
  • The On-Call Pager: Knowing that a Sev-1 incident can ruin your weekend or vacation at a moment's notice. It doesn't happen often, but the possibility is always there.
What this role does not give you
  • A completely predictable day – expect urgent escalations to mess up your meticulously planned schedule.
  • Full control over the product roadmap – you'll influence, not dictate, what gets built or fixed.
  • A quiet, heads-down coding role – this is very customer-facing and collaborative, requiring constant interaction.

8Who you work with

Your work directly impacts customer satisfaction, retention, and the overall perception of our product's reliability. You're a critical feedback loop, helping us spot systemic issues and improve the product, which ultimately protects our revenue and brand reputation.

Inside the business
  • Product Management (especially for bug prioritisation)
  • Engineering Teams (for root cause analysis and fixes)
  • Sales (for context on customer accounts)
  • Other Customer Service teams (for escalations and knowledge sharing)
Outside the business
  • Our customers – from individual users to technical contacts at our enterprise clients

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • At least 2 years of hands-on experience in a technical support or customer-facing engineering role, specifically dealing with complex software products.
  • Proven ability to troubleshoot technical issues methodically and document solutions clearly and comprehensively.
  • Experience working with ticketing systems (like Zendesk) and CRM platforms (like Salesforce), demonstrating a solid understanding of support workflows.
  • A track record of effectively communicating complex technical information to both technical and non-technical audiences, both verbally and in writing.

10What to practise next

Where the job is going, and what to do about it starting this week.

Advanced Data Querying & Analysis (SQL & Basic Python)

As our product generates more data, the ability to pull specific customer data, analyse usage patterns, or identify anomalies directly from our databases will become essential for deeper troubleshooting, proactive support, and even spotting trends before they become major issues.

Complex SQL Joins · Basic Python Scripting (Pandas) · Data Visualisation Best Practices · API Data Extraction

  • This week: Take an online course on intermediate SQL (e.g., Codecademy, DataCamp, Udemy) to solidify your querying skills.
  • This month: Practice writing SQL queries to answer common customer support questions (e.g., 'how many times has this user logged in?', 'what features are they using?').
  • Month 2: Start learning basic Python with the Pandas library for data manipulation. Focus on how it can automate tasks you currently do manually.
  • Month 3: Build a simple script to automate a recurring data pull or analysis you currently do manually, demonstrating real-world application.

Quick win: Identify one recurring customer data request that you currently handle manually and figure out how to answer it with a single, efficient SQL query. Save it for future use.

11Staying current once you are in

What people here do to keep up
  • Regularly attending webinars or online courses on new product features or underlying technologies to stay current and expand your knowledge.
  • Participating in relevant online technical communities or forums to learn from peers and share your own expertise.
  • Taking on internal projects that stretch your technical skills (e.g., building a new dashboard, optimising a support workflow, researching a new tool).
  • Mentoring junior team members and actively sharing your knowledge and best practices, helping others grow.

Working with AI on the job

Working with AI

Where AI is starting to help

Imagine spending less time on repetitive tasks and more time on the truly challenging, rewarding technical detective work. Our team is already using AI to make daily life easier, helping you focus on what really matters: solving customer problems and making a real impact.

We're not talking about replacing you; we're talking about giving you a superpower. AI tools are integrated into our support ecosystem to help you work smarter, faster, and with more impact. Here's a glimpse of how you'll be using them day-to-day to level up your game.

Automated Ticket Triage & Routing

An AI model will read incoming tickets, figure out what the customer actually needs, how urgent it is, and then automatically categorise, prioritise, and route it straight to the right agent or team. No more wasting time manually sorting through the inbox – you get straight to the good stuff.

Instant Case Summary Generation

Before you jump on an escalation call or dive into a complex ticket, an AI tool can quickly scan the entire ticket history, linked bug reports, and internal chat, giving you a concise, one-paragraph summary of everything you need to know. Get up to speed in seconds, ready to impress.

First-Draft Knowledge Base Articles

After you've cracked a tough case, an AI tool can analyse your resolution notes and the customer conversation, then automatically generate a draft knowledge base article. You just need to review, tweak, and hit publish, drastically cutting down on documentation time and helping others learn faster.

Smart Reply & Suggestion Engine

As you're typing a response to a customer, our AI will suggest relevant knowledge base articles, macros, or even full sentences based on the context of the conversation. It's like having a super-smart assistant helping you craft the perfect reply, faster and with more accuracy.
